Abstract

Understanding the deformation behaviour of asphalt mixtures in real pavements relies on understanding their behaviour under various loading and environmental conditions. In this paper, the deformation behaviour of two asphaltic mixtures under uniaxial tensile and compressive cyclic loading/unloading conditions is presented. Repeated creep recovery tests undertaken to failure exhibit the same shape curves as a continuous creep test, with primary, secondary and tertiary creep regions. Results from the compressive testing show that the total and permanent strains decrease after an initially high first cycle and then remain fairly constant until increasing as damage occurs. The behaviour of the material in tension is qualitatively similar to that in compression, although the initial decrease in total and permanent strain is less significant and the increase in recovered strain accelerates more towards the end of the test.
