Breakthrough concepts in material science is one of the focus areas of the Federal Highway Administration’s (FHWA) Exploratory Advanced Research (EAR) Program and is a critical area of investment to create longer-lasting, more resilient, roadways and structures and preserve existing highway system assets under increasing demands.
While industry has an interest in better performing and more cost-effective materials and academics have and will continue to study material properties, there is a clear government role for encouraging an environment where experimental results and models can be compared and investigators can build on each other’s results. Developing an understanding of the complex materials used in highway infrastructure requires an enormous amount of research. Developing models is hard and software to test and apply the models harder. Integrating analytic approaches from multiple researchers is a whole new ballgame. Yet, that is exactly why and where government leadership is needed to connect the science to applications that will save money and time and provide materials with whole new properties for a next generation highway system.
The EAR Program is taking advantage of new scientific approaches for measuring and modeling materials across multiple length and time scales. It is becoming possible to characterize the chemical and mechanical properties in new ways necessary for controlling and designing complex materials used in roadways and structures. Accordingly, the EAR Program is funding research on multiscale material modeling across multiple institutions and coordinating the results with others conducting similar research. Based on this workshop and similar activities, FHWA is working through the EAR Program with other government agencies and is considering continued investment in moving scientific advances in materials characterization and modeling into the design and use of radically new materials.

16. Abstract This report summarizes a 2-day workshop held to share information on multiscale material modeling. The aim was to gain expert feedback on the state of the art and identify Exploratory Advanced Research (EAR) Program opportunities for multiscale material modeling as it applies to the optimization of properties, durability, and construction of asphalt and cementitious pavement and construction materials. The workshop provided an opportunity for researchers who develop material models and engineers who we the results of material models to discuss multiscale modeling of cementitious and asphaltic materials. Discussion topics included the purposes and audiences for current and future models, the state of the art in approaches to model degradation mechanisms across length scales, and technical and programmatic approaches to advance multiscale modeling methods. These discussions will form the basis for transition of results from research on multiscale material modeling and new plans for EAR Program activities. |
