Embodiment

[0027] Embodiment: The semi-rigid base road surface disease detection and high polymer grouting maintenance technology of the present invention include the following contents:

[0028] 1. A semi-rigid base pavement disease detection method

[0029] (1) Semi-rigid base pavement defect detection technology based on falling weight deflectometer (FWD):

[0030] 1) Use FWD to conduct deflection test on the selected road section;

[0031] a. Load setting: generally set to 10 tons;

[0032] b. Measuring point location: Generally, it is selected at the wheel track, and the distance between measuring points is 6m; if there is a crack, arrange points on both sides of the crack, and the measuring point is 30cm away from the crack.

[0033] 2) Based on the FWD deflection test data, the structural layer modulus is back calculated by using the mechanical property back calculation software SIDMOD;

[0034] 3) Judging the disease condition according to the modulus inverse calculation resul...

Abstract

The invention discloses a semi-rigid base pavement damage detection and polymer grouting fast maintenance method based on a falling weight deflectometer (FWD) and a ground penetrating radar (GPR) non-destructive test, which detects and evaluates the performance of the pavement and judges the semi-rigid base pavement damage condition by using the FWD and GRP. A grouting hole is perforated on the section that needs damage treatment and polymeric materials are injected into the hole to repair the pavement. The injected polymer material can be filled automatically during the expansion to reinforce loose area or soft area.

Description

technical field [0001] The invention belongs to roadbed pavement detection and maintenance technology, in particular to semi-rigid base road surface disease detection and high polymer grouting rapid maintenance technology. Background technique [0002] At present, my country's high-grade highway construction is in a stage of rapid development. As one of the main pavement types of high-grade highways, semi-rigid base asphalt pavement is the most widely used in my country's high-grade highways, accounting for more than 75%. However, due to various reasons, many road surfaces cannot meet the needs of vehicle traffic soon after they are built, and various early damage phenomena have occurred. It can be predicted that in the near future, the focus of my country's highway construction will shift from construction-based to construction and maintenance simultaneously, and will develop in the direction of maintenance-based. Therefore, the specific development environment and object...
