Asphalt pavement crack embedded repairing method
The invention discloses an asphalt pavement crack embedded repairing method, and belongs to the technical field of asphalt pavement construction. The method comprises the following steps of: after expanding a crack, uniformly digging a plurality of fusion embedding holes in two side walls in the crack through molten asphalt by using a hole embedding tool, and reserving pre-embedded magnetic ballsin the fusion embedding holes; then preparing a joint sealing material on site, mixing a proper number of chemical force soft rods to be injected into the cracks after being mixed to be uniform, forcing the chemical force soft rods to partially enter the fusion embedding holes to be combined with the pre-embedded magnetic attraction balls through the magnetic attraction effect of the pre-embeddedmagnetic attraction balls on the chemical force soft rods, and foring high-strength combination of the cracks and an original asphalt pavement after the joint sealing material is cured; when the crackis extruded, the downward pressure of the chemical force soft rod is converted into the extrusion of the pavement on the two sides of the crack to the center, so that the pressure can be effectivelycounteracted, secondary cracking at the crack can be prevented, and the crack repairing strength is greatly improved.
本发明公开了一种沥青路面裂缝嵌入式修补方法，属于沥青路面施工技术领域，本发明可以通过在对裂缝扩缝后，通过嵌孔工具在裂缝内两侧壁上通过熔化沥青均匀开凿出多个熔嵌孔，并于熔嵌孔内预留下预埋磁吸球，然后现场制备出补缝材料并混入合适数量的化力软棒，混合均匀后注入至裂缝中，依靠预埋磁吸球对化力软棒的磁吸作用，迫使化力软棒部分进入到熔嵌孔内与预埋磁吸球结合，在补缝材料固化后形成裂缝处与原沥青路面的高强度结合，在裂缝处受到挤压时，利用对化力软棒向下的压力，转化为裂缝两侧路面向中心处的挤压，不仅可以有效抵消压力，同时可以防止裂缝处出现二次开裂，实现裂缝修补强度的大幅提升。
