New maintenance technology will save 400 million RMB each year in Chongqing

Under the promotion of the Chongqing road maintenance center, the first case of  "Hot in place Recycling truck used in highway maintenance” demonstration was held in Banan district last month. From now on, 400 million RMB will be saved each year in road maintenance.

 Hot In-place Recycling truck looks like a train with 5 “carriages”; they are powder distributor, tank truck, Emulsified asphalt tank car, Cold material reclaimer and road roller. This maintenance truck will finish the pavement rehabilitation when it passing by the pavement. According to the description of Mr. He, the project director, doctoral tutor of Chongqing University of Communications, this “train” will firstly soften the old asphalt and recycle, and then mix the old asphalt with additive, and pave the new material on the highway. “We used to spend two day in paving one kilometer, but now only takes one hour.” He said. “Road maintenance cost in Chongqing each year is more than 1.5 billion RMB, the use of hot regeneration technology can save maintenance cost by 400 million.”
