Generally speaking, the cost of laying asphalt concrete is higher than that of ordinary cement concrete. If the money is enough, people still prefer to pave roads with asphalt concrete. Compared with pure concrete roads, the performance of roads will be significantly improved after the addition of asphalt. When you drive, you should find that the car is driving on asphalt roads, the noise is smaller, the damage to the tires is less, and the vehicle has less bumps. Asphalt roads are more wear-resistant, easy to clean, and have a certain adsorption effect on dust, and are not easy to generate dust.


The most important thing is that its thermal expansion and contraction effect is not obvious. If there is no road seam reserved for cement roads, the road will bulge in summer, and there is even a risk of explosion. Of course, asphalt concrete also has disadvantages. Its road surface hardness is worse than that of cement roads, and its life is generally shorter than that of cement roads.
