Cold mixed color asphalt Advantages:

1.Variety of colors

Hot mixed colored asphalt concrete has high requirements for high temperature resistance of pigments, generally above 300℃. This threshold restricts the diversity of hot mixed process color, so that most of the colored asphalt is red, making the word "color" not worthy of the name.

The birth of cold mix technology broke this restriction, customers can choose colors freely according to their preferences, and the cost of red, orange, yellow, green, blue and other colors is basically close.

The same type of pigment is used in the cold mixing and hot mixing processes, but because the cold mixed color asphalt does not need to be mixed at 200℃ for 1 minute, the color of the cold mix is more gorgeous. Even if the iron oxide red pigment with high temperature resistance of 300℃ will have certain impurities denaturation in the high temperature process, resulting in color difference, and the cold mixing process has not been tested at high temperature, the molecular composition of the pigment has not changed, and the structure is more stable, so that the color is more bright and maintained for a longer time.

2. Effectively prevent peeling

To extend the service life of the road, the asphalt material with special formula is used to ensure that the bonding material itself has better bonding performance. Asphalt mixture has pressure-sensitive performance, the greater the traffic volume, the stronger the adhesion between the thin cover and the original road surface.

3. Reduce road maintenance costs

The cost of asphalt materials is reduced by 50%. The thickness of conventional hot mixed colored asphalt concrete surface construction is generally not less than 3 cm, while the thickness of cold mixed colored asphalt is generally 0.7-1.5cm, and the typical thickness is 1.2cm, so it can save 50% of the cost.

4. Reduce water mist on the road and improve driving safety

The principle of cold mixed colored asphalt to reduce water mist: cold mixed colored asphalt is a unique OGFC-5 open gradation skeleton void structure, the pavement void rate is as high as 12%, so it has a higher water permeability coefficient than the ordinary dense gradation asphalt pavement. 

Therefore, in the "cold mixed colored asphalt" road surface, the rain can be discharged to the side of the road meter along the road connectivity gap, which is difficult to form road surface water, thereby reducing the driving water mist and improving the safety of vehicle driving in rainy days.

5. Slip resistance

The cold mixed colored asphalt system has good anti-sliding ability to ensure the anti-sliding ability of the road surface, improve the adhesion of the tire in rainy days, and reduce the road traffic accidents, especially the traffic accidents in rain and snow.

6. Reduce pollution and protect the environment

The construction of "cold mixed colored asphalt" is carried out at normal temperature, and there is no smoke and dust discharge when the hot mixed material is used, which will not cause harm to the environment and meet the requirements of environmental protection.
