Abstract: An empirical

Abstract: To develop a rigorous, mechanistic design method for asphalt overlays, one must have a method to accurately determine the response of the overlay system to various load conditions. This paper presents a cutting-edge nonlinear ...

Abstract: Capability to effectively discretize a problem domain makes the finite-element method an attractive simulation technique for modeling complicated boundary value problems such as asphalt concrete pavements with material ...

Abstract: With increasing traffic loads and changes in crude petroleum refining techniques, cracking in asphalt pavements continues to be a major cause of structural and functional deterioration of these systems, particularly in ...

Abstract: Low-temperature cracking of an asphalt pavement is caused by the deformation mismatch between the asphalt overlay layer and the underlying pavement layer in cold climates or where rapid temperature change exists. When ...

Abstract: Reclaimed asphalt pavement (RAP) and warm mix asphalt (WMA) have become the primary methods for enhancing sustainability in the asphalt industry in recent years. To further enhance sustainability benefits, asphalt producers ...

Abstract: Flexible overlay systems often fail before reaching their design life due to the occurrence of reflective cracking caused by stress concentrations in the vicinity of joints and cracks in the underlying pavement. In this ...

Abstract: Asphalt paving layers, particularly the surface course, exhibit vertically graded material properties. This grading is caused primarily by temperature gradients and aging related stiffness gradients. Most conventional ...

Abstract: This is a practical paper which consists of investigating fracture behavior in asphalt concrete using an intrinsic cohesive zone model (CZM). The separation and traction response along the cohesive zone ahead of a crack ...
