Mechanistic Analysis and Design of Mixtures and Pavements Using Two-Way Coupled Multiscale Computational Modeling

This study presents a mechanistic method that can simultaneously design all three primary length scales (i.e., mixture components, mixture, and structure) in highway/airfield pavements. It directly links the properties of bituminous mixture components and mixture design to pavement structural design via a two-way coupled multiscaling. The details to demonstrate how the approach can design all three length scales simultaneously are given. The bituminous mixture variables include the gradation and elastic properties of aggregates, the viscoelastic properties of fine aggregate matrix, and the fracture properties of the fine aggregate matrix, all of which can be obtained from small-scale tests. The modeling concept was applied to the Federal Highway Administration-Accelerated Loading Facility (FHWA-ALF) test section. The preliminary results imply that pavement structural design and mixture design can be conducted concurrently in a purely mechanistic way with only mixture component properties, which will lead to significant cost-time savings compared to other currently available approaches.
