Problems solved by technology

The quality inspection of the physical project is inseparable from the process of construction, inspection, or operation and maintenance of highways. Core quality control indicators such as the thickness of the structural layer and the degree of compaction of the pavement are inspected by coring. However, the coring inspection is a destructive inspection. If If the test hole is not filled in time or not densely filled, it will easily lead to early diseases such as water seepage, pumping, and pits on the asphalt pavement

Embodiment Construction

[0032] like Figure 1 to Figure 4 Shown, a kind of filling material, equipment and method for asphalt pavement coring test hole, including test hole filling material 1, funnel 31 and tamping rod 4, test hole filling material 1 is super toughness quick setting cement concrete, test hole Filling material 1 is made by mixing aggregates, yellow sand, cement, rubber particles, water, early strength agent and expansion agent in proportion. Ordinary Portland cement P.O42.5 or P.O32.5, the yellow sand is medium-coarse sand, the fineness modulus is 2.3-3.0 or 3.1-3.7, and the expansion agent is 80-85% of natural anhydrous gypsum, natural It is a combination of 10% alum stone and 5-10% calcined coal gangue. The bulking agent can moderately expand the cement concrete to reduce the volume shrinkage of the concrete, fully fill the gap between the asphalt concrete and the cement concrete, and achieve compactness and compactness. The role of water.

Abstract

The invention provides a filling material for a bituminous pavement coring test hole, and particularly relates to the technical field of pavement engineering repair. A test hole filling material, a funnel and a tamping rod are included. The test hole filling material is super-toughness quick-setting cement concrete, the test hole filling material is prepared by mixing aggregate, yellow sand, cement, rubber particles, water, an early strength agent and an expanding agent in proportion, a fixing frame is arranged on the funnel, the upper end of the fixing frame is connected with the outer side wall of the funnel, and a handle is arranged on the fixing frame. According to the filling material, equipment and method for the bituminous pavement coring test hole, a test hole filling operation behavior is standardized, and early-stage pavement diseases caused by a test hole filling link are avoided so that the comprehensive performance of a bituminous pavement is improved, the service life of the bituminous pavement is prolonged, and remarkable economic benefits and social benefits are generated.

Description

technical field [0001] The invention belongs to the technical field of road surface engineering restoration, and in particular relates to a filling material, equipment and method for asphalt pavement coring test holes. Background technique [0002] Highway construction is the main way of national development strategy. In order to adapt to social development and further improve people's travel safety and driving comfort, more than 95% of my country's grade highways have been built with asphalt pavement. The quality inspection of the physical project is inseparable from the process of construction, inspection, or operation and maintenance of highways. Core quality control indicators such as the thickness of the structural layer and the degree of compaction of the pavement are inspected by coring. However, the coring inspection is a destructive inspection. If If the test hole is not filled in time or not densely filled, it will easily lead to early diseases such as water seepag...
