      <title>Assessing Presence and Impact of REOB (Recycled Engine Oil Bottoms) on Asphalt (1.19)</title>
      <link>https://rip.trb.org/View/1994174</link>
      <description><![CDATA[Asphalt material producers sometimes incorporate Recycled Engine Oil Bottoms (REOB) into paving asphalt in order to alter its performance grade (PG). State Departments of Transportation express concern that REOB decreases pavement lifetime, even though it does not violate the specifications that are intended to ensure good performance. This research project assesses REOB in asphalt through two complementary approaches: (1) experimental measurements to detect presence of REOB in asphalt binders used in Rhode Island, and (2) molecular simulations to quantify mechanisms about how REOB alters asphalt mechanics, meaning viscosity and complex modulus G*. Prior work at URI has indicated that Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) can identify REOB presence while simultaneously suggesting a metalbased fingerprint of asphalt chemistry. Other prior work at URI has developed nanoscale model systems that replicate asphalt properties within molecular dynamics simulations. In this project, the intent of approach (1) is to provide ICP-MS experimental data that complement simultaneous development at RIDOT of a REOB detection approach based on X-ray fluorescence (XRF). The intent of approach (2) is to identify rheological distinctions to anticipate between systems with and without REOB. Such perspectives can then be applied toward interpreting effects of REOB on measured asphalt DSR data and can guide rheology studies in future work.]]></description>

      <title>Determining the Oxidation Stability of Biodiesel Produced from High Stability Oils</title>
      <link>https://rip.trb.org/View/1228259</link>
      <description><![CDATA[High stability oils have recently received significant interest because they are healthier oils and have improved commercial frying performance. The increased adoption of the high stability oils will ultimately result in their use as feedstocks for biodiesel production. Several high stability oils, with varying compositions, are commercially available; however, the effect of the feedstock composition on the biodiesel composition and properties is unknown. This project will investigate the effect of oil composition on biodiesel properties, specifically fuel stability. It is hypothesized that a higher oxidation stability of the parent oil will result in improved fuel stability, but no systematic studies have been reported. The long term goal of this work is to develop a multi-investigator team analyzing fuel production and fuel performance/emissions from stationary and onboard engines. This approach would provide a feedstock to tailpipe study of alternative fuels, consistent with the Transportation Research Institute's (TRI) vision.]]></description>
