- Abstract
Urban floods are a frequent disaster in Indonesia and cause road damage with the relatively high cost of repairs every year. Durability test of water damage of asphalt mixture on mild temperatures, such as indirect tensile test did not show the weakness of asphalt mixture. Therefore, this study aims to use an elastic modulus ratio, which is the result of an unconfined compressive strength test, as an indicator of the water damage of asphalt mixture. Five types of aggregate gradations of asphalt concrete wearing course and AC 60/70 asphalt at optimum bitumen content were selected. The specimen was treated with three conditions of aging, namely no aging, short-term oven aging and long-term oven aging. Immersion conditioning was carried out of 0, 1, 2, 4 and 7 days at 25 °C. Selokan Mataram Yogyakarta water in the rainy season was used as a medium attack. This study proposed equivalent retained strength of elastic modulus as the durability indicator of the asphalt mixture. The results show that elastic modulus can assess the effect of water damage on asphalt concrete, aging of asphalt concrete has a significant effect at more than 4 days immersion, and the optimum gradation of flood water resistance has Gradation Index 21.53-27.29%.
