Temperature effect on dynamic deflection of airport concrete pavement

Abstract

Abstract: To study the airport concrete pavement dynamic deflection behavior due to daily temperature variations, slabs in aircraft movement area are selected to test per hour one day. Relations between slab interior deflection, slab side deflection, slab corner deflection, load transfer efficiency and pavement surface temperature variations are analyzed respectively. Results indicate that slab interior deflection barely varied as temperature changed.Besides, side deflection, corner deflection, voids ratio are varied considerably as pavement surface temperature changes in a negative correlation. Meanwhile, the dummy joint pavement load transfer efficiency is affected by temperature significantly, and the tongue and groove joint pavement are almost unaffected.

Key words: airport, concrete pavement, deflection test, temperature effect, joint load transfer, void beneath slab
