Non-full-thickness cement pavement overlay material and construction process thereof
The invention discloses a non-full-thickness cement pavement overlay material and a construction process thereof, the non-full-thickness cement pavement overlay material is composed of basalt, shape memory particles, limestone mineral powder and high-elastic modified asphalt, and the non-full-thickness cement pavement overlay material can improve the crack resistance of a stress absorption layer, delay longitudinal reflection cracks of a pavement and prolong the service life of the pavement. The construction process comprises the following steps: carrying out finish milling treatment on a cement pavement, and forming a groove in the surface of the pavement; uniformly spraying an interlayer high-strength binder on the whole pavement; and then a non-full-thickness cement pavement overlay material is spread on the interlayer high-strength binder to serve as a stress absorption layer, the pavement structure can reduce the consumption of building materials such as stone and asphalt for pavement overlay by about 30%, and the pavement structure has remarkable environmental protection benefits and economic benefits. And finally, after the construction of the additional paving material of the non-full-thickness cement pavement is finished, a wearing layer with the thickness of 4-5cm is constructed on the upper layer of the non-full-thickness cement pavement, so that the wear resistance of the surface layer is effectively enhanced, the service life of the pavement is prolonged, and the driving comfort and safety can also be improved.
本发明公开了一种非全厚式水泥路面加铺层材料及其施工工艺，该非全厚式水泥路面加铺层材料由玄武岩：形状记忆颗粒：石灰岩矿粉：高弹改性沥青组成，其能够提高应力吸收层的抗裂性能，延缓路面纵向反射裂缝，提高路面使用寿命。该施工工艺为对水泥路面进行精铣刨处理，并且使得道路表面形成凹槽；在整个路面上统一洒布层间高强粘结剂；而后在层间高强粘结剂上层撒铺非全厚式水泥路面加铺层材料作为应力吸收层，该铺装结构能够减少路面加铺对石料、沥青等建筑材料的消耗约30％，具有显著的环保效益和经济效益；最后在非全厚式水泥路面加铺层材料施工完成后，在其上层施工4‑5cm厚磨耗层，有效的增强表面层耐磨耗性，延长路面的使用寿命，还可以提高行驶的舒适性及安全性。
