The invention provides a technique for producing a coating surface layer for a skid resistant polyurea terrace, which aims to solve the skid resistant problem of the prior smooth polyurea terrace, and comprises the following steps: spraying polyurea on a substrate to form a uniform polyurea elastic body base layer; and evenly paving quartz sand particles on the uniform polyurea elastic body base layer when the uniform polyurea elastic body base layer is not solidified completely so as to form a quartz sand particle skid resistant layer. The obtained coating surface layer for the skid resistant polyurea terrace has good skid resistance, can ensure that the surface is nonskid in the rain, after the rain or in a humid environment, and has the advantages of good elasticity, comfortable foot feeling, no joint seam, easy washing, beautiful appearance, durability, wear resistance, aging resistance, and environmental protection. The technique for producing the coating surface layer for the skid resistant polyurea terrace can be widely applied to the ground surfaces of a playground, a tennis court, a basketball court, a badminton court, a gymnasium, a swimming pool, a production department, a hospital, a parking area, a parking lot and the like.

The invention discloses a method for treating the reflective cracks of asphalt pavement, which determines the cracking degree of the cracks in the pavement base. Then the backfill material of corresponding type is selected for filling and strengthening based on the cracking degree of the road base; And then laying anti-crack stickers on the road base layer in turn, viscous oil, synchronous crushedstone seal, The asphalt pavement surface layer is simple and quick. Because the asphalt pavement surface layer is paved with anti-crack sticking, sticking oil, synchronous crushed stone sealing layerand asphalt pavement surface layer after filling the pavement base layer, the asphalt pavement base layer cracking can be effectively treated, the continuous development of the emission cracking canbe restricted, the water damage of the roadbed can be reduced, the service life of the asphalt pavement can be prolonged, and the maintenance cost can be reduced.

The invention discloses a composite solid waste pavement base binder and a preparation method thereof, and belongs to the technical field of road engineering. The composite solid waste pavement base binder is prepared by mixing pretreated alkaline ardealite powder, fly ash, slag powder and cement. The industrial waste phosphogypsum slurry raw material is subjected to alkaline pretreatment to obtain the alkaline phosphogypsum powder, the alkaline phosphogypsum powder is mixed with the solid waste such as the fly ash and the slag and the cement, and the mixture is applied to a semi-rigid base material to be used as a gelling binder, so that an effective utilization way of the industrial waste residue material is provided, and the utilization rate of the industrial waste residue material is increased. Moreover, the resource utilization rate of industrial waste residue materials can be increased, and the problem of environmental pollution caused by stockpiling and discharging of industrial waste residues is solved. And the prepared pavement base binder can improve the strength of the pavement base, reduce the shrinkage cracking effect of the pavement base, reduce the cement consumption, reduce the cost, and achieve the purposes of recycling solid wastes, and being economical and environment-friendly.
