Problems solved by technology

The color resin anti-slip pavement has a thickness of 1-10mm, simple construction process, rich color types, relatively stable color fastness, relatively cheap price and significant anti-slip effect. However, the construction method of this pavement is to spread a layer of 0.5-10mm aggregate , it is difficult to form a "grain-to-grain" embedding effect, and it is easy to cause local aggregate accumulation, which makes the adhesion between the aggregate and the resin worse
At the same time, the pavement is not sealed with weather-resistant colored epoxy resin and easy-to-clean anti-oil stain resin, and the UV aging resistance and oil stain resistance need to be further improved

Embodiment 1

[0034] Embodiment 1: as figure 1 As shown, the ETC lane of an old toll station in Jiangsu implements the invention on the original cement concrete road surface, and constructs according to the following steps:

[0035] (1) The ambient temperature is 25°C, and the relative air humidity is 69%. Shot blasting is performed on the surface of the original cement concrete pavement at a walking speed of 13m / min, and the working surface after shot blasting is cleaned. mm.

[0036] (2) Prepare the components of the permeable colored resin sealing layer in proportion in the constant temperature box. According to the calculation in parts by mass, it consists of 68 parts of diisocyanate, 10 parts of polyether polyol, 5 parts of polyamine, 15 parts of reactive diluent, The gray colorant is composed of 2 parts. Use a pneumatic agitator to stir each component for 3 minutes, the speed is 180 R.p.m, and the temperature is controlled at 25°C. Use a high-pressure pneumatic spray gun to spray a p...

Embodiment 2

[0046] Example 2: A weather-resistant colored resin overlay and its preparation method

[0047] The parking lot of a large vehicle in a service area of ​​an expressway in Jiangsu is seriously polluted by oil, which greatly affects the beauty of the service area. After the original asphalt pavement is polluted by oil, vehicles tend to slip when parking, and it is difficult to clean the oil.

[0048] Implement the present invention on former asphalt pavement, construct according to the following steps:

[0049] (1) The ambient temperature is 30°C and the relative air humidity is 70%. Shot blasting is performed on the surface of the original asphalt concrete pavement at a walking speed of 15m / min, and the working surface after shot blasting is cleaned. mm.

[0050] (2) Prepare the components of the permeable colored resin sealing layer in proportion in the constant temperature box. According to the calculation in parts by mass, it consists of 66 parts of diisocyanate, 10 parts o...

Abstract

The invention discloses a weather-resistant colored resin overlay and a preparation method thereof, belongs to the technical field of road surface engineering transformation, is suitable for cement and asphalt concrete road surfaces, and aims to provide a weather-resistant, wear-resistant and easy-to-clean Colored resin anti-slip overlay, the main points of the technical scheme are as follows, from bottom to top: permeable color resin sealing layer, weather-resistant color epoxy resin bonding layer, anti-slip embedded hard aggregate layer, easy-to-clean anti-slip Oil-stained resin sealant; permeable colored resin sealant is prepared by mixing and stirring diisocyanate, polyether polyol, polyamine, active diluent, and colorant. It has low initial viscosity and good fluidity, and can penetrate and heal cement pavement or Micro-cracks in asphalt pavement can restore the strength of the pavement structure, and at the same time prevent the damage of the overlay caused by the evaporation of water inside the pavement, and play a sealing role. It has good wear resistance and has industrial value.

Description

technical field [0001] The invention relates to the technical field of road surface engineering transformation, in particular to a colored resin anti-skid overlay with good weather resistance, good wear resistance and easy cleaning and a preparation method thereof. Background technique [0002] In recent years, the application of colored pavement in the road industry has become very common. The colored pavement can beautify the road surface and improve the use of the road surface. In addition, the colored pavement can serve as a warning to vehicle drivers and guide traffic. The traditional colored pavement has certain disadvantages. The asphalt-based colored pavement needs to be paved with asphalt mixture on the original pavement, which has poor connection with the elevation of the unpaved section, and is prone to rutting and moving diseases; the cement-based colored pavement The anti-slip and wear-resistant properties are poor, and the color is easy to fall off, and the dur...
