May 18，The acceptance review meeting of the construction project of China Jiaotong Construction Asphalt Pavement Quality Monitoring Sub-Center, which was participated by Xizhu Company, was successfully held in Xi'an.。The acceptance expert group is led by Li Hao, General Manager of Safety Supervision Department of CCCC.，It is composed of a number of experts from various units within the group.。Deputy general manager of the company、Chief Engineer Zhang Yongwei，Shi Faken, Executive Director of the Institute, and members of the project team attended the meeting.。

The asphalt pavement quality monitoring sub-center is jointly constructed by CCCC Xizhu and CCCC Second Highway Engineering Co., Ltd.。Asphalt pavement quality monitoring system covers the whole process of pavement construction，Including tests、Mixing、Transportation、Spreading、Rolling and quality inspection and other key links。Through the pavement material、Production、All links of construction are networked for real-time monitoring.，That is, for asphalt、Key index test of asphalt mixture、Asphalt mixing plant、Transport vehicles、Paver、Networking of road rollers, etc.，Collection test、Production and construction data are uploaded to the monitoring system。Use of automated data processing、Analysis，Real-time reflection of monitored asphalt quality、Production quality of mixture mixing，As well as the quality of paving and rolling，Discovery and production process、 Standard 、Deviation from standard，So that that construction quality of the asphalt pavement is integrally control and improved。

The experts listened to the report of the undertaking unit.，Upon inquiry、 Discussion ，It is believed that the undertaking unit has completed the site construction of the asphalt pavement quality monitoring sub-center of China Jiaotong Construction and the research and development of the asphalt pavement monitoring system in accordance with the contract.，System soft、Hardware and site matching meet the functional requirements of the whole process monitoring of asphalt pavement construction quality.，With the support of the group's policy, the monitoring system was applied to six different projects for trial operation.，Through data collection of each project、Analysis、The feedback has achieved the expected results.，Meet the contract acceptance criteria，The project has passed the final acceptance。

The asphalt pavement quality monitoring sub-center will become a specialized organization for asphalt pavement quality supervision of the Group.，Provide professional quality and technical services for the quality supervision of asphalt pavement of the Group，To be responsible for the construction and application of specialized information system for asphalt pavement quality monitoring，At the same time, carry out professional analysis of big data.，Provide support for the improvement of quality and efficiency。
