Abstract

A heater for thermally regenerating the asphalt pavement by direct radiation heating to repair and maintain the asphalt pavement is composed of an air heating boiler, a circulating blower, a heating box with several rows of spray holes and suspended under said boiler, a lifting mechanism, and several telescopic heating tubes with spray holes and connected between heating box and telescopic mechanism. Its advantages are high heat efficiency and saving fuel.

Description

technical field [0001] The invention relates to special equipment for asphalt pavement repair and maintenance. Background technique [0002] The traditional way of repairing and maintaining the pavement is to use asphalt mixture and provide it from the asphalt mixing plant, and transport it with a special heat-insulating and heating transport vehicle. This method is limited by time and space. Using traditional methods to repair and maintain pavement has the disadvantages of low work efficiency, high energy consumption, and long construction preparation time. At the same time, it has the disadvantages of poor construction flexibility and strong dependence on asphalt mixing plants. The traditional way of heating asphalt mixture is to directly heat the asphalt. The heating quality is poor, causing serious pollution to the environment. Now there is an in-situ thermal regeneration heating method for damaged asphalt pavement to improve the traditional method, but in actual oper...
