Abstract:Based on the pit-groove repair technology of the new-type mesh sealing anti-cracking structural material, combined with the analysis and application of the typical pit and groove diseases on the asphalt pavement of a heavy-duty expressway, the construction process of the new-type mesh sealing repair technology is proposed. According to the research on material testing and application tracking testing, it is found that the key material of the new-type mesh sealing anti-cracking structural material of the technology has the significant advantages in pull-out performance, shear performance and water damage resistance compared with the use of traditional geotextile materials. This technology has the advantages of convenient implementation and good durability, and has good applicability for expressways with heavy traffic, which also provides a reference for the transformation of the idea of pavement maintenance technology from breaking through single material modification to realizing comprehensive structural improvement.
