What are the advantages of replacing cement pavement with asphalt pavement?
The advantages of cement pavement lie in high temperature resistance, long life and simple construction, so this technology has been used in my country for a long time. However, in the long-term use process, the cement pavement will inevitably produce cracks and other diseases. In addition, the vehicle load continues to increase, and the bearing capacity of the road needs to be properly enhanced, which requires maintenance and renovation of the road surface.
The asphalt pavement surface layer has the characteristics of low noise, high and low temperature stability, impermeability, wear resistance, high rigidity and strength, and the surface roughness and flatness of the surface layer are ideal. From the construction point of view, asphalt concrete pavement is convenient for construction, fast paving, easy to control the smoothness of the road surface, easy to excavate and repair, which can facilitate the secondary laying of underground pipelines in the future; from the perspective of traffic, the asphalt pavement is comfortable to drive. , Good seismic performance and low driving noise. However, the stability and strength of the asphalt surface layer are greatly affected by the soil foundation and the base layer.
Applying asphalt pavement to the reconstruction of cement pavement, the method of adding asphalt surface layer can make use of the strength of cement pavement, improve the pavement performance, and also has the characteristics of convenient construction and low engineering cost, which can reduce the impact on normal traffic as much as possible. Therefore, this technology is widely used in the reconstruction of old cement pavement.
In the process of converting cement pavement to asphalt pavement, construction personnel should actively deal with any problems that may arise during the construction process, seriously deal with each construction link, and continuously improve the construction level. In addition, managers should strengthen overall planning and management, and pay close attention to construction details, so as to ensure the performance of asphalt pavement.
