Abstract
This paper presents the properties of Malaysian paving grade conventional binders 80/100 and 60/70 subjected to multiple stress creep and recovery test (MSCR) at 58, 64 and 70°C. The dynamic shear rheometer was used to carry out this test. Measurements were made on unaged, quarry short-term aged, and Rolling Thin Film Oven Test aged samples at two stress levels, 100 and 3200 Pa. The delayed viscoelastic response was evaluated with recoverable strain and the resistance to permanent deformation with non-recoverable compliance. The results and variations at different stress levels are substantially different among both binders at different stages of ageing. In general, the percentage recoveries are higher for short-term aged compared to unaged binders. The process of ageing was found to decrease its Jnr values at all MSCR test temperatures and stress levels which indicate that short-term aged asphalt binders are less susceptible to rutting than unaged binders.
