Abstract
It is needed to consider both loading stress due to aircraft load on concrete slab and thermal stress due to temperature change of concrete slab in design of airport concrete pavements. However, thermal stress is just considered by safety factor in present empirical concrete design method. For the purpose of clarifying thermal stress of airport concrete pavements, experimental pavement was constructed, and then, strain and temperature in concrete pavement were measured. As a result, it was clarified that thermal stress of airport concrete pavement was smaller than that of road concrete pavement, and thermal stress formula for airport concrete pavement was proposed
