Abstract

Asphalt mixes are composite materials with complex microstructure that consists of asphalt binder, air voids, and solid particles with wide size distribution. Micromechanics analysis of asphaltic materials provides useful information on the influence of the material characteristics on the stress and strain distribution within the microstructure. Understanding this distribution is essential to interpret the measured mechanical properties and develop valid stress-strain continuum models. This paper implements a finite element (FE) formulation of gradient elasticity to model the microstructure of asphalt mixes. This model is shown to have the advantages of significantly reducing the influence of FE model resolution, and capturing the effect of particle and asphalt film size distribution on the microscopic and macroscopic response.
