Zhengzhou Yifan Machinery has provided several sets of basalt plastic, machine-made sand production line produced by the mechanism of high-quality basalt and sand aggregate in the Shenyang-Dalian Highway SMA Pavement been widely applied
Stone Mastic Asphalt(SMA) is a mixture of the English name of the abbreviation. As the Shenyang-Dalian using SMA pavement technology, so Shen-Da-quality experts say the road could be comparable with the Beijing airport runway.
Shenyang-Dalian highway across the board the first line of the road across the country using SMA Pavement Technology, the technical requirements of the surface layer across the board with SMA-16L structure, which uses basalt coarse aggregate, fine aggregate sand all the use of mechanisms for graded aggregate and grain shape have raised a very high demand.
Zhengzhou Yifan Machinery Co., Ltd. provides a mechanism for sand production line to produce a mechanism for sand and powder to make the completion of the Shenyang-Dalian own contribution. The production line can also be used for shaping and production of basalt aggregate synchronization required for gravel aggregate seal coat.
