In August 2015, the Ministry of Transport of the People's Republic of China issued a new "Technical Rules for Construction of Highway Pavement Base", requiring that the mixing time of base pavement materials during the construction process of high-grade highways should not be less than 15 seconds. Based on this requirement, the secondary mixing type stabilized soil mixing station has begun to be promoted on the market.

Fangyuan Group has designed and developed the WBZ series two-stage parallel mixing stabilized soil mixing station, which can achieve rapid switching between primary and secondary mixing without any modifications to the equipment.

The WBZ series two-stage parallel mixing stabilized soil mixing station can be used for constructing high-grade highways and can also be applied to the construction of urban and rural roads. If secondary mixing of materials is not required, there is no need to partially disassemble the equipment to avoid additional operating costs.
