What are the advantages of asphalt pavement: (1) Compared with ordinary asphalt, colored asphalt is more conducive to reducing dust pollution and noise. Black asphalt usually used for paving roads contains a large number of volatile light fractions, which leads to great environmental pollution, and some even produce "heat island" effect. However, the light fraction of color modified asphalt volatilizes little, so the pollution is much less than that of black asphalt. (2) It is safe and labor-saving to disperse the traffic flow with colors and induce the traffic flow. Different colors of asphalt pavement can improve the driver's recognition effect and make the driver's attention more concentrated, thus playing the role of inducing traffic flow, safe driving and intuitive traffic management.

(3) The pavement has high friction coefficient, is not easy to be damaged, and has good road performance. The new asphalt pavement has higher friction coefficient than ordinary asphalt pavement, so it has anti-skid effect; Under different temperatures and external environment, it has good high-temperature stability, water damage resistance and durability, no deformation, asphalt film peeling and other phenomena, and good adhesion to the base.

(4) beautify the environment. Colored asphalt not only has the good properties of ordinary asphalt concrete, such as strong elasticity, strong shock absorption, easy cleaning and flushing, but also improves the monotony of ordinary asphalt pavement black, which can be matched and coordinated with surrounding buildings and landscapes. Paving pedestrian streets, landscape roads, squares, courtyards, residential roads and gardens with asphalt not only beautifies the environment, but also highlights the natural interest. Colored asphalt pavement has many advantages, safety and durability, and beautifies urban construction. Our company supplies high-quality products and contributes to urban construction!

I use simple knowledge to answer:

1: Asphalt road is also called asphalt road. Its base structure is consistent with cement road (also called reinforced concrete road), but the difference from asphalt road is that a layer of fine stone mixed asphalt is added to the surface.

2. Advantages of asphalt pavement compared with concrete pavement .. The surface layer is soft, so the car will feel comfortable and have some elasticity when walking on it. But concrete is so hard that cars will feel hard when they walk on it. Some small defects in the road surface will give people a strong sense of vibration. B: the scenery. Asphalt pavement is generally black, giving people a deep and steady feeling, which will make people feel more solid when driving. However, the color of cement road is gray and white, which gives people the impression that there is insufficient buoyancy and no landscape. Therefore, when designing the main roads and secondary roads in residential areas or municipalities directly under the central government, if you want to get a better grade, you should choose asphalt pavement.

3. Disadvantages. Asphalt is easy to age, and the pavement color is dark and easy to absorb heat, resulting in a certain degree of dissolution. But you can use modified asphalt, and these problems can be solved to some extent.
