Abstract

© 2015 Elsevier Ltd. All rights reserved. Experimental data for pure bitumens and simplified theoretical models for their deformation behavior are assembled into a single framework that summarizes their steady-state inelastic response to stress. A number of response regimes are identified: a low-temperature elastic regime, a low-temperature plastic regime, a power-law creep regime, and a Newtonian flow regime. Data for a number of pure bitumens are fitted to constitutive equations for each regime. The equations are then used to construct deformation-mechanism maps for a particular type of bitumen commonly employed in pavement construction in the UK. These diagrams relate strength to temperature and strain rate over a wide range of variables.
