Road repair new technology pavement repair farewell cumbersome      

Recently, in Zhuzhou Avenue pilot construction of the latest repair technology: just drill a small hole, you can put mud pressure into the gap under the road, complete subgrade repair. Zhuzhou Tianyuan district municipal engineering maintenance office staff said that after the successful pilot, the repair process is expected to be promoted in the region.

"In the past to repair the roadbed, first with the milling machine for deep planing, from pavement to dig the road base, to dig more than 50 cm deep, another layer to do." Tianyuan municipal department responsible person introduced, the use of new technology "trenchless grouting reinforcement technology", only in the need to repair the road, drilled a diameter of 5 cm of small holes, and then pressure grouting machine into the road with quick solidification of inorganic grouting material on it.

"Take the pilot repair road for example, Zhuzhou Avenue section of more than 250 meters of the road, before the repair may take nearly half a month, now only three or four days, and also had to dig the road, now only need to close a short section of the road on the line. It used to be about ten people to finish the work, now only four or five people on the line, convenient for passing vehicles." A road officer explained.

New pavement repair technology not only saves unnecessary trouble, reduces manpower and material resources, saves energy, more importantly, scientific and environmental protection, and adds a contribution to China's road career.
