Now we will see that most of the construction of highway pavement is mostly used by asphalt material, naturally because of the advantages of asphalt material itself, let's see.
Comfortableasphalt is characterized by soft, elastic and easy leveling, while cement is harder and has poor leveling performance. Considering the problem of thermal expansion and contraction, each section of cement road should leave a little space. From the point of view of the car, the noise of cement road will be much bigger, and this advantage is not obvious at low speed, but the highway is often more than 100 yards per hour, of course, on the asphalt road is more comfortable to drive, so a little grade of the highway, generally with asphalt pavement.
SafetyJi 'nan asphalt manufacturers think that the laying of highway, the important thing is not cost, not life, but safety. The most important point that directly affects the safety of driving is the friction between tires and the ground, which has a great relationship with the material of the road surface. And the asphalt material is thicker, the contact surface is ideal, the friction force is strong, the adhesion is good, and the cement is smooth. While some artificial gullies can be used to increase friction, the overall situation is not ideal, making braking at high speeds more problematic and rain more dangerous than asphalt.
Convenientconcrete takes a long time to set, which requires formwork for installation and tamping, and often requires sealed roads for maintenance and water spraying. If cracks and other problems occur, excavation operations are often required. Asphalt is ideal for plasticity and is easier to process into thin layers, and resurfacing is usually sufficient. Asphalt pavement does have advantages for highways that pay attention to aging. In addition, many large trucks in China are overloaded and the road surface is often crushed. Using asphalt inside can be a quick fix.
In addition, asphalt as the material of highway pavement construction in the later maintenance is also more convenient, only two or three people, will boil the good asphalt into the damaged place, and then use a small roller to compact the road.
