Problems solved by technology

However, this method of mixing and mixing at a specific temperature is increasingly unable to adapt to the progress of society. People's visual aesthetics and requirements are constantly improving. Roads driven by motor vehicles, or used in different areas such as schools, stadiums, recreation, etc., will be replaced by cold-mixed and cold-paved methods in terms of color diversity and construction flexibility.

specific Embodiment 1

[0029] A construction technique for colored asphalt pavement, the object of use is motor vehicles, the base surface is new black asphalt concrete, and the area is about 3000 square meters. It mainly includes the following steps:

[0030] Step 1: On the first day, close the traffic and clean the road surface; check the working status of generators, air compressors, small hand-push mixing barrels, small hand-push ultra-fine sprayers, etc.;

[0031] Step 2: Lay out the wires and stick out the edge line with 10-15cm paper tape, determine the construction area, and prepare 2-3 spraying baffles (baffle size: height 1.2m*length 2m) to prevent splashing during spraying and pollute the environment ;

[0032] Step 3: According to the amount of colored asphalt emulsion and mixture per unit area, stack the corresponding raw materials equidistantly, weigh a certain amount of colored asphalt emulsion according to the construction ratio and add it to the small hand-push mixing tank, and the...

specific Embodiment 2

[0037] An ultra-micro-spraying construction process for colored asphalt pavement, the object of use is motor vehicles, the base surface is cement concrete that has just been cured, about 2000 square meters, mainly including the following steps:

[0038]Step 1: On the first day, close the traffic and clean the road surface; check the working status of generators, air compressors, napping machines, small hand-push mixing barrels, small hand-push ultra-fine sprayers, etc.;

[0039] Step 2: Lay out the wires and stick out the edge line with 10-15cm paper tape, determine the construction area, and prepare 2-3 spraying baffles (baffle size: height 1.2m*length 2m) to prevent splashing during spraying and pollute the environment ;

[0040] Step 3: Rafting of the base surface: Since the original road surface is a cement concrete layer, the surface is flat and smooth, and there is almost no structural depth, the cement concrete layer needs to be roughened first (the roughening depth is ...

specific Embodiment 3

[0047] An ultra-micro-spraying construction technology for colored asphalt pavement, the object of use is non-motor vehicles, the base surface is black asphalt concrete, the color is red and green, and the red area is 1500 square meters, and the green area is 400 square meters. It mainly includes the following steps:

[0048] Step 1: On the first day, close the traffic and clean the road surface; check the working status of generators, air compressors, small hand-push mixing tanks, small hand-push ultra-fine sprayers and other equipment;

[0049] Step 2: Lay out the wires and stick out the edge line with 10-15cm paper tape, determine the construction area, and prepare 2-3 spraying baffles (baffle size: height 1.2m*length 2m) to prevent splashing during spraying and pollute the environment ;

[0050] Step 3: On the first day, first complete the coarse-grained spraying of 1500 square meters of red single-layer structure. According to the amount of colored asphalt emulsion and ...

Abstract

The invention discloses an ultra-micro spray construction process for a color asphalt pavement. The construction process has an advantage that the construction process can easily and flexibly deal with various situations on a small-area and irregular base surface, especially a colorful square and park, a bicycle lane of a divided region and the like. The construction process is most suitable for exercise and fitness, walking and shared riding, the anti-slip effect is obvious, the construction process cannot cause harm to the surrounding environment, the construction is fast and the efficiency is high, and the traffic delay caused by construction is effectively reduced.

Description

technical field [0001] The invention belongs to the field of colored emulsified and decolorized asphalt, and in particular relates to an ultrafine spraying construction process for colored asphalt pavement. Background technique [0002] Colored asphalt, also known as colored cementitious material, is a kind of road construction material. It is widely used in slow traffic systems such as greenways, bicycle lanes, and garden landscape roads. It can also be used in bus lanes, intersections, and expressway service areas. and other heavy traffic roads. There are currently two kinds of commonly used colored asphalt: the first one is colorless cement with color powder added, and the colorless cement can be obtained by decolorizing asphalt or blended with light-colored polymers such as petroleum resins. Paving hot asphalt is realized in the same construction method; the second method is to prepare emulsified decolorized asphalt by using colorless cement as raw material through a sp...
