Coral sand hydraulicity road base, road base material and preparation method thereof
The invention discloses a coral sand hydraulicity road base, road base material and preparation method thereof, and relates to the field of a road engineering construction. The preparation method of the road base material comprises the following steps: measuring 80 to 95 percent of coral sand and 20 to 5 percent of ordinary Portland cement, uniformly mixing and stirring the coral sand and ordinary Portland cement to obtain a primary mixture; then measuring 99.5 to 99.95 percent of the primary mixture and 0.5 to 0.05 percent of coral sand hydraulicity curing agent, uniformly mixing and stirring the primary mixture and coral sand hydraulicity curing agent to obtain a pre-mixed material, and controlling the water content of the pre-mixed material at 6 to 8 percent; the coral sand hydraulicity curing agent is formed by mixing the following components: 40 to 60 percent of elastic styrene-acrylic latex, 30 to 20 percent of nano aluminum sol and 30 to 20 percent of nano silicon sol, and the solid content of the elastic styrene-acrylic latex is more than 55 percent. The road base is formed by adopting the road base material according to a standard road base construction method. The coral sand is used for producing the road base material, thereby tailoring measures to suit local conditions; the formed road base is high in crack resistance, unlikely to corrode and long in service life.
