Cement concrete pavement curing agent and preparation method thereof

Abstract

The invention discloses a cement concrete pavement curing agent and a preparation method thereof and belongs to the related field of asphalt road maintenance and repairing. The curing agent comprises the following components in percentage by weight: 15 to 40 of refined asphalt, 10 to 30 percent of coal asphalt, 10 to 20 of epoxy resin, 20 to 40 percent of modifier, 3 to 15 percent of diluent, 0.5to 3 percent of aids, 3 to 10 percent of curing agent, and 10 to 30 percent of aggregate. The preparation method comprises the following steps of: shearing the refined asphalt, the coal asphalt, the epoxy resin, the modifier, the diluent, and the aids at the high speed at the temperature of between 100 and 120 DEG C for 60 to 90 minutes to form base stock A; and adding a curing agent (B) and aggregate (C) into the stock A, and uniformly stirring at normal temperature to obtain the curing agent. The curing agent has a simple preparation process, low equipment requirements, low using cost, and strong cement concrete seepage force, can be integrated with a pavement, and has the advantages of improving road appearance, sealing a road surface, prolonging the service life of a road and the like.

Description

technical field [0001] The invention relates to a cement concrete pavement maintenance agent capable of improving the performance of the surface layer of cement concrete pavement, sealing the pavement, improving the anti-skid ability of the road, and beautifying the pavement and a preparation method thereof, belonging to the related field of asphalt pavement maintenance and repair. Background technique [0002] Cement concrete pavement has the advantages of large bearing capacity, good stability, long service life, and low daily maintenance costs. It is now widely used in airport runways, expressways, trunk roads, urban roads, factory and mine roads, parking yards, and roads in tunnels. and waterways. However, its disadvantages such as long maintenance time, high cost, poor driving comfort, high noise and easy to raise dust are more and more unable to adapt to the development needs of modern roads. Especially in the past few years, cement pavement has been frequently used o...

AI Technical Summary

Problems solved by technology

For example, on the pavement inside the tunnel, after a period of operation of the cement concrete pavement, the anti-skid performance of the pavement will gradually attenuate, which brings great hidden dangers to driving safety. The processing method will increase the height of the road surface and reduce the clear height of the tunnel, which will affect the passage of large vehicles

Under the constraints of the two major factors of clear height and load bearing, traditional treatment methods such as paving hot asphalt, micro-surfacing, and overlay on bridge decks and tunnel roads obviously cannot meet the requirements of the road itself
