Abstract
To prevent a pumping phenomenon at joint of airport PC pavement, we developed structure that reduces deflection difference between joint sleeper slab and both PC slab and buffer slab by connecting these slabs by the bolts. In this study, Static Load Test and Wheel Running Test were carried out to verify the space between bolts and the connection force by the bolts, and Slide Test was also carried out to confirm the effect of connecting slabs by the bolts on axial displacement of slabs due to variation of temperature. As a result, we confirmed experimentally that connecting joint sleeper slab with PC slab by the bolts reduced the opening between these slabs, and a pumping phenomenon was hard to occur.
