This paper presents six types of accelerated aging tests that were implemented so as to research environmental deterioration characteristics of rubber materials for bridge bearings. For quantitative evaluation of deterioration of the rubber, heat oxidation, ozone, low temperature ozone, ultraviolet rays, salty water spray cycle system and acid water spray cycle system were considered. It was found that the damage due to the heat and the ultraviolet rays deterioration was severer than the other factors of deterioration.", "subitem_description_type": "Abstract"}]},
