在沥青混合料转运过程中,应用保温运输车对其进行加热,可以保持沥青混合料合理温度。为保证沥青混合料温度均匀性,防止沥青老化,目前普遍采用导热油对沥青混合料进行加热。采用导热油加热沥青混合料,可实现低压运行,可获得较高温度,易于自 In the asphalt mixture transfer process, the application of insulation transport vehicles to be heated, can maintain the reasonable temperature of asphalt mixture. In order to ensure the uniformity of temperature of asphalt mixture and prevent the aging of asphalt, heat conducting oil is commonly used to heat asphalt mixture. The use of heat-conducting oil heating asphalt mixture, enabling low-voltage operation, access to higher temperatures, easy to self
