According to the Desert Control Research Institute of Gansu Province, which developed the machine, the machine places checkerboard-type large straw nets on the surface of the desert to reduce the wind speed and fix moving sand dunes. The efficiency of the paving machine is estimated to be four to six times that of manual work and able to cover about 16 ha per day.
