Construction method for deeply processing reflective cracks on asphalt pavement

Abstract

The invention provides a construction method for deeply processing reflective cracks on an asphalt pavement. The method can be simply operated onsite; a material is general, so the construction cost is saved, a large amount of mechanical devices or labor, excavation of pavements or bases and long-term closed traffic are avoided, and the construction period is greatly shortened; and a geopolymer grouting material is filled, so the overall construction quality is improved. The method achieves the purposes of shortening the construction period, reducing traffic impact, reducing labor input and improving the construction quality, and solves the problems of long construction period, serious pavement pollution, long closed traffic time and poor processing effect of conventional methods, needingclosed traffic to excavating and afresh lying surfaces and bases or excavating the surfaces and grouting the bases or below, for processing reflective cracks on the asphalt pavement.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for deeply treating reflective cracks on asphalt pavement. Background technique [0002] Asphalt concrete pavement has many advantages over pure concrete pavement, and is more and more applied to high-grade highways. At present, with the increase of highway traffic volume, heavy-duty vehicles and overloading are very serious, and are affected by various environmental factors such as road structure, climate, terrain, geological conditions, and driving loads. Whether the base layer is flexible or semi-flexible Rigid ones will produce cracks of different degrees and shapes. When the cracks continue to expand upward, reflection cracks will be formed. [0003] Conventional methods to deal with reflective cracks on asphalt pavement are to excavate the surface layer and the base layer to re-pave, or to remove the surface layer and then grout the b...

Problems solved by technology

[0004] The purpose of the present invention is to solve the conventional method of processing asphalt pavement reflective cracks proposed in the above-mentioned background technology, which is to dig out the surface layer and the base layer to re-pave, or to break the surface layer and then carry out grouting to the base layer and below. The above methods all need Interruption of traffic, long construction period, serious road pollution, long time of traffic closure, and poor treatment effect;
