[0002] During the construction of asphalt pavement in highway projects, tack coat oil is usually spread between adjacent asphalt surface layers to make the two layers adhere to each other as a whole. At present, emulsified asphalt is mostly used as tack coat oil in China, which breaks into an oil film after being spread.
[0003] However, in the actual construction process of the existing asphalt mixture paving machine, due to the serious phenomenon of the tack layer material sticking to the wheel, the bonding material is lost in the wheel track, which reduces the bonding effect, thus affecting the durability of the road surface, resulting in reduced adhesion between the asphalt pavement layers, causing pavement diseases such as shifting and bumping. The discontinuity of maintenance work in actual operation exacerbates this phenomenon, resulting in frequent early disease phenomena and seriously shortening the life cycle of the maintenance project.
