Now, with the renovation of the city center, many citizens are concerned about the "black and white" travel in urban areas, and the use of asphalt by cable asphalt manufacturers during travel may be harmful to human health. Now let's introduce natural asphalt pavement.

Asphalt can be divided into three types: coke asphalt, petroleum asphalt, and natural asphalt. Petroleum asphalt is the primary choice for journey manufacturing.

Petroleum asphalt is the residue of crude oil after distillation. According to the recovery rate, liquid, semi-solid, or solid will be produced at room temperature. Oil extracts black and shiny colors with high temperature. Because it is distilled to 400 degrees Celsius or higher during the production process, it contains very little volatile components.

The volatile components in evaporated petroleum asphalt require approximately 300 degrees Celsius. Laying asphalt on urban journeys, the construction temperature of asphalt concrete is around 150-170 degrees Celsius, which is much lower than the transpiration point containing volatile components. Even in the scorching summer, the journey of rubber asphalt after molding has a high softening point, and there will be no quality or quantity changes at normal temperatures, which meets the requirements of environmental protection and safety.

During the construction process of asphalt pavement, due to the impact of high temperature on odor, the cable asphalt manufacturer has little influence on the nearby construction workers. After forming, the temperature drops to normal. There is no statement about the presence of carcinogenic substances in asphalt, so asphalt continues to be widely used in waterproofing and travel engineering in developed countries. The use of asphalt in areas where there is no direct contact with the human body will not harm the health of users.

There are several benefits to asphalt pavement:

1. Asphalt pavement belongs to flexible pavement, with convenient transportation and low noise; Cement concrete pavement does not have asphalt pavement, and it requires 4-5 meters to adjust equipment expansion joints for cement concrete pavement, which also affects the comfort of sports.

2. The asphalt pavement construction should be completed before opening the traffic, usually several hours after laying, and can be opened for up to a day, while the cement concrete pavement requires a longer power supply period (during which water spray protection is required) before reaching the traffic intensity.

3. After partial damage to the asphalt pavement, repair is relatively simple and convenient, which affects the short travel time;

4. Asphalt pavement has a rougher surface and stronger skid resistance than flat cement concrete pavement. Vehicles are less likely to slide on rainy days and the braking interval is relatively short.
