Study of temperature loss of Hot Mix Asphalt during transportation

Abstract

This study was conducted to observe the phenomenon of the temperature loss on hot mix asphalt type Asphalt Concrete Binder Course (AC-BC), on the surface area of the truck wall during transport. The tests were conducted experimentally using thermometers and thermocouples with a 25-ton capacity truck at 153°C loading temperatures. Data retrieval is carried out over time, 20.40,60 to 420 minutes of transport, from the Asphalt Mixing Plant (AMP) plant to the job site with an average truck speed of 30 km/h. Data from the results of the study were analyzed using the descriptive method. The results indicate that the maximum transport distance that meets the technical specifications is at the furthest distance of 165 km, with a minimum temperature of 130,1°C, at a distance of 10 cm from the surface of the truck wall. Loss of average hot mix asphalt temperature to 6 (six) sides of the truck wall surface, floor surface and the top surface, for 420 minutes of transport is (45.2°C-65.7°C). From the phenomenon shows that the hot mix asphalt condition on the surface area of the truck wall is hardened (crusty).
