Abstract

The field performance of bituminous roads depends highly upon the rheological properties of the bitumen used. Therefore, it is paramount that the determination of the rheological properties of bitumen binders is done accurately. Determining the time it takes for a specimen to reach the desired test temperature before starting any rheological examination is one such important aspect. This time is known as the time for thermal equilibrium. This study focuses on determining the time it takes for a specimen to achieve the thermal equilibrium. Here, the unaged, rolling thin film oven (RTFO) aged and pressure aging vessel (PAV) aged bitumen binders were subjected to an oscillatory test at 10 rad/s using a Dynamic Shear Rheometer (DSR) and the variation of the complex modulus with time was analyzed. The observed results clearly showed that the test temperature and aging significantly affects the time it takes for a sample to reach the thermal equilibrium.
