초록

Curling is caused by the difference in the temperature and humidity by the depth of the slab in Jointed Plain Concrete Pavement. Slab
curvature shape and size change due to curling exert a profound influence on the internal stress and roughness of the pavement, affecting
structural and functional performance of the pavement. Direct measurement of the slab curvature entails many problems. Many measuring
instruments have to be installed at the early-stage of the pavement construction, and the behavior of the slab curvature needs to be measured
accurately from the early-stage. Moreover, the cost and technical difficulty are very formidable to measure the slab curvature. This study
develops a measurement method for slab curvature in jointed concrete pavement at any given time by applying Power Spectrum Density
Analysis and Inverse Fast Fourier Transformation to the profile data, that can be easily obtained at the construction field site. The
effectiveness of this developed method is verified by measuring the profile data of the test road of jointed concrete pavement at an inland
central expressway by the hour and by examining the result of extracting the slab curvature shape from this profile data. Additionally, the
profile data of CRCP(Continuously Reinforced Concrete Pavement) sections on the same expressway were obtained and analyzed at the
same time. The validity of the method developed for the slab curvature shape extraction is verified by comparing the result from the analysis
of the profile data of CRCP sections with that from the analysis of the profile data of jointed concrete pavement sections.
