      <title>Engineering Assessment of Drive Point Data for Improving the Prediction of Geomaterial Properties and Design &amp; Construction of Pile Foundations</title>
      <link>https://rip.trb.org/View/2732353</link>
      <description><![CDATA[Highway projects require site investigation (SI) to determine subsurface information for engineering designs and constructions. The subsurface information may include geological profile, geomaterial properties, groundwater, bedrock, and any potential subsurface problems. Some common purposes of the SI include (1) the identification of construction materials, (2) design and construction of highway infrastructure, (3) geomaterial sampling and characterization, (4) planning for the construction technique, and (5) determination of potential subsurface concerns. Due to geological uncertainty and inherent variability of natural soil and rock materials, site characterization typically represents a large share of the geological/geotechnical engineering budget (Coduto et al., 2011). SI typically consists of four main parts: (1) antecedent investigation, (2) field investigation, (3) laboratory testing, and (4) technical reporting. Antecedent investigation provides the basis for subsequent field investigation, and field investigation allows in-situ testing and geomaterial/groundwater sampling for laboratory testing. The SI can lead to the largest source of uncertainties in the design and construction of pile foundations (Oluwatuyi et al., 2023). The most cost-effective SI approach suggested by Handy (1980) is the one with a variability consistent with the variability of the subsurface profile. That is, a few precise tests for a uniform deposit and more tests for an erratic deposit. The current field investigation practice of the Wyoming Department of Transportation (WYDOT) Geology Program involves driving a 1¾-inch hollow steel rod with a 2-inch conical tip known as the drive point (DP). Although ASTM standard is not available, the current DP has been implemented by the Geology Program as part of the SI since the 1960s, and different hammer types with varying efficiencies have been used for driving the DP over decades. In the past 10 years, the DP driving has been conducted using a 140-lb automatic hammer mounted on a drill rig and a hammer stroke height of 30 inches. The automatic hammers of the WYDOT Geology Program are calibrated periodically, and the hammers have efficiencies of more than 90% (Hannigan and Klesney 2017). DP blow count is recorded every one-foot penetration of DP. The DP blow counts provide a “continuous” profile of the relative denseness of the subsurface, and driving refusal can vary between 30 to 400 blows per foot. The WYDOT Geology Program has been using DP in every SI except for gravel pits and rock quarries. The DP blow count helps geologists and geotechnical engineers to: (1) better understand the subsurface profile through the relative denseness, (2) make a better decision during the field investigation regarding locations or depths of in-situ testing and sampling, (3) identify in-situ test methods, and (4) select drilling methods required to successfully complete a test hole. On the other hand, the DP measurements are not intended for determining rock rippability, soil types, rock lithology, nor bearing capacity of geomaterials. For a project site, DP is often conducted first to understand the subsurface profile and condition before drilling more boreholes, conducting Standard Penetration Test (SPT), and collecting undisturbed soil samples using a thin-wall Shelby Tube. Although borehole drilling can provide a continuous log of the lithology, it can be hard on determining pile refusal depths, settlement zones, and other subsurface problems. SPT is often conducted at every 5 ft and can only provide a discrete snapshot of subsurface conditions. In addition, Shelby-tube sampling is often conducted at the mid-depth of a soil layer for a length of 1 to 2 ft. Although the Cone Penetration Test (CPT) provides a continuous measurement of soil properties, a smaller conical tip of CPT is not suitable for a typical subsurface with boulders, cobbles, and hard gravelly layers in Wyoming. The overall goal of the proposed research is to improve the performance of transportation infrastructures in Wyoming. Recognizing the advantages and some challenges with the DP method, this research project is proposed to accomplish three main objectives: (1)	improve the understanding of subsurface profiles and conditions; (2) scientifically and statistically develop relationships between DP and geomaterial properties; and (3) improve the design and construction of driven piles using the DP method.

The proposed research will have the following outcome measures: (1)	SI performances: The proposed DP method will improve the overall performance and effectiveness of the SI. The proposed DP method will improve the understanding of subsurface conditions and allow for better decisions on subsequent geotechnical testing and geomaterial sampling.
(2)	Engineering performances: Equations will be developed to predict geomaterial properties, strength measures, and pile resistances based on DP data. These outcomes will improve the performance of geotechnical engineering design and construction.

      <title>Development of an Innovative, Bio-Mediated, Self-Healing Concrete Technology</title>
      <link>https://rip.trb.org/View/2717327</link>
      <description><![CDATA[Cracks in concrete structures significantly compromise their durability, and it is difficult and expensive to timely inspect transportation assets and treat concrete cracks. Self-healing concrete has a unique advantage in this regard. Concrete exhibits a self-healing capability as a result of hydrating unhydrated cement. However, such healing performance is limited to cracks less than 0.1mm wide. Several approaches to self-healing concrete have been tried in the past, but so far none has been shown to be adequate. For example, self-healing based on encapsulated chemicals offers only one-time healing. Microbial induced mineral precipitation heals only concrete cracks no more than 0.4 mm wide. 

For NCHRP 20-30/IDEA 261, the research team will develop a fungi-mediated, self-healing concrete technology for fast and efficient healing of cracks greater than 1mm wide autogenously. Another feature of this technology is that the treated concrete shows strong hydrophobicity that inhibits the ingress of water and deicing salt solution into the concrete. The autogenous self-healing concrete technology is based on bio-mineralization through fungi. Fungi strains that can survive and grow in concrete’s high alkaline environment will be identified, and microcapsules filled with these fungi will be introduced into the concrete. Cracks appearing in the concrete will be quickly covered by fungi fibers through the process of biomineralization. The fungi fibers, being hydrophobic, will also inhibit the ingress of water into the concrete and protect it from damage caused by freezing and thawing of pore water and corrosion of reinforcement steel by deicing salt solution entering through the cracks. 

Field evaluations will follow laboratory-scale evaluation and optimization. Field work will require scaling up the fungi microcapsules production process. One option will be to use multiple peristaltic pumps in parallel to enhance the rate of microcapsule production. Concrete mixture designs will be developed and optimized with respect to the quantity of fungi microcapsules. Ohio Department of Transportation will collaborate in field tests and has committed to providing active construction projects as possible field sites for testing the technology.]]></description>

      <title>Evaluation of a Local Carbonate Aggregate Source for Pavement Surface Applications in the Bristol District</title>
      <link>https://rip.trb.org/View/2714406</link>
      <description><![CDATA[The purpose of this project is to evaluate the field frictional performance of surface paving applications incorporating a local carbonate aggregate source to support potential approval for use in surface applications in the Bristol District. This purpose will be accomplished through coordinated field trials, laboratory characterization, and continued monitoring of existing field sites. Specifically, the study will: (1) further evaluate the performance of existing field projects in the Bristol District to determine whether conclusions drawn from short-term performance monitoring remain consistent over a longer evaluation period, and (2) implement and monitor additional field trials incorporating carbonate aggregates in pavement preservation treatments and surface asphalt mixtures on roadways carrying traffic volumes greater than 750 ADT.
The scope of this study includes friction and surface texture measurements of 14 field sections consisting of carbonate aggregate treatment sections and, where applicable, companion reference sections incorporating conventional non-carbonate aggregates. The evaluated sections will include both pavement preservation treatments and surface asphalt mixture applications. These field sections will be systematically monitored throughout the study period to assess friction and texture performance trends over time and to further evaluate the long-term field behavior of the local carbonate aggregate source under varying traffic conditions.

      <title>In-Situ Monitoring of Concrete Early Age Strength Development Through Acoustic Resonance Technologies</title>
      <link>https://rip.trb.org/View/2689759</link>
      <description><![CDATA[In this project, a novel acoustic resonance technology for in-situ monitoring of the early age strength development of concrete and cementitious mixes will be investigated. This technology leverages the fundamental principle that the mechanical properties of a material, including stiffness and strength, are intrinsically linked to its acoustic response. By continuously measuring changes in acoustic resonance frequencies as concrete cures and gains strength, this approach offers a direct, real-time, and non-destructive method to assess in-situ strength development without the need for destructive coring or reliance on proxy specimens. Unlike traditional strength evaluation methods, which require extensive laboratory processing, this technique enables on-site deployment, allowing engineers and contractors to make immediate, data-driven decisions regarding construction sequencing, formwork removal, and traffic opening times. The project will focus on optimizing the acoustic resonance technique for field applications by integrating laboratory investigations, field tests, and data analytics. Experimental studies will be conducted to establish correlations between resonance frequency shifts and conventional strength metrics for various cementitious mixes, including rapid-setting and high-performance concrete used in critical infrastructure projects. By offering a practical and real-time alternative to conventional methods, this technology has the potential to improve project scheduling, reduce costs, and ensure safer, more durable concrete structures with minimal disruption to transportation networks. Ultimately, the success of this project will provide a transformative solution that enhances the speed, reliability, and efficiency of strength monitoring and promotes the implementation of in-situ concrete strength monitoring technology by validating the accuracy of the testing data, understanding the influence of external conditions on the performance, and developing implementation details with practical recommendations for future applications in transportation infrastructure projects.]]></description>

      <title>Field Friction Testing</title>
      <link>https://rip.trb.org/View/2672003</link>
      <description><![CDATA[The primary goal of this project is to perform comprehensive field friction testing on various Stone Matrix Asphalt (SMA) surfaces with polymer-modified asphalt binders (i.e, “H” and “V” binders) across the entire state. Conducting these tests in real-world conditions is crucial for identifying potential safety concerns related to skid resistance. Previous year friction testing conducted on certain SMA surfaces within the SE region using the “V” binder indicated that these surfaces exhibited notably lower skid resistance values compared to other SMA surfaces after few years of construction. Building on these findings, this project intends to carry out an additional round of field friction measurements targeting those same SMA surfaces in the SE region, while also expanding the scope of testing to include more SMA sections throughout the state. The data collected from this expanded field testing will be instrumental in determining whether the relatively low friction numbers are attributable to the specific type of binder used, the aggregate materials involved, or a combination of both factors. Furthermore, to gain a broader understanding of the current skid resistance condition of the state’s pavement infrastructure, several additional pavement sites will be evaluated as part of this study. This holistic approach aims to provide actionable insights that can guide improvements in pavement design and material selection to enhance overall road safety and durability.]]></description>

      <title>Develop and Demonstrate an Evaluation Process for Acceptance of Additives for Use in Forensic Analysis in Hot Mix Asphalt</title>
      <link>https://rip.trb.org/View/2666836</link>
      <description><![CDATA[Although additives, modifiers, and extenders are commonly used in hot mix asphalt (HMA) designs, a robust and structured laboratory evaluation process is needed to assess their impact on performance and minimize the risk of incorporating these materials in routine use. The research team will develop a framework to evaluate new products in the context of asphalt materials, leveraging insights from existing methodologies such as NCHRP 1-130. The study will assess asphalt binders and mixtures, considering material selection, laboratory performance, and field validation using test sections. The final deliverables will include a laboratory assessment framework, performance-based criteria, and a template for long-term monitoring of additives in HMA.]]></description>

      <description><![CDATA[This project is primarily about controlling water in pavement foundation layers for increased pavement performance. This study proposes to remove water out of the pavement systems via use of geotextile fabric (moisture management geotextile) as a separation layer in pavement foundation systems to mitigate the damage that occurs due to high moisture contents. The workplan consists of constructing sites with these innovative geosynthetics and conducting field tests and analyses. The field tests will include lightweight deflectometer, falling weight deflectometer, moisture and temperature monitoring through depth.]]></description>

      <title>Innovations Deserving Exploratory Analysis--The Transit IDEA Program. IDEA 108. TrainMate - Let's Make Public Transportation Public</title>
      <link>https://rip.trb.org/View/2572327</link>
      <description><![CDATA[This is a follow-on project to a recently completed Transit IDEA Project T-100 in which the research team  developed the designs and studied the feasibility of a robotic system, TrainMate, to assist passengers with disabilities at non-accessible street level train transit stations. The project successfully produced electromechanical blueprints as well as software components of the proposed robotic system and ran them through end-to-end software simulations to ensure that they could work in real-life scenarios and be used to take the research to  the prototyping phase  In this Type 2 project, a prototype version of the TrainMate will be built and its capabilities demonstrated in enabling individuals using mobility devices to independently board and deboard trains efficiently and conveniently. 

The project work will involve building a physical full-scale prototype unit with focus on meeting the specific requirements of the users and the transit agencies. In the earlier proof-of-concept project, 3-D models of the system were designed, and the integrated system components were tested in various simulation environments. The results validated the proposed prototype design. Several software systems were  surveyed or developed dealing with artificial intelligence, autonomous navigation, machine vision, robotic operating system, and the speech to text and text to speech capability to establish the feasibility of the integrating software components with the electromechanical components.  In this follow-on project, those software systems will be further developed and tested on the prototype platform to ensure their applicability and useability. The fully working prototype unit (robotic base and the wheelchair lift module) including the sensor network and software components, shall pass all technical verifications and tests conducted in laboratory set-up in a mockup train station. The system will be made ready for pilot program testing. New Jersey Transit will allow access to one of its railyards to test the system in a safe and controlled environment using real railcars before moving on to the public train stations. The TrainMate system will be taken to different train stations identified by the NJ Transit and tested over several months in actual public transportation environments to assess its field readiness, useability, and applicability to serve the intended use. A passengers’ survey will be conducted for their feedback on their satisfaction with the TrainMate system. Calibration and enhancement of the system will continue. Finally, the project will be concluded with a field demonstration before invited officials and NJ Transit executives  at the New Jersey’s Hoboken train station.

The benefits of the robotic TrainMate system are significant, particularly for disabled passengers who require accessible transportation. With TrainMate, this disadvantaged section of the public will no longer have to rely on assistance from others or deal with limited mobility when using public transportation. It will be a safe, reliable, and convenient way for them to travel with confidence, providing them with a greater sense of independence and autonomy. ]]></description>

      <title>Michigan (One Point) Cone Test Evaluation</title>
      <link>https://rip.trb.org/View/2562261</link>
      <description><![CDATA[Recent use of Open Graded Drainage Course (OGDC) has drawn the attention of Michigan Department of Transportation (MDOT) to the current practice of using One-
Point Michigan Cone tests to determine Maximum Density for such soils. The material is relatively new to MDOT, and the research team desires to discover if current field tests involving the Michigan cone correlate with other industry standard tests.
Studies from the 1960's, 70's and early 2000's indicate that for many applications, Michigan Cone Maximum density
values exceed those garnered by other acceptable testing methods. The department would like to explore if Michigan
Cone testing practices as written are an effective determination of Maximum density for OGDC, or if modifications to
this current process are more appropriate for determining this maximum density. MDOT would prefer to keep its current equipment for field testing without investing in ovens for oven dry moisture, generators, new volumetric
molds or hammers, so a preference exists to manipulate our current processes to give a representative sample of the
maximum density.]]></description>

      <title>Camera Based Computer Vision Measurements for Bridge Field Testing</title>
      <link>https://rip.trb.org/View/2512627</link>
      <description><![CDATA[The objective of this proposal is to develop a framework and necessary tools to field test bridges using computer vision including either low-cost ground cameras or off-the-shelf drones. Instead of using conventional displacement/strain sensors and data acquisition system, a few cameras or a fleet of drones each equipped with a camera will be deployed for the measurements. To achieve this goal, the following will be carried out (1) literature review, (2) evaluation of current products that utilize computer vision for measurements, (3) development of low-cost tools for bridge field testing using stationary cameras and/or drones, (4) development of field-testing frameworks, and (5) load testing a few bridges to validate/refine the tools. The project main benefit is to reduce the bridge field testing time, effort, and costs through computer vision without the need for conventional sensors.]]></description>

      <title>Low-Cost Internet of Things Sensors to Support Avalanche Monitoring Programs</title>
      <link>https://rip.trb.org/View/2505726</link>
      <description><![CDATA[This project will develop a novel avalanche monitoring system to automatically provide remote temperature and snowpack movement information to assess roadside avalanche risk and monitor avalanche activities. Drones will deploy the monitoring units into hazardous avalanche release zones and, at the end of the season, retrieve them. Stage 1 work will focus on developing and validating the basic functions and performance of the selected hardware and material, conducting simulation and small-scale real-life experiments, and making any necessary adjustments to the fundamental factors of the designed system. Optimal temperature sensor, GNSS (location) sensor, accelerometer, antennas, motherboard, and batteries will be selected to ensure compatibility and functionality of all components of the system. Each component's operations will be activated and integrated into the motherboard to optimize weight, performance, and reliability. An avalanche monitoring unit shell will be designed. The shell design will accommodate a drone delivery/retrieval mechanism. A weatherproof robust base station will be designed and constructed for positioning near the avalanche slopes of interest. The base station will receive data from multiple avalanche monitoring units, compile this information into a data log, and facilitate remote access of this data via an Internet connection. Simulations will be carried out in laboratory and outdoor settings to test the system under varied conditions and the collected data will be analyzed to guide enhancement of system. In Stage 2, the system will be refined in terms of design, robustness, and effectiveness based Stage 1 work. A full-scale experiment to evaluate the performance of the revised system will be conducted at Snoqualmie Pass above Interstate-90 in the Cascade Mountains. The system may go through several improvement and refinement iterations before it is deemed complete and fully operational. After system improvements, comprehensive real-life testing will be carried out in the Cascade Mountains. The testing may include multiple "test-revise" cycles, allowing for further refinement of the system based on real-world feedback and performance metrics. The final report will provide all relevant data, methods, and conclusions along with guidance on how to use the developed system.]]></description>

      <title>Evaluating Minimum Virgin Binder Contents for Durable Recycled Asphalt Pavement (RAP) Mixes</title>
      <link>https://rip.trb.org/View/2437680</link>
      <description><![CDATA[Economic factors and environmental sustainability are driving the use of more reclaimed asphalt pavement (RAP); however, durability of those mixes has been a concern. Various approaches (e.g. limiting RAP usage, increasing lab-molded density, or balanced mix design (BMD)) have been tried to improve mix durability. All the approaches point to one essential factor for durable RAP mixes: minimum virgin binder content. Thus, the research team will determine the minimum virgin binder content(s) for durable RAP mixes. The researchers will review the literature to identify critical factors affecting RAP mix durability. Considering all those critical factors, the research team will develop and execute a statistically sound laboratory experimental design to develop the relationships between cracking properties measured by Overlay test and Ideal cracking test and mix components (e.g. virgin binder content) and their characteristics. Furthermore, the research team will assess field performance of RAP mixes and delineate the correlation between field performance and laboratory mix cracking properties. Subsequently, the researchers will recommend minimum virgin binder contents based on the relationships among field performance, mix cracking properties, and mix components and their characteristics, and develop guidelines, update specifications, and organize training sessions.]]></description>

Researchers will obtain detailed Continuously Reinforced Concrete Pavement (CRCP) structural responses from field experiments, analyze the data, and develop the optimum steel designs for thick CRCP. The research team will develop and present field experimental plans to the Texas Department of Transportation (TxDOT) for its feedback and concurrence. Once TxDOT approves, the research team will conduct field testing per the approved experimental plans and present the data and its analysis results as well as its implications to the research team. Researchers will also provide any technical assistance that might be needed for the implementation of the findings.]]></description>
