This paper reports the investigation results of hot mix asphalt compacted at rain water simulation (HMA-CARS). Objectives of the research are to analysis the characteristics of HMA-CARS and reclaimed HMA-CARS after certain treatments. Research method was developed through the two main programs. First, is to investigate the characteristics of hot mix asphalt compacted using roller slab with water spraying. Second, is to investigate the characteristics of reclaimed HMACARS with developing three alternatives treatments. The results can be described in two main points. First, due to water spraying during compaction process, the performance of HMA-CARS decrease and does not meet the general specification of Bina Marga 2010. Second, the performance of reclaimed HMA-CARS can be improved by the treatments; however it cannot help the reclaimed mixture to meet the specification requirements.
