Dezhou Hengda Road Construction Machinery Co., Ltd. is mainly engaged in: colored asphalt, colored asphalt equipment, asphalt tank, emulsified asphalt equipment, modified asphalt equipment hot-mix colored asphalt concrete transportation precautions: 1. It is advisable to use large-tonnage trucks, and pay attention to insulation, the temperature drop to the construction site does not exceed 10℃. 2. The vehicle should be scrubbed in advance to avoid contamination of the raw material black asphalt mixture. Emulsified asphalt isolation oil cannot be sprayed, but edible oils such as vegetable oil, soybean oil, etc., or emulsified asphalt or diluted asphalt prepared from colored asphalt binders should be used. The color asphalt produced by Texas Hengda Road Construction Machinery, quality*, your satisfaction is Hengda's pursuit! Colored asphalt pavement mainly refers to asphalt concrete pavement with added pigments. It uses petroleum resin (light asphalt) and asphalt pavement with pigment added in the mixture. Colored asphalt uses light (or colorless) cementing material, which is currently the most used variety. It uses modern petrochemical products, such as aromatic oils, polymers, resins, etc., to blend bonding materials with comparable properties to ordinary asphalt, and then add some kind of pigment, Make it take on a certain color. Depending on the needs, different types of colors can be added to achieve the required aesthetics and functionality. Black asphalt mainly uses road petroleum asphalt, which is a product of the raw oil processing process. At room temperature, it is a black or dark brown viscous liquid, semi-solid or solid. Since the asphalt contained in asphalt is a black amorphous substance, its content is 2%-15%, so it is revealed that the black colored asphalt mixture is paved with a paver. The screed width and slope sensor should be adjusted first; the screed is heated to about 130℃, and the paver speed is controlled between 2m/min to 6m/min to ensure construction continuity as much as possible; corner defects should be repaired manually. In addition to meeting the requirements of ordinary asphalt pavement construction technical specifications, colored asphalt pavement paving should also meet the following requirements: 1. Clean the paver before paving to prevent the pollution of the original black asphalt; 2, the underbearing surface of the color pavement should be clean and flat, and before paving the colored asphalt mixture should be sprinkled with diluted oil prepared with light cementing material as the adhesive layer oil; 3. If there is serious contamination, separation, Mixtures with large color differences should be removed;
