Successful implementation of heavy rutting modified pavement treatment technology in Changzhou, Jiangsu Province: application of cold method high modulus pavement National Engineering Research Center

In order to solve the problem of serious rutting of heavy traffic pavement,，October 2024，The National Engineering Research Center for Highway Maintenance Equipment has worked closely with the Construction and Transportation Bureau of Changzhou Economic Development Zone in Jiangsu Province.，Heavy traffic in and around the Beijing-Hangzhou Canal Bridge、The modified pavement treatment technology has been successfully implemented in the heavily rutted road section.。Application of this Cold High Modulus Modified Pavement Technology，It not only significantly improves the shear resistance and bearing capacity of the pavement.，It also provides a new technical demonstration for the efficient maintenance of heavy traffic sections.。

Modified paving technology is a kind of technology that does not need heating.，A New Method of Deep Activation Treatment for Old Asphalt Concrete Pavement Material。Through this process,，In-situ composite cementitious material（MOHMaterial）As a facing material。This powerful homogenizing composite cementitious material is compatible with traditional cold recycling materials.“Sandwich”The combination form is quite different，Its unique feature is that the material modulus can be adjusted according to the actual needs.，And the complete recycling of the old material resources is realized.。The technology is particularly suitable for the upper surface of the road and for bearing heavy traffic、Pavements with high requirements for shear rheology resistance。

The successful application of the modified paving technology，It is a breakthrough in the bottleneck of material technology of the National Engineering Research Center for Highway Maintenance Equipment.、Research and development of special Milling Machine、The achievements of scientific research in many aspects, such as the innovation of complete sets of equipment for continuous paving and the research and practice of combined construction methods, are concentrated.。Integrated application of these results，It not only improves the efficiency and quality of pavement maintenance.，It also provides a strong support for the sustainable development of China's highway maintenance industry.。

In order to further promote the modified pavement technology，Gaoyuan Road Industry Information Center is producing a detailed introduction video.，For academic and industry friends in-depth understanding，Experts, scholars and colleagues in the industry are welcome to put forward valuable opinions.。
