Using frequency sweep strain control to study the rheological properties of Malaysian's asphalt binder

摘要

The aim of this study is to investigate the rheological properties of three grades of virgin bitumen 40/50pen, 60/70pen and 80/100pen using the frequency sweep strain control. Several road pavement distresses are related to rheological properties of bitumen. Rutting and fatigue cracking are the major distresses that lead to permanent failures in pavement construction. There is thus growing demand for the study the rheological properties of bitumen using high accuracy device such as Dynamic Shear Rheometer (DSR). Frequency sweep strain controlled test and penetration test has been conducted to investigate the rheological properties of the three grades of bitumen. The results shows that value of G*, G', G" and the viscosity are higher in harder bitumen and its match with the penetration tests results.
