Zhejiang Daily News （Reporter Fu Yingjie Sharing Alliance·Dongyang Li Lei correspondent Liu Ning Jiang Mengfan） Recently，Dongyang Section of National Highway 351，A car printed with“Three-dimensional radar monitoring vehicles”One side of the SUV is driving slowly.，On the one hand, real-time physical examination of the road surface is carried out.。

“Three-dimensional radar monitoring equipment mounted on the vehicle，On the premise that the pavement structure is not damaged,，Collecting road surface smoothness、Various data such as thickness of foundation asphalt，And analyze the abnormal points according to the radar map.，Accurate positioning of the diseased road section。”Liu, deputy director of Dongyang Highway and Transportation Management Center, said.，Application of 3D Radar Monitoring Equipment，Reduced pavement excavation，Maximum protection of the pavement structure，Thereby reducing aggregate、Asphalt、Consumption of mineral powder and other building materials。

Three parts of the highway depend on construction and seven parts depend on maintenance.。In recent years，Dongyang continues to explore new technologies、New equipment、New Technology、Application and promotion of new materials，Let Science and Technology Enable Highway Maintenance，Promote the high-quality development of highway maintenance in Dongyang。

In addition to relying on three-dimensional radar monitoring equipment，Precise positioning of pavement recessive disease，The new technology test of low-temperature modified asphalt alkali has also been carried out in Xiangyi Line of 527 National Highway.，Pavement technology with large gap pouring，Compared with the traditional process，This technology takes into account both the beauty and comfort of the pavement and the ability to resist deformation.，It has a significant effect on preventing ruts.。
