Analysis of the Temperature Drop of Hot Mixed Asphalt during the Trip to the Overlay Site (Case Study: Keude Linteung–Meulaboh)

Hot mix asphalt consists of a mixture of coarse aggregate and fine aggregate with asphalt binder that has certain requirements and is heated to a certain temperature. In the process of delivering hot mix asphalt, there is a temperature drop of hot mix asphalt when it arrives at the overlay site. The purpose of this study was to determine the characteristics of the temperature drop on hot mix asphalt during the trip to the overlay site. The research method is experimental method will be used on a hot mix asphalt transport truck. The temperature measurement was carried out 5 minutes after the asphalt was poured into the truck and while on the way to the overlay site with a measurement time span of 0, 30, 60, 90 and 120 minutes. The results of the study showed that a very significant drop in the temperature of hot mix asphalt occurred in transport trucks 2 at points T4 and T6, namely the initial temperature of each 150°C to the final temperature of 139°C. The transport of truck 1 the temperature drop of hot mix asphalt that occurs is 10 °C the largest and on transport truck 2 the maximum temperature decrease for hot mix asphalt that occurs is 11 °C. Before shipping the hot mix asphalt, the weather should be considered in order to minimize temperature drop of hot mix asphalt that occurs.
