Asphalt is a black viscous substance extracted from the processing of petroleum, also known as bitumen. It is a complex mixture containing a variety of compounds, the main components of which are hydrocarbons such as benzene, toluene, xylene, etc. The main use of asphalt is as a building material and pavement material.
In construction, asphalt is mainly used to make waterproofing materials and roofing materials. Its viscosity and waterproof properties make it an excellent waterproof material, which is commonly used in basements, underground garages, roofs and other building parts for waterproofing treatment. In addition, asphalt can also be made into anti-corrosion materials for anti-corrosion treatment of wood, metal and other items.
In road construction, asphalt is mainly used to make pavement materials. Asphalt pavement can be divided into asphalt mixture pavement and asphalt pavement. Asphalt mixture pavement is to mix asphalt and stone in a certain proportion and then lay on the pavement, its advantages are good slip resistance, high durability, simple construction process. Asphalt pavement is to heat asphalt and coat it on the pavement, and its advantages are fast construction speed and low cost. The application of asphalt can greatly improve the driving comfort and durability of the road, and improve driving safety.
In addition to this, asphalt has some other uses. For example, asphalt can be used to make tar dyes, dye, etc. Asphalt dyes are widely used in printing and dyeing, ink, shoe making and other industries. In addition, asphalt can also be used in the production of sunscreen, skin care products and other cosmetics, which has a certain effect of protecting the skin.
In general, asphalt is an important industrial raw material with a wide range of applications. With the continuous development of technology, the use of asphalt is also expanding and innovating.
