Marshall Characteristics in Asphalt Concrete – Wearing Course (AC-WC) in Various Length and Temperature Submersion

Early damage of road pavement in Indonesia is commonly caused by weather and water submersion. The road pavement performances, i.e. road strength and durability, are affected by the existing of water submersion and the load through the road. By using Marshall Test, the research aims to find out the effect of submersion to the Asphalt Concrete–Wearing Course (AC-WC) characteristics, i.e. stability, flow, Marshall Quotient (MQ), Void in Mix (VIM) and Void in Mixed Aggregate (VMA) with 60/70 asphalt penetration and 6.1% asphalt content while submerged in water bath. The durations of submersion are 1×24, 2×24, 4×24, 6×24 and 8×24 hours in various temperatures that are 32, 50, 60, 70 and 80 °C. The mixing asphalt consists of Coarse Aggregate (CA), Medium Aggregate (MA) and Fine Aggregate (FA). Moreover, this experiment is done under Bina Marga specification. As the result, this research shows that the length and temperature of submersion influenced the Marshall Strength of asphalt AC-WC. The duration of AC-WC submerged in water has affected its strength and durability shown by the decreasing of Marshall Value. Also, it occurs when the temperature of submersion was increased.
