Study on Heat Loss through Dump Truck Wall Insulated by Sengon Wood

Abstract

The quality of road construction using hotmix asphalt is determined by the temperature at the time of compaction. The distance or duration of transportation from the Asphalt Mixing Plant (AMP) plant to the work site causes temperature loss during the trip, especially near the truck wall. As a result of this phenomenon, the temperature available at the time of compaction is decreasing, so that the temperature does not meet the required technical specifications. One way to protect the rate of hot mix asphalt temperature loss is by adding sengon wood insulation to the truck wall so that the temperature does not go out into the air environment. The insulating material used is sea sengon wood, because it has a low thermal conductivity value. The purpose of this work is to study the phenomenon of hot mixasphalt temperature loss rate on the effect of using sengon wood as insulation on the walls of trucks during transport. In this study, the test was carried out as an Asphalt Concrete Binder Course (AC-BC) using a 25-ton intercooler truck, carried out experimentally by measuring the temperature at the specified points for 420 minutes from the AMP factory to the dumping location. From the test results showed that the temperature of the hot mix asphalt near the truck's floor and wall averaged an initial temperature of 102.78⁰C until the average spread location was 91.48⁰C. The temperature of the truck's center zone is relatively stable during transport, from loading 145⁰C and end 143.7⁰C, the temperature available for deployment still meets the required technical specifications.
