Abstract: The Strategic Highway Research Program (SHRP) fatigue crack initiation life prediction model was based on a sophisticated analysis of the results of intensive bending beam fatigue tests under controlled stress and controlled ...

Abstract: It is widely known that pavement fatigue life is often greater than that predicted based on laboratory bending beam or indirect tensile fatigue tests. Among many factors contributing to this difference, the effect of sample ...

Abstract: A two-step approach is proposed to predict the modulus of asphalt concrete from existing micromechanical models. The asphalt concrete microstructure is represented by a two-phase model, which consists of a large spherical ...

Abstract: Friction on a surface covered by an air cavity is much less than friction in water but there is a resistance penalty caused by the cavity tail oscillations. Nevertheless, there is a method ...

Abstract: This paper presents the findings of a preliminary study of the dependence of resilient modulus of cement-stabilized phosphogypsum on various material parameters. In particular, the dependence of the resilient modulus on ...

Abstract: The classical Westergaard idealization of the rigid pavement system assumes that the slab-on-grade can be modeled as a thin elastic plate on a bed of springs. Implicit in this assumption is the Kirchhoff (or thin) plate ...

Abstract: The distresses of asphalt pavement, which include fatigue, rutting, and low temperature cracking, are related to the elastic modulus of asphalt concrete (AC). In addition, the elastic modulus of AC is a design variable for ...

Abstract: As a part of a cooperative effort to provide assistance in the assessment of potential highway construction application areas for industrial residual materials, a knowledge-based system designed to assist in the screening ...
