Single particle size ultra-thin anti-slip wearing layer used for road preventive maintenance and construction process thereof

Abstract

The invention discloses a single particle size ultra-thin anti-slip wearing layer used for road preventive maintenance and a construction process. The single particle size ultra-thin anti-slip wearinglayer is formed by paving and rolling a single particle size asphalt mixed material on a road surface by a paver, and the asphalt mixed material includes modified emulsified asphalt and basalt aggregate. Compared with existing anti-slip performance improvement measures, the wearing layer can greatly improve the anti-sliding performance of the road surface without significantly increasing elevation of an original road surface, and has the advantages of good water resistance, seam sealing, slip resistance, noise reduction, and the like, and the modified emulsified asphalt can restore aged asphalt of an original asphalt road surface to some extent. The paving thickness of the ultra-thin anti-slip wearing layer can be low to 5 mm, so that the cost is relatively low, and the wearing layer hasan outstanding economic advantage compared with the prior art. The original asphalt road surface is directly paved with the single particle size ultra-thin anti-slip wearing layer, the influence of water and atmospheric effects on the original asphalt road surface can be alleviated, and the service life of roads is prolonged.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a single particle size ultra-thin anti-skid wear layer for road preventive maintenance and a construction process thereof. Background technique [0002] At present, my country's road construction is booming, and the mileage of traffic continues to extend. With the increasing role of roads in people's production and life, road surface functional damage and deficiencies other than road structural diseases have also attracted more and more attention. . Insufficient functionality of the road surface means that the road surface is difficult to provide the conditions for normal driving of the vehicle, such as anti-skid performance, flatness, etc. As a preventive maintenance technology, the ultra-thin anti-skid wear layer with a single particle size is only 5mm thick, so it can improve the anti-skid performance of the road surface and improve the safety of vehicles without sign...

Problems solved by technology

[0003] At present, the maintenance measures used to improve the anti-skid performance of the pavement mainly include: synchronous gravel seal, micro-surface, chip seal and sand-mist seal, etc., and if the micro-surface is laid on the road surface, it will This leads to a sharp increase in vehicle driving noise, which seriously affects the quality of drivers and passengers, reduces the comfort of drivers and passengers, and affects the daily life of residents on both sides of the road; in addition, the thickness of the existing wear layer is mostly 1.5- 3cm, the construction cost is relatively high, and it is only used to improve the anti-skid performance of the road surface, and the economy is relatively poor; moreover, during the construction process, the mixture is mostly hot-mixed, which increases the emission of harmful gases to a certain extent, which is not conducive to my country's new construction.
