Recently，Hangjin BannerC049 Highway Maintenance Project Completed Successfully，This is the first one adopted in Hangjin Banner.UTOD-5. Highway maintenance engineering of high performance asphalt concrete ultra-thin overlay。

In order to adapt to the systematization of highway maintenance management in the new era、Specialization、Refinement requirements，The concept of green development runs through the construction of transportation infrastructure.，Focus on strengthening green and low-carbon technological innovation，Hangjinqi Transportation Bureau actively tries out new technology of highway maintenance engineering，For the first timeUTOD-Application of 5 technology in maintenance engineering。UTOD-5. After molding, it has strong anti-rutting ability at high temperature.、And that low-temperature crack resistance is excellent、Ood impermeability and antiskid performance、Reducing road driving noise and the like.。

It is understood that，UTOD-5 Technology successfully applied toCMaintenance of Highway 049，It will reduce the looseness of the road surface after the heavy vehicles transporting agricultural materials.、Pavement diseases such as potholes，Can prolong that service life of the pavement，It can provide more comfort for the masses.、Safer travel environment。
