      <title>A Pavement Management System for Wyoming County Roads</title>
      <link>https://rip.trb.org/View/2394544</link>
      <description><![CDATA[A pavement management system (PMS) is an asset management tool that helps decision-makers determine the most effective strategies for maintaining pavements in optimal condition within a specific timeframe. Most highway agencies in the United States employ PMS to proficiently and effectively manage their pavement assets on state roads. Unlike the state level, most local agencies administering county roads have yet to implement PMS. This may be attributed to insufficient resources, technical proficiency, and data availability and quality limitations. Hence, this research proposal addresses this gap by developing a comprehensive PMS for Wyoming county roads. The development of this PMS will follow a multi-stage approach based primarily on data collected via questionnaire survey and historical pavement conditions. This proposed project is expected to result in a PMS tailored for Wyoming counties, which will incorporate historical pavement conditions, alternatives and costs of maintenance and rehabilitation (M&R) treatments, decision trees for effective treatment selection, a prioritization framework for M&R treatment scheduling, and financial requirement assessment. The findings and the developed PMS will not only assist Wyoming counties in effectively and efficiently managing their roads, but they will also offer guidelines and recommendations that could benefit counties in other states.]]></description>

      <title>MnDOT Haul/Detour Routes – Impacts on local roads</title>
      <link>https://rip.trb.org/View/1764601</link>
      <description><![CDATA[The traffic load on local roadways have changed significantly due to the traffic added from detour and haul routes. Minnesota state law limits the weight of vehicles by individual axles and gross weight. While these laws standardize traditional vehicles by size and weight, when a new pavement is being built, large volumes of heavy vehicles are sometimes diverted through local roads. However, the local road network is often inadequate as these roads are not designed to handle such volume and weight of vehicles. The costs of the resulting premature pavement failure, maintenance, and rehabilitation are the responsibility of local roads authorities who are not generally able to absorb these additional costs. Currently, Minnesota Department of Transportation (MnDOT) determines compensation in these circumstances based on gas tax income generated by the truck highway traffic detoured onto a local roadway. However, there are apprehensions regarding the adequacy of this compensation method to address the damages to the roads. Therefore there is a need to objectively investigate alternative approaches to quantify the reduction in pavement life due to additional traffic in haul/detour routes, and costs associated with this traffic. The primary goal of this study is to analyze alternative “equivalent compensation” methods and develop an agreed-upon approach with stakeholders. This will be achieved through four major tasks: (1) identify, quantify, and evaluate the impacts of changed traffic on the current local roadway systems, (2) forensic investigation on statewide sites, (3) conduct compensation analyses via use of different equivalent compensation methods, (4) develop a web-based tool on the agreed-upon compensation method. The outcomes of this research are anticipated to substantially extend the service life of the local Minnesota road system.]]></description>
