The Development and Evaluation of a Virtual Testing Procedure for the Prediction of the Cracking Performance of Hot Mix Asphalt

The Development and Evaluation of a Virtual Testing Procedure for the Prediction of the Cracking Performance of Hot Mix Asphalt Zheng, Feng Primary Author mixed material bibliography ASCE 2010 id Indonesia pp. 142-158 Pavements And Materials: Testing And Modeling In Multiple Lengths Scales Motivated by the ultimate goal of linking the binder and aggregate properties to the cracking performance of asphalt concrete, a multiscale virtual testing methodology is developed in this paper. The main components of the proposed methodology are: (a) a virtual fabrication technique that generates the microstructure of asphalt concrete specimens without the need for physical fabrication, (b) a lattice modeling approach that simulates the micromechanical behavior of cracked asphalt concrete specimens, and (c) a multiscale methodology that incorporates the effects of aggregates of widely varying sizes. The resulting methodology is calibrated to simulate the load?deformation behavior of real uniaxial tension test specimens. A comparison of the predicted response against the measured response indicates that the proposed method shows promise, but requires further work aimed at the fundamental understanding of the micromechanical behavior.
