Drainage asphalt pavement pre-maintenance material and construction process thereof
The invention provides a drainage asphalt pavement pre-maintenance material and a construction process thereof. The drainage asphalt pavement pre-maintenance material comprises high-viscosity and high-elasticity modified asphalt, a viscosity reducer, a diluent and a foaming agent. The construction process comprises the following steps: heating the high-viscosity high-elasticity modified asphalt toa certain temperature, sequentially adding the viscosity reducer and the diluent, and uniformly stirring the same; using an asphalt automatic spraying vehicle to implement operation on the drainage asphalt pavement, adding the foaming agent into the mixed modified asphalt before spraying, after uniform stirring, conducting spraying operation according to a certain spraying amount, and after curing is conducted for a period of time, completing the construction. The high-viscosity high-elasticity asphalt is used as a main component of a pre-maintenance material, and after pre-maintenance operation, exposed stones on the surface of an old pavement are good in wrapping effect, the interface bonding effect of new asphalt and old asphalt is good, the pavement water seepage capacity loss is small, the pavement friction coefficient is remarkably improved, the engineering service life is expected, the construction process is fast, and the generalizability is high.
本发明提供了一种排水性沥青路面预养护材料及其施工工艺，所述排水性沥青路面预养护材料包括高粘高弹改性沥青、降粘剂、稀释剂、发泡剂。其施工工艺为：加热高粘高弹改性沥青至一定温度，依次加入降粘剂、稀释剂，搅拌均匀；采用沥青自动喷洒车辆在排水性沥青路面上实施作业，喷洒前将发泡剂加入上述混合后的改性沥青中，搅拌均匀后，按照一定的喷洒量进行喷洒作业，养生一段时间后，施工完成。本发明以高粘高弹沥青为预养护材料主要成分，预养护作业后，旧路面表面裸露石料裹覆效果好，新旧沥青界面结合效果好，路面渗水能力损失小，路面摩阻系数提高显著，工程寿命达到预期，施工工艺快捷、可推广性强。
