<p>PROBLEM TO BE SOLVED: To provide the embedment type joint part structure of a bridge capable of holding a water stopping function in a long term while satisfactorily absorbing the expansion/contraction displacement of a bridge and the construction method of the embedment type joint part structure.SOLUTION: An embedment type joint part structure of a bridge is configured of: a first bridge member 12; a second bridge member connected to the first bridge member 12, that is, a second bridge member 14 facing via an expansion gap 16 between itself and the first bridge member 12; a recess 18 formed along the expansion gap by notching long the opposed upper parts of the first bridge member 12 and the second bridge member 14 in an opposed line direction between the first bridge member and the second bridge member; and a joint part 20 formed by filling a bonding material 22 in which an aggregate is mixed with an elastic binder having elasticity after solidification in the recess 18 in an embedding state for absorbing the expansion/contraction displacement of the bridge members 12 and 14. The aggregate of the bonding material 22 contains a flat aggregate 38 of 8 to 15% in a weight ratio to the whole aggregate.</p> |
