Problems solved by technology

[0006] In order to solve the above-mentioned problems, the present invention provides a kind of anti-slip colored pavement surface layer and paving method thereof, and the present invention can preferably solve the poor anti-slip performance, high noise and serious glare of ordinary cement concrete pavement (non-colored cement The road surface is off-white, the light shines on it, directly reflects, causing glare), and also solves the above-mentioned problem of poor skid resistance of the colored asphalt pavement surface layer, which is not conducive to traffic safety, easy to deform at high temperature, low strength, poor wear resistance, and poor craftsmanship. Complicated, high cost and other shortcomings, can be widely used in high-speed heavy-duty traffic

Embodiment 1

[0071] Firstly, the cement concrete with crushed stone gradation 5-10mm:10-20mm=1:6 is paved, vibrated and plastered on the base 3 of the pavement. When the surface temperature of cement concrete is 15°C, wait for After the water film on the surface of cement concrete disappears, apply 200g / m 2 After spraying the retarder at a certain dosage, immediately cover it with a plastic film for the first curing. Be careful not to have air bubbles. When the ambient temperature is 10°C, the curing time is 30 hours. Remove the plastic film and brush off the uncondensed mortar on the surface of the cement concrete, so that the surface of the cement concrete exposes evenly distributed crushed stones with a depth of 2.5 mm (measured by sand-laying method), and the degree of exposed stones is 40 pieces / m 2 , then carry out the second health care, then remove the dust and debris on the surface, apply a mixture of water-based epoxy resin binder and monochromatic color pigment (iron oxide red, ...

Embodiment 2

[0074] First of all, the cement concrete with crushed stone gradation 5-10mm:10-20mm=1:4 is paved, vibrated and plastered on the base of the pavement. When the surface temperature of the cement concrete is 30°C, the cement concrete table

[0075] After the surface water film disappears, apply 250g / m on its surface 2 After spraying the retarder at a certain dose, immediately cover it with a plastic film for the first curing. Be careful not to have air bubbles. When the ambient temperature is 20°C, the curing time is 20 hours. When the main cement concrete of the curing reaches a strength of 3.5MPa, Then uncover the plastic film, brush off the uncondensed mortar on the surface of the cement concrete, so that the surface of the cement concrete exposes evenly distributed crushed stones with a depth of 2.5 mm (measured by sand-laying method), and the exposed stone degree is 45 / m 2 , then carry out the second health care, then remove the dust and debris on the surface, apply a m...

Embodiment 3

[0078] First of all, cement concrete with crushed stone gradation 5-10mm:10-20mm=1:3 is paved, vibrated and plastered on the base course of the pavement. When the surface temperature of cement concrete is 45°C, the surface After the water film disappears, apply 300g / m on its surface 2 After spraying the retarder at a certain dose, immediately cover it with a plastic film for the first curing. Be careful not to have air bubbles. When the ambient temperature is 30°C, the curing time is 15 hours. When the main cement concrete of the curing reaches a strength of 2.5MPa , and then uncover the plastic film, brush off the uncondensed mortar on the surface of the cement concrete, so that the surface of the cement concrete exposes evenly distributed gravel with a depth of 2 mm (measured by sand-laying method), and the degree of exposed stone is 50 pieces / m 2 , then carry out the second health care, then remove the dust and debris on the surface, apply a mixture of water-based epoxy res...

Abstract

The invention discloses a sliding-resistant colored pavement surface and a paving method thereof. The paving method comprises the following steps that (1) cement concrete is subjected to blending, paving, vibrating, excess water removing and plastering, and then paved on a base layer of a pavement; (2) after a surface water film disappears and the surface temperature of the cement concrete is 15-45 DEG C, a retarder is sprayed to the surface of the cement concrete; (3) a plastic film is paved on the cement concrete immediately for primary curing; (4) the plastic film on the surface of the cement concrete is uncovered after the primary curing time is due, and uncondensed cement mortar on the surface of the cement concrete is brushed away; (5) secondary curing is conducted till the cement concrete reaches a certain strength; (6) after the cement concrete reaches the certain strength, dust and chips on the surface of the cement concrete are removed, and colored pigment is smeared; and (7) tertiary curing is conducted, and the whole paving process is completed after the cement strength reaches the final strength. According to the sliding-resistant colored pavement surface and the paving method thereof, the construction depth and friction coefficient of the cement concrete pavement surface are additionally considered, and meanwhile, the pavement is colored.

Description

technical field [0001] The invention belongs to the field of pavement engineering, and in particular relates to an anti-skid colored pavement surface layer and a paving method thereof. Background technique [0002] In recent years, with the rapid development of economy and technology, people have higher and higher requirements for the coordination between road environment and urban environment, and higher requirements for road comfort and functionality. Roads are required not only to provide safe and reliable passages, but also to be able to coordinate with the surrounding environment, reduce the environmental load, and provide more comfort to users at the same time. The driving noise of ordinary cement concrete pavement is much louder than that of asphalt pavement. In view of this, Austria invented a "low noise" concrete pavement in 1992. The main feature is to expose the concrete pavement aggregates to reduce noise. Britain, Germany, France, Japan, Belgium, Denmark and o...
