Abstract

 In this study, in order to apply the vehicle weight investigation results conducted by the Ministry of Land, Infrastructure, Transport and Tourism to the concrete pavement slab thickness design, the temperature measurement results of the concrete slab measured at 9-locations in Japan were analyzed to determine the time zone when the thermal stress is positive or negative, and extract the wheel load group passing at that time zone. And the effects of these results on the concrete slab fatigue damage calculation were investigated. As a result, it was found that the data of the wheel load and its action frequency collected every 12 hours in the vehicle weight investigation correspond to the time zone when the thermal stress is positive or negative, and can be used directly for the concrete slab thickness design. On the other hand, it was found that the fatigue damage level of the concrete slab when using the track traffic per day was estimated excessively according to the current design method.
