Description

Technical Field

[0001] The utility model belongs to the technical field of road base repair, and in particular relates to a geopolymer grouting structure for repairing road base. Background Art

[0002] In the process of highway construction and maintenance, semi-rigid base asphalt pavement has been widely used due to its excellent performance. However, due to factors such as thermal expansion and contraction, humidity changes, and the characteristics of the material itself, this type of pavement is prone to cracks during long-term use, especially reflective cracks, which seriously affect the performance and life of the road.

[0003] Traditional asphalt pavement crack repair technology mainly relies on surface caulking technology, using materials such as ordinary asphalt, emulsified asphalt, rubber asphalt sealant, etc. Although these materials can temporarily seal cracks to a certain extent, they are often difficult to achieve ideal repair effects due to poor adhesion to the original pavement materials, inconsistent deformation, and other issues, and are prone to secondary cracking, resulting in short-lasting repair effects and poor durability.

[0004] In recent years, with the progress of materials science and the development of engineering technology, geopolymer grouting technology has gradually been applied in the field of pavement repair. This technology injects geopolymer grouting materials into the cracks, so that the grouting materials are closely combined with the stones in the loose layer of the base layer to form a solid solidified bond state, thereby achieving the purpose of strengthening the base layer and improving the bearing capacity of the structural layer.

[0005] However, the traditional grouting method for crack repair has shortcomings in the arrangement of grouting holes and the control of grouting pressure. The traditional grouting hole arrangement is often limited to the middle of the crack, which makes it difficult for the grouting material to fully penetrate into the bottom of the base layer, resulting in poor repair effect. At the same time, improper grouting pressure control can easily cause the slurry to flow out along the gap and cannot be fully injected into the base layer.

[0006] Therefore, it is very necessary to invent a geopolymer grouting structure for repairing the pavement base. Utility Model Content
