在道路施工过程中,沥青混合料的温度能够直接影响施工质量、道路使用寿命以及施工工艺的合理性。沥青混合料保温运输车可以在沥青混合料转运工程中对沥青混合料进行加热,以保证沥青混合料合理的温度。目前常用的加热方式有液化石油气加热保温和电加热保温两种,分析了两种加热方式的实用性及经济性,并对比得出两种加热方式的优缺点。 In the process of road construction, the temperature of asphalt mixture can directly affect the construction quality, road life and construction process rationality. Asphalt mixture insulation truck can be asphalt mixture in the transport of asphalt mixture to be heated to ensure that the asphalt mixture at a reasonable temperature. At present, there are two commonly used heating methods: heating liquefied petroleum gas (LPG) and electric heating insulation. The practicality and economy of the two heating methods are analyzed. The advantages and disadvantages of the two heating methods are compared.
