Method for reducing low-temperature cracking of asphalt pavement
The invention provides a method for reducing low-temperature cracking of an asphalt pavement, and belongs to the technical field of highway engineering. According to the method, the asphalt pavement is subjected to joint cutting, and the proper joint cutting distance is determined to adjust the stress of the asphalt pavement, so that the cracking of the asphalt pavement at low temperature is reduced. The result of the embodiment shows that compared with the non-kerf asphalt pavement, the low-temperature cracking phenomenon of the asphalt pavement with the kerf spacing of 27.9 m is basically eliminated, the low-temperature cracking phenomenon of the asphalt pavement with the kerf spacing of 40 m is reduced by 10%, the low-temperature cracking phenomenon of the asphalt pavement with the kerf spacing of 5 m can also be eliminated, and the low-temperature cracking phenomenon of the asphalt pavement with the kerf spacing of 27.9 m is reduced by 10%. However, the construction cost is increased.
本发明提供了一种减小沥青路面低温开裂的方法，属于公路工程技术领域。本发明在沥青路面进行切缝，并确定合适的切缝间距以调整沥青路面应力，从而减小沥青路面在低温时的开裂。实施例的结果显示，采用本发明方法处理后，与未切缝沥青路面相比，切缝间距为27.9m的沥青路面低温开裂现象基本得到消除，而切缝间距为40m的沥青路面低温开裂现象减小了10％，切缝间距为5m的沥青路面低温开裂现象也能得到消除，但其增加施工成本。
