Description

technical field

[0001] The invention relates to the field of road engineering, in particular to a quick repair method for asphalt pavement cracks. Background technique

[0002] Cracks have become one of the most important early diseases of asphalt pavement, which seriously endangers the performance and service life of asphalt pavement. However, the existing crack repair methods are mainly limited to cutting and glueing, that is, cutting U-shaped joints and pouring hot asphalt , After sealing the cracks, prevent moisture from entering the interior of the pavement structure along the cracks. However, the low strength of the potting material cannot prevent the opening cracks from spreading upward under the action of the load, and the joint potting material cannot effectively bond the pavement structure on both sides of the crack due to the external environment, and the cracks will be re-formed quickly under the action of the traffic load. The joint glue falls off and needs to ...
