This semi-flexible pavement requires fluid resistance, oil resistance, heat resistance, light color, etc.For example, intersections of roads where vehicles are frequently braked, stopped, started, bus stops, highways Toll booth,
Used for gas stations. The construction of the semi-flexible pavement is performed by paving an open asphalt mixture having a large porosity of about 20 to 27% as a base material, and then infiltrating cement milk for infiltration into the open asphalt mixture as grout. The curing time until the opening of traffic after infiltration is about 3 days when using ordinary Portland cement as cement, and about 1 day when using early-strength Portland cement. It takes about 3 hours in the case of using a material to which a hardener is added. This cement milk for infiltration is added to a powder of cement, silica sand or the like while stirring a mixed solution of water-based resin emulsion or rubber latex and water at a construction site in advance, and uniformly kneaded by a mixer.

Also, even if the worker is immature, there is no possibility of mis-mixing. In addition, the bleeding rate of the cement milk for infiltration can be reduced, the fluidity is excellent, the drying shrinkage can be reduced by lowering the water powder ratio, and the strength expression is excellent. Further, the drying shrinkage of the cement milk for infiltration can be reduced, whereby the occurrence of cracks can be suppressed, and the scattering of dust at the time of construction can be prevented.
