Why do you want to brush a layer of red paint (paint) on the newly paved asphalt (asphalt) pavement?

This is a kind of flexible paint, which is mainly used as a sign to distinguish lanes. Usually elastic polyurethane or elastic epoxy resin.

Asphalt pavement does not need to consider joint crack prevention, but it will pollute the land and groundwater around the highway. The natural decomposition and degradation of asphalt takes decades, and the cost of asphalt pavement is more expensive than that of cement pavement. Compared with cement pavement, asphalt pavement is more convenient to maintain and faster to open to traffic, but the maintenance cost is high.

Under the same flatness level, asphalt pavement is more comfortable than cement pavement, and the operation economy of cement pavement is better than asphalt pavement. On the general expressway, when the speed is 60 km/h, the fuel consumption of cement pavement is 8% lower than that of asphalt pavement. When the driving speed is 120km/h, the oil consumption of cement pavement is 15% less than that of asphalt pavement.

Extended data

The 4.2 km section from Qianmen Street of Yuegui Road to the west section of Guangqumen Bridge has been overhauled, and the "disease" can no longer be seen on the newly paved asphalt pavement.

As a traffic artery that can be directly connected with the refractive road to the sub-center of the city, Guangdong-Guangxi Road starts from the west side of Guang 'anmen overpass in the west and ends at Guangqumen overpass in the East Second Ring Road, with a total length of 8.68 kilometers. It consists of five roads: Guang 'anmen Inner Street, Romanesque Street, zhushikou West Street, zhushikou East Street and Guangqumen Inner Street.

In 20 18, Liangguang Road started a three-year overhaul plan, and in that year, it completed the overhaul of Guang 'anmennei Street, Romanesque Street and zhushikou West Street. The overhaul of zhushikou East Street, Guangqumen Inner Street and Guangqumen Overpass will be completed in 20 19 and 2020 respectively.

"This time, the west section of Qianmen Street to Guangqumen Bridge of Guangdong-Guangxi Road was overhauled, namely zhushikou East Street and Guangqumen Inner Street. The total length of the route is 4.2 1 km, and the total planned maintenance area is about 240,000 square meters. "

Cai Shuoguo, vice president of Beijing Teshida Traffic Survey and Design Institute Co., Ltd., the designer, told the reporter that as the main roads of the city, the traffic volume of zhushikou East Street and Guangqumennei Street is not small every day, and rutting and road network cracking are more serious, especially at intersections. In order to eliminate the "diseases" on the road surface, and with the improvement of the urban environment in the east and west, the overhaul of Yuegui Road began.
