Embodiment 1

[0033] A kind of pavement antiskid surface repair material comprises following components: 100 kilograms of water-soluble polyurethane emulsions; 20 kilograms of carbon blacks, 10 kilograms of alkaline mineral powders, 152 kilograms of carborundum powders. Among them, the water-soluble polyurethane emulsion is stirred and mixed with carbon black and alkaline mineral powder to form a cementing material, and emery is a wear-resistant aggregate.

[0034] The method of pavement anti-skid repair using the repair material made above is as follows:

[0035] (1) Milling on the original old asphalt pavement, so that the original road surface has a certain rough surface. Clean and dry after milling to ensure the road surface is clean.

[0036] (2) Anti-skid repair material spraying. Use a sprayer to spray the cementitious material and wear-resistant aggregate simultaneously on the road surface to be repaired at one time. Among them, by weight, the spraying amount of cement is 0.3kg / m...

Embodiment 2

[0039] A pavement antiskid surface repair material comprises the following components: 100 kilograms of water-soluble polyurethane emulsion; 25 kilograms of toner, and 140 kilograms of basalt sand powder. Among them, the water-soluble polyurethane emulsion and the toner are stirred and mixed to form a cementing material, and the basalt sand powder is a wear-resistant aggregate.

[0040] The method of pavement anti-skid repair using the repair material made above is as follows:

[0041] (1) Milling on the original old asphalt pavement, so that the original road surface has a certain rough surface. Clean and dry after milling to ensure the road surface is clean.

[0042] (2) Anti-skid repair material spraying. Use a sprayer to spray the cementitious material and wear-resistant aggregate simultaneously on the road surface to be repaired at one time. Among them, by weight, the spraying amount of cement is 0.4kg / m 2 , the spraying amount of wear-resistant aggregate is 0.4kg / m ...

Embodiment 3

[0045] A pavement antiskid surface repair material comprises the following components: 70 kilograms of water-soluble polyurethane emulsion; 25 kilograms of toner, 5 kilograms of carbon black, 60 kilograms of basalt sand powder, and 30 kilograms of quartz sand powder. Among them, water-soluble polyurethane emulsion is stirred and mixed with toner and carbon black to form cementing material, and basalt sand and quartz sand powder are wear-resistant aggregates.

[0046] The method of pavement anti-skid repair using the repair material made above is as follows:

[0047] (1) Milling on the original old asphalt pavement, so that the original road surface has a certain rough structure. Clean and dry after milling to ensure the road surface is clean.

[0048] (2) Anti-skid repair material spraying. Use a sprayer to spray the cementitious material and wear-resistant aggregate simultaneously on the road surface to be repaired at one time. Among them, by weight, the spraying amount of...

Abstract

A millimeter-level pavement antiskid surface rapid repair material and a pavement antiskid rapid repair method are provided; the material is made from, by weight, 6-10 parts of a cementing material and 7-9 parts of wear-resistant aggregate, wherein the cementing material contains 70-85% by weight of waterborne polyurethane emulsion. The repair material has high adhesion with an original pavement under repair, and has the properties such as waterproofness, ultraviolet resistance, and the ability to inhibit aging and bulking of the original pavement; by transferring the cementing material and wear-resistant aggregate in the above material synchronously to a pavement under repair, a millimeter-level ultrathin antiskid surface layer is formed; the method is simple to perform, can provide a shortened construction period, has good repair effect for a pavement, and enables traffic to be normalized within a short time.

Description

technical field [0001] The invention relates to the field of roads, in particular to a millimeter-scale pavement anti-skid surface rapid repair material and a pavement anti-skid rapid repair method. Background technique [0002] During the course of use, the pavement of roads of various grades and municipal roads is subjected to factors such as vehicle load and climate environment for a long time, and the anti-skid performance of the road surface declines year by year. Some poor-quality roads, when there are no other serious diseases on the road surface, the anti-skid performance of the road surface can no longer meet the use requirements within 3-4 years, causing a major safety risk to people's lives and property. [0003] In this case, in order to better ensure the function of the road surface and effectively ensure driving safety, the highway management department or operator will carry out maintenance and repair in time to restore the anti-skid function of the road surfa...
