Abstract
Pavement rutting is one of the most common and destructive pavement distresses being observed
in flexible pavements, which is primarily due to axle loads that exceed legal limit and high ambient
temperatures, and also poor mix design is one of the cause of rutting. The drastic increase in traffic
volume during last few decades has resulted in premature pavement failures of almost the whole road
structure in Pakistan. In this scenario it is the time to investigate this problem and propose
appropriate solution. Physical properties of aggregates and bitumen were evaluated in the laboratory.
Mechanical Properties of three mixes, i. e., Marshall, Superpave and Stone Mastic Asphalt (SMA)
were evaluated by performing creep test, indirect tensile test and dynamic modulus in order to
compare the performance of mixes under prevailing load and environmental conditions of Pakistan.
The study revealed that Superpave mixes performed better than Marshall and SMA.
