May 14，The test section of asphalt concrete middle surface course of Shijiazhuang Fuxing Street Municipal Reconstruction Project contracted by Pavement Engineering Branch is located inK19+510～K20+Successful paving of the right part of Section 210，Only ten days have passed since the paving of the test section of the lower layer of asphalt was completed.。

The whole test section is 700 meters long.，Design and useSBSModified asphaltAC-20CAsphalt concrete，Single width paving with 3 Vogler wide width anti-segregation pavers，Paving thickness 6cm，The paving area is 15500㎡。

In order to ensure the success of one-time paving of the test section of the asphalt concrete middle surface course,，The project department is in human resources、Material resources、Machinery and equipment are highly valued.，To site management personnel prior to commencement of construction work、Construction technicians、Operators and other relevant personnel conducted a thorough test and standardized construction training.，A scientific construction plan has been worked out.。During the paving of the test section，Asphalt mixture mix proportion gradation and material transportation、Paving temperature and construction elevation of asphalt material、The loose paving coefficient and rolling process are strictly controlled.。After paving is completed，Detect each data，The results of the test data show that，All the test indicators meet the requirements of the specification.。This successful paving not only provides various technical parameters for the large area construction of the middle layer of asphalt concrete,，It also sets a benchmark for other projects to continue standardized construction.。
