The colors used in colored asphalt usually consist of the family of organic and organic-mineral pigments and can be used from matte colors to bright and reflective colors in liquid or powder form.
In ancient civilizations, various natural materials were used to create colored pavements, including crushed precious stones and shells. However, it was not until the 1960s that modern techniques were developed to produce pigmented asphalt mixtures using artificial pigments.
Colored asphalt mix is usually prepared by asphalt companies or production units. Its production process includes the following steps:
In the production of colorful asphalt mixture, raw materials with specific standards for asphalt are used. These raw materials include aggregate granules, binders (such as petroleum bitumen) and gilsonite or natural bitumen or other fillers. Also, to produce this product, suitable colored materials in the form of powder or liquid are used to create the desired color.
mixingThe raw materials are identified in the order that they include natural bitumen or natural gilsonite or petroleum bitumen and powder paint or liquid paint and sand or gravel and are mixed in specific proportions. Mixing may be done manually or using asphalt mixing machines (eg, ready-mixed asphalt). in this
process, the raw materials are mixed and combined to obtain a uniform mixture suitable for use in pigmented asphalt.
After mixing the raw materials, coloring materials are added to the mixture. These colorants are usually available in powder or liquid form and are added to the mixture depending on the need and desired color. Note that colored materials must be combined with other materials to create the desired and uniform color for pigmented asphalt.
After adding colored materials, the final mixture consists of a mixture of Gilsonite or natural bitumen and refinery bitumen with sand and gravel and color, which must be completely mixed and uniform. This step may be done using asphalt mixing machines or other equipment. The purpose of final mixing is to achieve a uniform and standardized mixture that can be applied well on the road surface.
After production, the mixture should be transported to the work sites and kept in proper conditions. This includes maintaining the proper temperature to maintain the temperature and quality of the mixture, storing in proper containers, and maintaining proper ventilation. Also, the asphalt mixture must be applied at the right time and under the right conditions on the road surface so that it stabilizes well and creates the desired color.
One of the main advantages of this type of asphalt is its ability to increase the visual appeal of roads, corridors and other paved surfaces. With a wide range of colors available, it offers endless possibilities for creative design and customization.
