Skidproof permeable road pad and manufacturing technology thereof

Abstract

The invention relates to a skidproof permeable road pad and a manufacturing technology thereof. The skidproof permeable road pad has good water permeability, good air permeability, antiskid performances, wear resistance, weatherability, sound-absorbing functions, a low production cost, and a low maintenance cost. The skidproof permeable road pad provides an approach for waste and old rubber recycle, and reduces environmental protection pressure caused by waste and old rubber rapid increasing caused by rapid development of economy. The skidproof permeable road pad is characterized in that the skidproof permeable road pad comprises a bottom layer having the thickness of 1 to 5 centimeters and a surface layer which is sprayed on the surface of the bottom layer and has the thickness of 1 to 3 millimeters, wherein the bottom layer is prepared from rubber particles having sizes of 2 to 5 millimeters and single-component polyurethane glue water by uniform stirring and cementation, and a weight ratio of the rubber particles to the single-component polyurethane glue water is (6 to 7): 1. The skidproof permeable road pad is suitable for various pavements used for municipal transportation, especially, is suitable for underground channels, platform bridges, bus stations, bicycle tracks and sidewalks in an urban area, and can improve urban living driving safety and pedestrian safety.

Description

technical field [0001] The invention relates to a non-slip and water-permeable road mat and its production process, which is mainly applicable to various road surfaces of municipal traffic, especially underground passages, overpasses, bus stops, bicycle lanes, sidewalks, etc. Safety. Background technique [0002] At present, most of the municipal roads in China are paved with concrete and asphalt, and most of the overpasses, underground passages, underground parking lots, etc. in the urban area are also paved with cement pavements or floor tiles. These road surfaces have some common problems in the process of use. The anti-skid performance is unstable. In rainy and snowy days, the road surface is easy to accumulate water and freeze, which makes it difficult for pedestrians to drive and cause traffic accidents. The asphalt road surface is afraid of heat and easy to soften in summer. , In winter, it is afraid of cold and easy to crack, afraid of rain soaking and washing, sand...

AI Technical Summary

Problems solved by technology

These road surfaces have some common problems in the process of use. The anti-skid performance is unstable. In rainy and snowy days, the road surface is easy to accumulate water and freeze, which makes it difficult for pedestrians to drive and cause traffic accidents. The asphalt road surface is afraid of heat and easy to soften in summer. , In winter, it is afraid of cold and easy to crack, afraid of rain soaking and scouring, sand and gravel are easy to peel off, etc.

The asphalt pavement of urban bus stops, in high temperature weather in summer, will bulge or form uneven low-lying areas due to the high-frequency heavy-duty driving thrust pushing the pavement, which needs to be repaired several times a year; overpasses are prone to snow and water accumulation in rainy and snowy weather Ice, which makes it difficult to walk on the road, and the corresponding underground passages also have potential safety hazards such as summer return, water accumulation on rainy days, and poor anti-skid performance; and when pedestrians walk on some loose floor tiles on the sidewalk, they often splash out from the gaps. Sewage, dirty pedestrian pants, shoes and the ground, need frequent maintenance
