Odd! The old road "eats" in, the new road "spit" out!

Late on the night of August 5, on the Wangjiang East Road in Hefei City, a series of orange "trains" consisting of large blocks were moving slowly. Surprisingly, where the “train” went, the old damaged road was completely renewed.

Originally, this is an “international leading” road maintenance technology introduced by the Hefei Municipal Municipal Engineering Management Office Maintenance Company – Yingda Geothermal Recycling Process. This is also the first time Hefei City has adopted this rapid environmental protection process to maintain urban roads.

The old road "eats" in, the new road "spits" out

According to reports, the Wangjiang East route before construction was open to traffic for a long time, and the traffic volume was large, causing aging, cracks, rutting and other diseases.

This set of Indah's in-situ thermal regeneration process is zero-rounded and consists of a unit. After the unit "one" line was put in place, the construction officially began.

The unit sprays regenerant and new asphalt on the road surface, and supplements a small amount of new materials.

New road "spit out"

The unit heats, loosens, sprays regenerant and new asphalt on the road surface, and then adds a small amount of new materials, mixing, paving and rolling. Facing the Wangjiang East Road, which is in urgent need of cure, the whole unit is like a slow-moving train, slowly moving forward, and behind the unit, a new road has been reproduced.

Because the construction takes the assembly line operation, the degree of mechanization is high, the construction speed of the unit can reach 4 m / min, and the construction efficiency is more than three times higher than the traditional process in the past. The entire construction site is neat and orderly.

Pipeline operation, high degree of mechanization

Environmentally friendly and efficient, the construction impact is reduced

By maintaining roads in this way, economic, efficient, fast, environmentally friendly, economic and social benefits are mutually beneficial.

It is estimated that compared with the traditional asphalt road maintenance method, the maintenance of Wangjiang East Road has reduced the discharge of nearly 2,000 tons of waste asphalt mixture. At the same time, the complete use of waste saves about 1,500 tons of new asphalt mix, saving resources.

The construction of Wangjiang East Road is located in the “Heart” section of Hefei City. Due to the single-lane construction, there is no need to close the entire road, and the remaining lanes can pass normally, minimizing the impact of construction on public travel.
