This paper studies the performance of HMA containing aggregate from Sargodha city of Pakistan. The
AASHTO T-283 is the most widely used test for evaluating moisture susceptibility and is based on comparing tensile
strength ratios. In the first step, the optimal bitumen content was determined. The optimal binder content was determined
by optimization of different factors that affect the performance of the asphalt mixture. In the second step, the 7 ± 1% air
voids were maintained. Finally, AASHTO T-283 was used to measure the damage in the asphalt mix caused by the
moisture. The asphalt samples were evaluated in dry and wet states. The results of the test would be helpful in
understanding the performance of the binder and local aggregates for the moisture susceptibility.
