PURPOSE: An epoxy resin composition for waterproof bonding of pavement material is provided to reduce tensile deformation, while having high complex modulus, and waterproofness of a packing matearil, because of increased adhesion strength and elongation of an adhesive surface, and to improve lifetime of a road, because of integrated new and old pavements. CONSTITUTION: An epoxy resin composition comprises a based material and a hardener with the weight ratio of 1:0.5-2. The base material comprises 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bisoxirane homopolymer in chemical formula 1, and 5-15 weight% of [(2-ethylhexyl)oxy] methyl oxirane in chemical formula 2. The hardner comprises 60-80 weight% of aminododecane in chemical formula 3, 20-40 weight% of hydroxy-terminated 1,3-butadiene homopolymer in chemical formula 4. |
