TANK FOR KEEPING ASPHALT MIXTURE WARM

摘要

PURPOSE: A thermal insulating tank of asphalt mixture is provided to repair a road efficiently by keeping manufactured asphalt for a long time, and to improve the endurance of the road by increasing stability and abrasion resistance with heating asphalt mixture at the optimal temperature. CONSTITUTION: A constant temperature asphalt tank is composed of a case(12) storing asphalt mixture; a lid(14) combined with the upper part of the case; a thermal insulating material mounted at the side of the case to keep the asphalt mixture warm; a heating unit(18) heating the asphalt mixture out of the case; a flue(20) installed in the edge of the case to guide combustion gas from the heating unit and transmit heat to the case; plural temperature sensors(22,24) detecting the internal temperature of the case and the temperature of the flue; and a control unit(26) receiving the detecting signal from the temperature sensors and controlling the heating unit. The asphalt mixture is transported promptly with being stored in the tank in repairing the road, and heated in the case for pavement of the road. The remaining asphalt is contained in the tank after repairing the road.
