ROAD REPAIR COMPOSITION

摘要

The present invention relates to a road repair composition. The road repair composition is prepared by mixing 79-85 parts by weight of a silica mixture, and 15-21 parts by weight of a polyurea epoxy composition. The silica mixture is prepared by mixing 41-48 parts by weight of SiO_2 powder, 20-24 parts by weight of silica sand No. 5, and 28-40 parts by weight of silica sand No. 3. When used to repair a road, the road repair composition is cured within a short period time after the repair work, thereby reducing duration of the repair work. Also, the road repair composition is well cured at a low temperature by using the polyurea epoxy composition which is a rapid hardening polymer, and has enhanced strength and durability.
