Anti-skid colored paving material for roads, and preparation method and construction process of paving material

Abstract

The invention provides an anti-skid colored paving material for roads, and a preparation method and a construction process of the paving materials. The anti-skid colored paving material for roads comprises the following components in parts by weight: 40-50 parts of polymethyl methacrylate resin, 10-20 parts of calcium carbonate, 1-5 parts of nano silicon dioxide, 2-5 parts of inorganic pigment, 5-15 parts of bauxite and 5-8 parts of quartz sand. The anti-skid colored paving material for roads provided by the invention has a shortened hardening time, and the bauxite with excellent acid resistance, alkali resistance and chemical resistance is used as the main material, so that an original working procedure of additional removal of anti-skid aggregates can be omitted, and the problems that the aggregate easily peels off from the paving material and uniform spreading is difficult due to uneven aggregate shape existed in the additional removal of the aggregates can be solved. Pre-mixing iscarried out for coating the aggregate with the quartz sand, the aggregate does not fall off easily, the drying time is faster, the traffic condition can be reached only in one hour, and the traffic pressure is greatly reduced.

Description

technical field [0001] The invention belongs to the field of road paving materials, and in particular relates to a non-slip colored road paving material, a preparation method and a construction process. Background technique [0002] On roads with steep slopes, roads around schools, urban non-motor vehicle lanes, tunnel entrances, park landscape roads and other roads, in order to prevent vehicle skidding due to high humidity or icing, the road surface is coated with various anti-skid pavement materials, Ensure the safety of vehicles and people driving or walking on these roads. [0003] At present, the anti-slip pavement in the prior art generally adopts the construction technology of spreading the anti-slip aggregate after the road surface is coated with resin, and the construction of this anti-slip technology not only has a long construction period, but also the construction procedure is relatively complicated, and the process of throwing ceramic particles is extremely diff...

AI Technical Summary

Problems solved by technology

[0003] At present, the anti-slip pavement in the prior art generally adopts the construction technology of spreading the anti-slip aggregate after the road surface is coated with resin, and the construction of this anti-slip technology not only has a long construction period, but also the construction procedure is relatively complicated, and the process of throwing ceramic particles is extremely difficult. It is easy to drag the grains, and the grains will fall off within a period of time after cutting because the surface layer of the grains is not firmly bonded.

What's more serious is that when the anti-skid pavement materials used in the above-mentioned anti-skid construction burn, toxic gases are produced, which leads to secondary accidents.

For example, when a fire occurs due to a vehicle traffic accident, the toxic gas produced by the burning of pavement pavement materials may cause the driver to suffocate. Other pavement processes take a long time to solidify, and the long closure time will greatly affect traffic flow and increase the total social cost.
