Problems solved by technology

If maintenance and repairs are not carried out in time, its performance will decline rapidly, which will affect the fast, comfortable and safe driving of the vehicle.
However, if the original road surface is excavated on a large scale, there will be a long maintenance cycle and a large capital investment, which will also seriously affect the driving safety of the vehicle.

Embodiment Construction

[0035] A kind of asphalt pavement geopolymer grouting construction method, comprises the following steps:

[0036] (1) Construction preparation

[0037] Visual inspection of the asphalt pavement in the test section: there are many longitudinal and transverse cracks in the asphalt pavement, road rutting and other diseases: deflection detection of the asphalt pavement in the test section;

[0038] (2) Cloth holes

[0039] According to the grouting design, the grouting scheme adopts base grouting; the grouting holes are arranged in plum blossom pattern, and three rows of grouting holes are arranged in one lane, the grouting hole spacing is 1-2m, the row spacing is 1.5m, the hole diameter is Φ50mm, and the grouting holes There should be a release hole after the location is laid, and one release hole should be set for the four grouting holes, and the adjacent grouting hole can be used as the release hole; Hole position adjustment, the hole position adjustment spacing should be le...

Abstract

The invention discloses a geopolymer grouting construction method for asphalt pavement, which comprises the steps of construction preparation, hole layout, drilling, burying grouting pipes, grouting, pipe pulling, sealing, health preservation, testing and the like. The invention has convenient construction and good construction effect; the grouting process is environmentally friendly, low-consumption, economical and efficient, barrier-free, all-weather, and can be quickly opened to traffic, and can effectively solve the problem of insufficient bearing capacity of the foundation and the base, which makes the technology widely used on the road surface It has a broad application prospect in maintenance and repair and is worth promoting.

Description

technical field [0001] The invention relates to a grouting construction method of asphalt pavement geopolymer. Background technique [0002] At present, a considerable part of the road pavement put into operation in our country is close to or exceeds the design period. Although some have not reached the design period, some roads have been damaged to varying degrees under the influence of external conditions such as heavy traffic load and natural environment. , especially in the vicinity of intersections and bridge slopes, a large number of roads are in urgent need of reconstruction. If maintenance and repairs are not carried out in time, its performance will decline rapidly, which will affect the fast, comfortable and safe driving of the vehicle. However, if the original road surface is excavated on a large scale, there will be a long maintenance period and a large capital investment, which will also seriously affect the driving safety of the vehicle. In view of the above ...
