We usually shout the slogan "Build roads first if you want to get rich", and the development and progress of society is indeed indispensable for the construction of roads. Why choose asphalt pavement with higher price and lower hardness than cement pavement for highway construction?
Most of the cars driving on the highway are transported across provinces and most of them are trucks, so the long-term mass transportation will have a certain impact on the pressure on the wheels and the road surface. Asphalt pavement is soft and has some pores, which not only absorbs noise and dust, but also overcomdurabilityes the serious friction on the wheels. Therefore, the selection of asphalt pavement for expressway is a more suitable application.
However, some people doubt the instability brought by asphalt pavement. Asphalt pavement is easy to crack during long-term construction and use, and its durability is not very high. The construction of the road itself needs to consider various factors in terms of materials. Compared with the cement pavement, all aspects of the asphalt pavement are more suitable for the laying of highways.
The laying speed of asphalt pavement is fast and the time is short. After a certain period of natural cooling, normal driving can be achieved. Moreover, the traffic flow on the expressway is large. When encountering a road repair situation, it happens that the repair of the asphalt pavement only needs to repair the damaged position, and the solidification time of the asphalt is very fast, and it can be opened to traffic after 3-4 hours of complete cold cutting.
