Abstract

The purpose of this paper is to grasp effect of flood puddle to durability of asphalt concrete mixture on road pavement. In this regard, an experimental study was carried out by using Modified Immersion test in order to represent the flood phenomenon and Marshall Immersion test as reference. The experimental treated immersion test during 1, 3, 5, and 7 days to the two types of asphalt mixture, i.e. the mixture containing Retona additive and uncontaining it. The research adopted three types of durability indexes to describe asphalt mixture durability, i.e. the retaining strength index (RSI), the first durability index (FDI), and the second durability index (SDI). The results show that Modified Immersion test gave good appearance to grasp deterioration of the mixtures durability due to flood puddle during some days. In further, the asphalt concrete mixtures still retained until seven days immersion, where the mixture containing Retona was more durable than the other mixture.
