RISTwo-Stage Viscoelastic-Viscoplastic Damage Constitutive Model of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: A two-stage viscoelastic-viscoplastic damage constitutive model is developed for describing different mechanical deformation response of asphalt mixtures under various loading conditions. The model decomposes total strain ...
Approaches to Rut Depth Prediction in Semirigid Asphalt Pavements
Publisher: American Society of Civil Engineers
Abstract: Rutting has an adverse effect on safety and riding comfort of pavement. Reliable prevention and prediction of rutting has been one of the major focuses in road research. This paper summarizes the methods available for rut ...
Developing Master Curves and Predicting Dynamic Modulus of Polymer-Modified Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Four kinds of polymer modifier widely used in China are selected to modify the performance of asphalt mixture: styrene butadiene styrene (China), PR PLAST.S (France), Domix (Germany), and Rad Spunrie (China). The main ...
Investigation on the Diffusion Behavior of Dry Modified SBS at the Asphalt-Aggregate Interface: Molecular Simulation and Experiments
Publisher: ASCE
Abstract: Dry modified Styrene-Butadiene-Styrene block copolymer (SBS) is an innovative method of modifying asphalt mixture that has gained attention due to its convenience, low carbon footprint, and high efficiency. To understand ...
