PLACING AGENT FOR EXPANSION JOINT IN ROAD AND CONSTRUCTION METHOD THEREOF
The present invention relates to mortar for a road expansion joint and a construction method thereof. More specifically, the present invention relates to mortar for a road expansion joint and a construction method thereof, which uses MMA mortar with elasticity as a binder to improve durability against repetitive impact loads caused by vehicle traffic, improves a waterproof property for preventing components such as calcium chloride from penetrating together with water, and enhances the adhesive force between the expansion joint and the mortar. The present invention comprises: a resin part including an MMA resin added in a proportion of 40-60 wt%, butyl methacrylate added in a proportion of 10-30 wt%, butyl acrylate added in a proportion of 2-8 wt%, 2-ethylhexyl acrylate (2-EHA) added in a proportion of 10-20 wt%, and a phthalate resin added in a proportion of 5-15 wt%; and a powder part including calcium carbonate added in a proportion of 20-30 wt%, silica added in a proportion of 40-60 wt%, aggregates added in a proportion of 18-28 wt%, and benzoyl peroxide added in a proportion of 1-3 wt%.
본 발명은, 40~60 중량%의 비율로 첨가되는 MMA수지와, 10~30 중량%의 비율로 첨가되는 부틸메타아크릴레이트와, 2~8 중량%의 비율로 첨가되는 부틸아크릴레이트와, 10~20 중량%의 비율로 첨가되는 2-EHA(2-Ethylhexyl acrylate)와, 5~15 중량%의 비율로 첨가되는 프탈산 수지(phthalate resin)를 포함하는 수지부; 및 20~30 중량%의 비율로 첨가되는 탄산칼슘과, 40~60 중량%의 비율로 첨가되는 실리카와, 18~28 중량%의 비율로 첨감되는 골재와, 1~3 중량%의 비율로 첨가되는 과산화벤조일을 포함하는 분체부를 포함하는 것을 특징으로 한다.
