Phosphogypsum water hard road base, road base material and preparation method thereof
The invention discloses a phosphogypsum water hard road base, a road base material and a preparation method thereof, relating to the field of road engineering construction. The preparation method of the road base material comprises the following steps: weighing 85-92 percent of phosphogypsum and 15-8 percent of ordinary portland cement, uniformly mixing and stirring, thereby obtaining a preliminary mixture; weighing 99.7-99.95 percent of preliminary mixture and 0.3-0.05 percent of a phosphogypsum water hard curing agent, uniformly mixing and stirring, thereby obtaining a premix; controlling the moisture content of the premix to be 14-18 percent, thereby obtaining a base material, wherein the phosphogypsum water hard curing agent is prepared by mixing the following components in percentage by mass: 40-60 percent of elastic styrene-acrylic emulsion, 30-20 percent of nanometer alumina sol and 30-20 percent of nanometer silica sol. The road base is prepared from the road base material according to a standard road base construction method. The road base material is produced by utilizing phosphogypsum, the environmental pollution is reduced, and wastes are changed into valuable materials; and moreover, the formed road base is high in crack resistance, difficult to corrode and long in service life.
