Asphalt refers to the use of asphalt in roads, roofs and other construction projects. It is a black gelatinous substance, mainly obtained by refining fossil fuels such as oil and natural gas, and has excellent adhesion, water resistance and weather resistance. Asphalt is widely used, in addition to being used in construction projects, it can also be used for asphalt pavement, waterproof materials and anti-corrosion materials. This paper will discuss the role and application of asphalt from many aspects.

1. Asphalt in the role of construction projects

1. Road construction

Asphalt pavement is currently widely used in road construction, it has excellent weather resistance and freeze-thaw resistance, to meet the needs of high-speed vehicles smooth road surface. In addition, asphalt pavement can also reduce vehicle noise, reduce road damage and improve driving safety performance.

2. Roof construction

asphalt is also widely used in roof construction, it can be used as a flexible waterproof material. The roof surface paved with asphalt is smooth and flat, and the thickness can be adjusted according to needs. In addition, the asphalt roof can effectively sound insulation, waterproof, protect the building from damage in bad weather conditions.

3. wall construction

asphalt material can effectively protect the wall from water immersion, as well as fire prevention and corrosion protection. In the construction of the wall, the use of asphalt can enhance the firmness of the wall and increase the isolation effect of the wall on the external noise.

4. Bridge construction

asphalt is widely used in bridge construction, mainly to prevent the surface of the bridge from rusting and to enhance the bearing capacity of the bridge deck layer. The paving of asphalt on the bridge deck layer can protect the steel structure from rust caused by external influences, thereby increasing the service life and safety of the bridge.

2. in other areas of asphalt application

1. waterproof material

asphalt can be used for building roof, doors and windows and basement and other areas of waterproof treatment. Asphalt has good adhesion and can effectively prevent water penetration.

2. anti-corrosion material

asphalt has good acid and alkali resistance and corrosion resistance, so it can be used for anti-corrosion treatment, in buildings, oil tanks, ships and other fields have been widely used.

3. Asphalt Concrete

Mixing asphalt and concrete can improve the strength and wear resistance of concrete. In addition to being used as a pavement material, asphalt concrete can also be used in engineering fields such as dams, underground tunnels and airport runways.
