PURPOSE: A composition for repairing roads and a road repairing method using the same are provided to shorten periods required for construction and curing by mixing a mixture composed of an organic resin and a curing agent with aggregate with different particle sizes. CONSTITUTION: A composition for repairing roads includes an organic resin and a curing agent. The organic resin is based on 50-80 parts by weight of an epoxy resin, 8-10 parts by weight of a reactive epoxy diluting agent, and 50-70 parts by weight of a urethane resin. The curing agent is based on 60-90 parts by weight of a curing resin. The curing resin is selected from a group including a polyamine resin, a polyamide resin, polymercaptan, and the mixture of the same. The mixing ratio of the organic resin and the curing agent is 1.5-2.5 : 1 based on volume. The composition further includes aggregate. The mixing ratio of the aggregate and the organic resin is 6-7 : 1 based on volume. The aggregate is based on 3-5 parts by weight of aggregate with 10mm particle sizes, 30 parts by weight of aggregate with 5mm particle sizes, 25 parts by weight of aggregate with 2mm particles sizes, 5-10 parts by weight of aggregate with 1mm particle sizes, and 30 parts by weight of aggregate with 0.6mm or less particle sizes.
