The increasing of road material demand particularly on aggregate has been follow-up by finding the new alternative materials. Local materials such as Bantak and Clereng are potentially to substitute current need. Apparently Bantak is having high porosity and abrasion value more than 40%, on other hand Clereng is giving lower abrasion value (< 25%) than Bantak. Therefore, it is essential to study the performance and durability of these materials in AC-WC mixture. To find the durability index, the specimens are immersed around 0 (unconditioned) to 14 days at 60oC and tested by using Marshall and ITS. From the Marshall test, the index values for aggregate variations I, II, and III are 35.01%, 28.11%, and 26.10% respectively, while from ITS test, the indexes are 33.70%, 27.97%, and 25.45% respectively. The best result is variation III as the lowest value because has less of Bantak, which means less porosity and water absorption.
