The present invention relates to a bride joint structure having an elastic joint member and a construction method thereof. The bridge joint structure includes a bridge concrete having an L-shaped cross section; 5 to 20 wt% of an elastic composition applied on the inner surfaces of the spaced bridge concrete and consisting of 30 to 40 wt% of polyol, 10 to 30 wt% of methyl methacrylate, 25 to 35 wt% of a filler, 5 to 15 wt% of calcium sulfo-aluminate, 2 to 6 wt% of a pigment, 0.5 to 5 wt% of defoamer, and 5 to 15 wt% of plasticizer; at least two elastic mortar consisting of 10 to 30 wt% of curable composition and 50 to 80 wt% of reinforced composition; and an expansion joint made of polyethylene foam to be inserted between the spaced elastic mortars. Shrink, expansion, and waterproof performances are provided in expansion clearances, without being affected by temperature change. |
