Asphalt concrete as a wear layer, known as the Asphalt Concrete-Wearing Course (AC-WC) with a minimum nominal thickness of 4.0 cm. However, the use of AC-WC layers in the pavement structure is often faced with problems of performance degradation due to the development of various types of damage during the service life one of them is a result of the effect of water. In general, water has a negative effect on road pavement construction. Standing water can be caused by high rainfall, poor drainage systems, high groundwater levels, and water runoff. This research aims to look at the performance of the physical and mechanical properties of testing Marshall characteristics on a mixture of asphalt pen 60/70 wear layer (AC-WC) on the duration of water immersion from three different types of water. The specimen was carried out immersion testing from three types of water, namely clean water, brown flood water and black air with 30 minute immersion standards with variations of 1 day, 7 days, 14 days, 21 days and 30 days. The study outcomes shows several conclusions: (1) From the Marshall test results the physical properties obtained showed that the longer the immersion time the greater the VIM value obtained, the increase occurred in the type of brown flood water with the lowest Ph. Whereas the value of VFB in brown flood water immersion decreased the most as the duration of the immersion; (2) The mechanical properties of the Marshall test results are stability values still meet the standards, while for the value of melt and MQ black flood water immersion is the most influential on the asphalt mixture.
