The test road is paved with a total length of 1000m.，Thickness of upper layer of asphalt concrete: 4cm，To ensure the paving quality，The project is carefully planned、Efficient organization，Applying information monitoring means to correct deviations from time to time，Arrange in advance the material preparation for the paving of the test road、Vehicle transport、Quality requirements、Security management、Logistics support，Safety technical disclosure before paving，Execute in strict accordance with the requirements of construction design specifications，Meanwhile, the owner、Supervisor、A third party、On-site guidance and supervision by the pavement consulting team and other personnel of Jiaotong Group，Strictly control the mix proportion of asphalt mixture、Paving temperature、Paving speed、Rolling process and times。Tested，The paving quality of the asphalt upper surface layer is excellent。

In view of this year's comprehensive pavement project，Implementation management of Baping Expressway、Three Paths of Technology and Informatization，In green、Durable、 Demonstration 、Technology is the goal，Actively explore the management methods and technical measures to improve the quality of three-lane large-section pavement in Guangxi.。

Management first，Quality improvement。In the planning stage of pavement engineering，The headquarters has set up a road surface demonstration creation center and included design.、 Consultation 、Pavement construction management team including inspection，Overall lifting and construction process management and control for pavement construction technology。

Innovative ideas，Technical support。Pavement Construction Experience of High-grade Highway and Distribution of Road Construction Materials in the Joint Area of Baping Expressway、Availability，Follow safety、Cozy、Environmental protection、Economy、Durable、Adjust measures to local conditions、Reasonable selection of materials、Principle of convenient construction，Insist on needs and goals to guide design，Take the durability of pavement quality as the core，Implement the whole life cycle design concept，Highlight the service life and durability of pavement engineering，Pay attention to the stability of pavement structure，Build“Flat、Cozy、Durable”Pavement works。

Technology push，Intelligent control。Adopt construction information monitoring system，Relying on the Internet of Things and cloud computing technology，Use the way of intelligent control，Improve the shortcomings of traditional management and control methods，Achieve real-time transmission of engineering data，Data association analysis、The goal of intelligent early warning。By monitoring and storing the real-time production data of the mixing station、Timely SMS alarm correction；Monitor the loose laying thickness、Paving temperature、Paving speed、Compaction temperature、Compaction speed、Compaction times, etc., and accurate display of data，The remote digital dynamic monitoring of each link of pavement construction is realized.，For the reference of managers.，Ensure effective management and control of construction technology。

At present，Baping Expressway is seizing the golden period of dry season，Carry out pavement construction on a large scale，Pavement Finished Bedding 84%、Subbase 74%、Base 55%、Topcoat 21%，Strive to achieve the goal of opening to traffic by the end of this year。
