What Are the Advantages of Emulsified Bitumen Compared to Hot Asphalt and Diluted Asphalt?

With the vigorous development of China's road construction, people gradually realize that the excellent pavement performance of emulsified asphalt is a maintenance method and maintenance material that can play a good role in improving China's pavement problems. Through years of practice, it has been proved that emulsified asphalt has many advantages over hot asphalt and diluted asphalt:

(1) Low maintenance cost. The use of emulsified asphalt can greatly reduce the cost of construction and maintenance of roads, so that limited funds can play a greater role.

(2) Improve road quality. When using hot asphalt, the sprayed hot asphalt will quickly solidify and no longer have fluidity, so it is difficult to ensure the uniformity of asphalt spraying. The emulsified asphalt is liquid at room temperature and has good fluidity. The content of asphalt can be adjusted according to the specific conditions during construction to meet the needs of the project and improve the quality of the road surface.

(3) Expand the use of asphalt. Emulsified asphalt can be used for both building and repairing roads.

(4) Save energy and resources. When using hot asphalt to lay the road surface, during the transportation and use of asphalt, the asphalt needs to be continuously heated or insulated, which is easy to cause asphalt aging and waste a lot of energy. The emulsified asphalt is only heated when the asphalt is emulsified, which saves a lot of energy.

(5) Extend the construction season. Using emulsified asphalt to construct the pavement can effectively reduce the impact of cold, humid and low temperature climate on the project. The road surface can be repaired and laid even before and after the rainy season.

(6) Protect the environment, reduce pollution, and improve working conditions. Using ordinary asphalt to lay the road surface, the asphalt needs to be heated to a very high temperature and the heating time is very long. The steam released when the asphalt is heated contains harmful substances, which not only pollutes the environment, but also causes great harm to the health of the workers. In the production process of emulsified asphalt, the asphalt does not need to be heated to a very high temperature, which directly reduces the heating time, and the degree of pollution is also reduced. Moreover, when emulsified asphalt is used to lay the road surface, it is carried out at normal temperature, which greatly improves the staff. The working conditions reduce pollution and can effectively ensure the health of construction workers.
