Abstract

The paper aims to model the nonlinear behavior of asphalt concrete numerically. The major constituents of
asphalt concrete are aggregates, air voids and asphalt binders which shows variation in properties depending on various
factors. Therefore understanding the behavior and performance of asphalt concrete is quite complex. The behavior of asphalt
concrete has been treated as pure elastic traditionally. This assumption subjected to high speed traffic loading and low
temperature. Therefore, the behavior will not remained same when asphalt concrete exposed to low speed traffic loading
during high temperature. The research focuses on simulating the viscoelastic behavior of asphalt concrete by incorporating
the laboratory determined properties into finite element model. The mechanical model and three dimensional finite element
models developed numerically in this study help to simulate the behavior and response of asphalt concrete under any traffic
loading conditions.
