Abstract

The invention provides an organic modified reinforcement and strengthening road surface material and a preparation method thereof. The organic modified reinforcement and strengthening road surface material is prepared by the following raw materials: sand, a mineral powder mixture, a composited alkaline exciting agent, an organic mixture, a fiber mixture, a composited dispersing agent and water. According to the organic modified reinforcement and strengthening road surface material prepared by the preparation method, the fiber mixture is added to the mineral powder mixture, used fibers are all natural, and environment-friendly and harmless; a palm fiber and a jute fiber have texture toughness, high elasticity and corrosion resistance and are decomposed into monofilaments under an alkaline condition, through mixing, the fibers are overlapped mutually to form a reticular three-dimensional structure to be evenly dispersed, and by using excellent bonding performance of the organic mixture, elastic nodes are formed, and a sheeted elastic material consisting of a plurality of plant fiber ''springs'' are formed in the organic modified reinforcement and strengthening road surface material. The organic modified reinforcement and strengthening road surface material is of great help in reducing road surface cracks, and can improve the crack resistance of a road surface.

Description

technical field [0001] The invention belongs to the field of road engineering materials, and relates to a grouting material, in particular to an organically modified and reinforced pavement grouting material and a preparation method thereof. Background technique [0002] With the rapid development of my country's road traffic industry, the quality requirements of road pavement structure have also been further improved, but the congenital defects in road design and construction, as well as the surge in traffic flow and axle load make municipal roads and highways often appear after a period of use. There are various structural damages such as subsidence, cracks, and grouting. At this time, the realization of pavement structure reinforcement is particularly important. Common pavement structure reinforcement technologies such as excavation reinforcement, cover reinforcement, etc., when applied to high-grade highways with heavy traffic, require long-term road closure construction,...
