Construction method for preventing reflection cracks of semi-rigid pavement
The invention relates to a construction method for preventing reflection cracks of a semi-rigid pavement, and belongs to the technical field of road construction.According to the construction method, the surface of a water-stable macadam base is treated through a pre-impregnating agent, the porosity of the water-stable macadam base is reduced, surface layer air holes are closed, and the waterproofness of the water-stable macadam base is improved; a continuous reinforcing net is formed on the surface layer to influence the capillary action, so that the shrinkage stress in the water-stable gravel is reduced, the generation of initial cracks is prevented, and the strength and toughness of the water-stable base layer are improved; according to the invention, heat treatment is carried out on the pre-impregnating agent through the temperature during paving of the asphalt layer, and heat energy freely dissipated during paving in the past is utilized, so that the energy utilization rate is improved, and construction is more convenient.
本发明涉及一种防止半刚性路面反射裂缝的施工方法，属于道路施工技术领域，本发明通过预浸渍剂对水稳碎石基层表面进行处理，降低了水稳碎石基层的孔隙率，封闭了表层气孔，提高了水稳碎石基层的防水性；并在表层形成了连续的增强网，影响毛细管作用，从而减少了水稳碎石内的收缩应力，防止初始裂缝的产生，提高了水稳基层的强度和韧性；本发明通过沥青层摊铺时的温度对预浸渍剂进行热处理，利用了以往摊铺时自由散发的热能，不仅提高了能量利用率，也更方便施工。
