Summary
This document summarizes the activities and findings of the Federal Highway Administration’s (FHWA) Exploratory Advanced Research (EAR) Program through its Research Associateship Program (RAP) in 2016. The EAR Program facilitates high-risk, long-term research by hosting postdoctoral and senior scientists to investigate emerging issues in highway transportation. The report details specific projects across materials science, human behavior, and performance assessment, highlighting how these short-term collaborations advance FHWA’s strategic goals. In materials science, researchers addressed structural durability and pavement longevity. Danial Esmaili analyzed large-scale tests on geosynthetic-reinforced soil (GRS) bridge foundations, finding that reinforcement spacing significantly influences deformation more than reinforcement strength, and that limiting bearing pressure to 10% of estimated resistance keeps axial strains below 0.5%. Jessica Silva developed inorganic curing compounds using metal-oxide materials to create durable coatings that address the degradation issues of traditional organic membranes. Jose Muñoz investigated nano-additives applied as thin films to aggregates, demonstrating that judicious placement of nano-aluminosilicate gels improves the interfacial transition zone in concrete, enhancing mechanical strength and reducing permeability. Regarding vehicle dynamics and safety, Emmanuel Bolarinwa developed vehicle-tire friction models to predict safety performance metrics, such as stopping distances, using simulation packages verified against naturalistic driving data. His work aims to establish theoretical friction thresholds for pavement maintenance. In human behavior research, Alicia Romo created a framework for integrating data from driving simulators, crash databases, and naturalistic studies to better understand road-user errors. Nopadon Kronprasert used microscopic traffic simulation to evaluate the operational and safety impacts of alternative intersection designs, including restricted-crossing U-turns and miniroundabouts, providing data to support their implementation. Kun-Feng Wu advanced crash data modeling by validating surrogate safety measures using naturalistic driving data, allowing for more precise prediction of crash sequences and faster evaluation of safety countermeasures. Finally, in performance assessment, Jong-Sub Lee investigated mechanistic models for asphalt mix design, finding that increasing voids in mineral aggregate (VMA) while decreasing air void content significantly improves fatigue life and damage characteristics. Collectively, these projects illustrate the EAR Program’s role in leveraging cutting-edge scientific approaches to solve critical infrastructure challenges, from improving material durability and intersection safety to enhancing predictive modeling for pavement performance and crash prevention.
