According to one embodiment of the present invention, semi-rigid pavement for a vehicle comprises: open graded asphalt concrete including aggregates with a particle size and a sieve passing rate of a predetermined level; and cement milk injected into an opening of the open graded asphalt concrete. The cement milk is formed by mixing fly ash and silica fume with Portland cement, wherein 14 to 16 parts by weight of fly ash and 2 to 4 parts by weight of silica fume are mixed with 100 parts by weight of Portland cement with respect to 100 parts by weight of Portland cement. Accordingly, the cement milk having the Portland cement, the fly ash, and the silica fume mixed therein is injected into the open graded asphalt concrete with an improved particle size of the aggregate such that the semi-rigid pavement, in which the open graded asphalt concrete and the cement milk are integrated with each other, is formed, thereby improving durability and plastic deformation resistance in comparison with ...
