The purpose of this study is to evaluate the effect of sasobit as a modifier on the performance of bitumen
at high temperatures. Mixes with different percentages of sasobit were prepared by mixing polymer with
60/70 penetration grade (PG58-22) base bitumen. The rheological properties of modified bitumen at high
temperatures were measured using dynamic shear rheometer and the viscosity of the bitumen was
evaluated using Brookfield Rotational viscometer .The results indicated that by increasing the Sasobit®
content, the performance of modified bitumen has considerable improvement at high temperature, so that
the upper limit of bitumen’s performance grade has ascended from 58 to 70 for the Sasobit® modified
bitumen containing 4% Sasobit®.
