自行式沥青洒布车广泛应用于新建及改扩建道路工程中的透层及粘层施工,以及道路养护工程中薄层罩面施工。沥青洒布车将沥青储存到其储罐内并运输到作业地点后,一般需要对其储罐内沥青进行加热处理。目前沥青洒布车对其罐内沥青的加热,普遍采用内置导热油加热或外置导热油炉加热2种方式,除此之外,我们探讨第三种加热方式,即利用发动机尾气余热进行加热。
Self-propelled asphalt spreader is widely used in new and expanded road construction in the layer and sticky layer construction, and road maintenance projects in the construction of thin-layer overlay. Asphalt trucks generally store asphalt in their tanks and transport them to the job site, generally requiring heat treatment of the asphalt in their tanks. At present, the asphalt sprinkling truck can heat the bitumen in the tank by using two methods: heating with built-in HTF or heating with an external HTF. In addition, we discuss the third heating method, that is, using the exhaust heat from the engine exhaust to heat .
