DEM models of idealized asphalt mixtures
The stiffness behavior of an idealized asphalt mixture at the different air void levels was investigated in this paper. The asphalt mixture was modeled with the discrete element modeling (DEM) approach by randomly generated air voids in two dimensions (2D) and three dimensions (3D). Air voids were calculated within the DEM model to meet the specific air void level (i.e. 4%, and 10%). Sixteen di…
Two dimensional and three discrete element models for HMA
Hot Mix Asphalt (HMA) is a composite material that consists of mineral aggregates, asphalt binders and air voids. A Discrete Element Model (DEM) of the HMA microstructure was developed to study the stiffness behavior in both two dimensions (2D) and three dimensions (3D). Image analysis techniques were used to capture the HMA microstructure. The HMA microstructure was divided into two phases: ag…
Structural Health Monitoring of Long-Span Suspension Bridges
Long span suspension bridges cost billions. In recent decades, structural health monitoring systems have been developed to measure the loading environment and responses of these bridges in order to assess serviceability and safety while tracking the symptoms of operational incidents and potential damage. This helps ensure the bridge functions properly during a long service life and guards again…

Towards Improved Characterization of Cemented Pavement Materials
Increasing use of high productivity road freight vehicles combined with more sophisticated approaches to pavement analysis has led to the need for improved knowledge of the performance of pavement materials. This paper describes the development of laboratory tests intended for routine assessment of strength, modulus and fatigue properties of cemented pavement materials. The laboratory tests inv…
