Disposal method for arch expansion crack of asphalt pavement
The invention relates to a treatment method for an arch expansion crack of an asphalt pavement. The asphalt pavement comprises an asphalt pavement structure and a pre-cutting joint; the asphalt pavement structure comprises a structural layer and a base layer, the structural layer is divided into an upper surface layer and a lower surface layer, the upper surface layer is made of modified asphalt concrete, the lower surface layer is made of asphalt concrete, and the structural layer is arranged above the base layer; the pre-cutting seam is arranged on the base layer; calculating a temperature drop allowable value and a temperature rise condition under which a base layer does not crack according to the influence of parameters of temperature and humidity, and preventing the asphalt pavement from cracking according to temperature limitation; the invention aims to solve the technical problem of pavement cracking caused by temperature difference in the prior art.
本发明涉及一种沥青路面拱胀裂缝的处置方法，沥青路面包括沥青路面结构和预切缝；所述沥青路面结构包括结构层和基层，所述结构层分为上面层和下面层，上面层为改性沥青混凝土，下面层为沥青混凝土，所述结构层设置在所述基层上方；所述预切缝设置在所述基层；通过温度、湿度的参数影响，计算出温度降允许值和基层不开裂的温升条件，根据温度限制预防沥青路面开裂；本发明的目的是为了解决现有技术中存在温度差导致路面开裂的技术问题。
