ASPHALT CONCRETE CHARACTERIZATION FOR PAVEMENT PERFORMANCE PREDICTION (WITH DISCUSSION)

Abstract

Test results conducted at the University of Berkeley and Texas AM (b) In general, the material deformation under load is composed of four components: elastic, plastic, viscoelastic and viscoplastic; (c) The predominant components of the deformation depend on the temperature and loading rate. For example, at high temperatures and fast loading rates, the plastic component constitutes the major part of the residual deformation and the viscoplastic component may be neglected; (d) the viscoelastic component of the deformation, with hereditary memory, is present at all temperatures and loading rates.
