【 摘 要 】

Indonesia has been extensively expanding its road networks to support the economic and the population growth. It is very important to ensure that the road networks perform well and last to their designed life. However, it is very common to find roads with asphaltic surfaces with some pavement failures not long after the construction finished. The most commonly pavement failures found are potholes and stripping, which are related to water intrusion to the hot mix asphalt. Indonesia is a tropical country and its soil has a high groundwater level in general. Therefore, it is very important to study the effect of moisture in asphaltic surfaces. This research aims to provide a preliminary analysis on the moisture susceptibility of hot mix asphalt. It was found that there were a few of Marshall test results that did not satisfy the requirements, which could be caused by human variation and the angularity of aggregates. The Cantabro Loss test results show that the HMA specimens lost around 11% and 15% of material after being exposed to water and abraded. From the research results, it was found that there is a strong relationship between the flow and the Cantabro Loss of the prepared HMA specimens.
