CCCC Xizhu: smooth paving of asphalt upper layer test section of Wuwei Bid Section 10

The other day，Urumqi-Yuli Expressway undertaken by CCCC Xizhu Pavement Engineering BranchWYTJ-Smooth completion of paving of the test section of the upper surface course of Bid 10，It marks that Wuwei 10th Bid Project has formally entered the construction stage of asphalt upper layer.。

The total length of the pavement works of this section is 22.345Km，Adopt the highway standard，The design speed is 100-120Km/h。The test section of the upper layer of asphalt paved this time is the right side of the main line.YK199+550-YK199+Segment 050，500 meters long，Paving thickness 4cm，The paving width is 11..25m,A total of 590 natural gravels are pavedt,One Paver is the main input equipment.，3 double-drum Road Rollers，3 rubber wheels，10 dump Trucks，One Sprinkler，One loader。

In order to ensure the high-quality and efficient completion of the test section of the upper asphalt layer,，The project department has made careful planning.、Careful deployment，Paving the day before the construction technology、Test、Safe、Relevant personnel such as mechanical operators shall carry out technical disclosure of construction safety.，Ensure that technicians fully grasp the process flow of paving and rolling of the upper surface course、Control points and construction precautions。On the construction standard，Strictly control the mixing of mixture、Transportation、Spreading、Rolling、Detection and other links，Ensure that the upper layer of asphalt is paved in an orderly manner.，One-time molding。After paving is completed，Smoothness of the test section by field technicians and laboratory personnel、Water Penetration Coefficient、Coefficient of friction、Compactness、Thickness and other indicators were tested.，All indexes meet the design and specification requirements.。    

The successful paving of the test section of the asphalt upper layer provides valuable and detailed technical parameters for the subsequent large-scale construction.。Wuwei Shibiao Team will go all out，Uphold high standards、Strict requirements，Continue to optimize the process，Improve work efficiency，Ensure that construction progress and quality go hand in hand，Escort the high-quality development of the branch。
