Most of the pavements are handling the traffic load more than for what they have been designed initially. In addition to the seasonal variation, the pavement is subjected to different temperature throughout the year. For road construction, type of material selected is based on the climatic condition of the location. The quality of binder is refined in order to enhance its performance during service life. In present scenario, use of polymer modified binder is very common to improve binder. In this study, two types of binders are used VG-30 and PMB-40. The changes in physical properties are measured by performing tests like softening point, ductility and elastic recovery on aged and un-aged sample. The testing was performed as per the codal provisions of code IS 1201-1220-1978, ASTM-D 17540 and IRC: SP: 53-2010. The effect of ageing on physical properties of binder is outlined in tabular form.
