Abstract
Granite is the commonly used natural aggregate in asphalt concrete (AC) and it make up about 75% to 80% by volume. Due to rapid infrastructure development and road construction in Sarawak, the available material such as granite is depleting rapidly. Sarawak has rich sub-standard aggregate resources and there are possibilities that certain sub-standard aggregate such as limestone and microtonolite can be used to replace granite. The research involved the formulation of the mix proportion of AC consisting limestone and microtonolite as the aggregates, the evaluation of the mechanical performance of AC consisting limestone and microtonolite, as well as the comparison of the properties and performance of both types of AC with JKR standard. Laboratory experiments were conducted in accordance to ASTM standards in this paper to evaluate the suitability of sub-standard aggregates such as limestone and microtonolite to replace granite in flexible pavement construction. Based on the tests conducted, the physical and mechanical properties of limestone achieved the minimum requirements whereas microtonolite exceeded the maximum water absorption as stated in JKR standard requirement. This research also found that the engineering performance of limestone aggregate complied with all the specified requirements in JKR standard specification to be used in AC.
