Abstract

The aggregate types and gradations play an important role in determining the performance and the rutting and cracking behavior of bituminous mixture. Two different aggregate types is compared which are granite and limestone, while the gradations comparison is between well graded and gap graded aggregate. The material physical properties laboratory tests proved that granite aggregate is stronger and durable than limestone aggregate. From Marshall Analysis results, it shows that granite and well graded mixtures require less amount of optimum bitumen content as compared to limestone and gap graded mixtures. The rutting behavior was evaluated using Dynamic Creep Test and Wheel Tracking Test while cracking behavior was evaluated using Beam Fatigue Test. From the results of all tests that have been conducted, the outcomes shows that the combination of granite and well aggregate gradation can provide an excellent rutting and cracking resistance. This shows that both aggregate types and gradations play important role in bituminous mixture performance.
