EXPANSION JOINT STRUCTURE FOR FIELD-MOLDING OF ELASTIC PAVEMENT MATERIAL OF ROAD STRUCTURE USING SUPPORT PANEL AND REINFORCEMENT GRID AND EXPANSION JOINT CONSTRUCTION METHOD
Disclosed is an expansion joint structure for on-site forming of an elastic pavement material of a road structure using a support panel and a reinforcement grid, which can enhance the durability of an expansion joint. The expansion joint structure for on-site forming of an elastic pavement material of a road structure using a support panel and a reinforcement grid, wherein a cutting unit is formed on an upper part of an interval of a road structure, in which a road pavement material is spread on an upper part of a plurality of concrete structures spaced apart from each other at a certain interval, and an elastic pavement material is filled in the cutting unit, comprises: a support panel which is disposed on the upper part of the interval and is made of butyl rubber-impregnated non-woven fabric; a first elastic pavement layer on which the elastic pavement material is disposed to be filled and tamped on the upper part of the support panel and the interval at a certain thickness to cover the support panel; a reinforcement grid which is disposed on an upper part of the first elastic pavement layer while forming a U-shaped section structure to cover both side walls of the cutting unit and the first elastic pavement layer; a second elastic pavement layer on which the elastic pavement material is disposed to be filled and tamped on an upper part of the reinforcement grid to cover the reinforcement grid; and a surface coating layer which covers the second elastic pavement layer.
지지패널과 보강그리드를 이용한 도로구조물의 탄성포장재 현장성형용 신축이음구조가 개시된다. 상기 지지패널과 보강그리드를 이용한 도로구조물의 탄성포장재 현장성형용 신축이음구조는, 서로 일정 간극 이격된 복수개의 콘크리트 구조물 상부에 도로포장재가 도포되어 이루어진 도로구조물의 상기 간극 상부에 절단부를 형성하고 상기 절단부에 탄성포장재를 충진하여 구성되는 도로구조물의 신축이음구조에 있어서, 상기 간극의 상부에 배치되며, 부틸고무가 함침된 부직포로 이루어지는 지지패널; 상기 지지패널을 덮도록 상기 간극 및 상기 지지패널의 상부에 탄성포장재가 일정 두께로 충진 및 다짐되어 배치되는 제1 탄성포장층; 상기 절단부의 양측 측벽 및 상기 제1 탄성포장층을 덮도록 U자 형상의 단면 구조를 이루면서 상기 제1 탄성포장층 상부에 배치되는 보강그리드; 상기 보강그리드를 덮도록 상기 보강그리드 상부에 탄성포장재가 일정 두께로 충진 및 다짐되어 배치되는 제2 탄성포장층; 및 상기 제2 탄성포장층을 덮는 표면코팅층을 포함하는 것을 특징으로 한다.
