The design and construction manual of concrete pavement in Japan introduces standard thicknesses of concrete slab ranging from 15 to 30cm, that are based on the analytical design method proposed by P. W. R. I. almost 20 years ago. The analytical design method is to determine a slab thickness based on the fatigue, which is computed by the magnitude as well as the number of the repetition of the resultant stress of wheel load stress and thermal stress.
This paper reports the performance survey of experimental concrete pavement sections of Yaita Bypass, which was constructed in 1968.
Useful findings of the survey are 1) the effectiveness of the use of asphaltic mixture on the top of base course, 2) the proposal of the use of strong dowel bars, 3) the possibility of transverse joint edge approaching the critical instead of longitudinal edge etc.
