Simply put, asphalt is characterized by good elasticity and good overall paving consistency, but its disadvantage is soft deformation at high temperature, which is not obvious on expressway pavement. Asphalt pavement is widely used in road construction in places such as toll stations where deceleration, parking and acceleration are needed. At present, most of expressway adopts asphalt pavement. Asphalt combined with mineral materials paves the road, making the road smooth, less dust, impervious and durable. 1, the smoothness of asphalt pavement is higher than that of cement pavement. 2. Asphalt pavement has certain flexibility and can be in close contact with tire rubber. 1, the smoothness of asphalt pavement is higher than that of cement pavement. 2.

It can be said that cement concrete pavement and asphalt pavement have their own advantages and disadvantages. Advantages of cement pavement: Because cement concrete is a rigid material, it has high strength, good deformation resistance, good wear resistance, good night reflection performance and strong temperature change resistance. Disadvantages of cement pavement: Because of the existence of expansion joints, the driving comfort is poor, and it takes a maintenance period to repair after damage.

Asphalt mixture is a viscoelastic plastic material. It not only has good mechanical properties, but also has certain high-temperature stability and low-temperature flexibility. The pavement paved with it is smooth and seamless. Permeable asphalt pavement is also called "drainage and noise reduction pavement". It is a new type of pavement structure, and the raw materials are mixed with specially developed modified asphalt, hydrated lime and fiber, which can effectively reduce the blasting sound caused by the friction between high-speed vehicles and the pavement.

Asphalt concrete pavement is the most common pavement now, because its color is black, so it is called black pavement and cement pavement is called white pavement. The construction speed of asphalt concrete pavement is fast, and the tire noise generated by cement concrete pavement is much higher than that of asphalt pavement because the smoothness of cement pavement is lower than that of asphalt pavement, while cement concrete is a rigid material and asphalt is a flexible material.

Asphalt pavement is a pavement structure with a certain thickness of asphalt mixture laid on flexible base and semi-rigid base. Compared with gravel pavement, the strength and stability of this kind of pavement are greatly improved. Compared with cement concrete pavement, 1 and asphalt pavement have higher flatness than cement pavement. 2. Asphalt pavement has certain flexibility and can be in close contact with tire rubber.
