Abstract: Adhesion between asphalt binder and aggregate in a dry state as well as in the presence of water is critical to the performance and durability of asphalt mixtures. According to the literature, distress mechanisms in asphalt ...

Abstract: Moisture damage in asphalt concrete pavements is a major cause for high maintenance costs of state and federal highways. Moisture damage in asphalt concrete is largely due to loss of adhesion between bitumen and aggregate, ...

Abstract: It is almost axiomatic that an effective international agreement to limit emissions of

Abstract: Civil engineers are at times required to stabilize sulfate-bearing clay soils with calcium-based stabilizers. Deleterious heaving in these stabilized soils may result over time. This paper addresses critical questions ...

Abstract: In this paper, a method is developed that results in guidelines for selecting the best Ordinary Differential Equation (ODE) solver and its parameters, for a class of nonlinear hybrid system were impacts are present. A ...

Abstract: Expansive clay soils—those that change significantly in volume with changes in water content—are the cause of distortions to structures that cost taxpayers several billion dollars annually in the United States. Much has ...

Abstract: Hydrated lime is evaluated as a filler in bitumen and is compared to similarly sized filler comprised of calcium carbonate, limestone. Extensive laboratory testing is considered, including rheological testing of mastics ...

Abstract: A performance test, rather than an empirical test, to evaluate rutting susceptibility is needed to accompany current volumetric property requirements of airport hot mix asphalt (HMA) designed using a superpave gyratory ...

Abstract: Asphalt mixes exhibit a viscoelastic-viscoplastic behavior, and the contribution of the different constitutive components depends on the temperature and rate of loading. This paper presents an anisotropic nonlinear ...
