About this episode
A comprehensive technical overview of asphalt concrete modeling, testing, and performance prediction, primarily focusing on pavement distresses like rutting, cracking, and moisture damage. The text explores complex constitutive models such as the Viscoelastic-Elastoplastic Continuum Damage (VEPCD) and the Disturbed State Constitutive (DSC) models, which are crucial for describing the material's behavior under various loading and temperature conditions. Detailed discussions on material characterization include rheology of modified asphalt binders, stiffness measurement techniques like the complex modulus test, and the use of micromechanics and surface energy to understand adhesion, cohesion, and fracture healing. Furthermore, the material covers practical applications like the Simple Shear Test at Constant Height (RSST-CH) for rutting evaluation and the TCMODEL for predicting thermal cracking, highlighting the transition from empirical to mechanistic-empirical pavement design methods. The sources are presented as excerpts from an engineering book, including contributor lists, terms of use from the copyright holder, and a table of contents.
