Reflection-resistant asphalt pavement crack treatment method and construction process thereof
The invention discloses a reflection-resistant asphalt pavement crack treatment method and a construction process thereof, cracks are treated by comprehensive measures, and the main technical principle is that grouting is performed to improve the structural strength of the pavement, an anti-crack paste is laid at the bottom of a cutting groove, and then fatigue-resistant asphalt concrete is poured. According to the method, the fatigue life of transverse cracks and reflection crack inhibition of the asphalt mixture layer is more than 5 times that of a conventional method, cracks can be effectively sealed, and reflection cracks do not appear in general expressways within 5 years.
本发明公开了一种耐反射的沥青路面裂缝处治方法及其施工工艺，采用综合措施处治裂缝，主要技术原理是注浆提升路面结构强度、切槽底部敷设抗裂贴，然后浇注耐疲劳沥青混凝土。本发明处治横向裂缝，沥青混合料层抑制反射裂缝的疲劳寿命是常规方法的5倍以上，能有效封闭裂缝，一般高速公路5年内不出现反射裂缝。
