For practical applications, full-scale test integral geosynthetic-reinforced soil (GRS) bridge, having a width of 3m, height of 5.55m, length of about 14.75m, was constructed. Aiming to measure variations in temperature and variations in the cyclic loading test on bridge girder, field observation has started. Measurement items are, stress of Geosynthetics, displacement between the end of bridge girder and backfill, vertical earth pressure on the bottom of the footing, horizontal earth pressure on the abutment, inclination of abutment, temperatures and reinforcing bar stress. From a 4 months measurement results, in response to seasonal variations in temperature, which also reacts the bridge. But, its variation is quite small. The integral GRS bridge, which length is around 15m, found to be stable enough to seasonal variations in temperature.
