Abstract
To analyze the characteristics of the longitudinal profile affected by frost heave, the longitudinal profile of an expressway in a cold region of Japan measured weekly from February to April of 2000 and from January to May of 2001 was analyzed. It was found that the increasing speed of winter IRI in cut segment greatly depended on the freezing speed and the maximum increment of winter IRI related to the maximum height of cut. The analysis of wave characteristics of the longitudinal profile showed that the content of long wavelength (>5.7m) was increased by the frost heave and its increasing speed was greatly affected by the freezing speed. It was also shown that the increase of wavelength 5.7-22.6m content due to frost heave caused an increase of dynamic load and the IRI in winter.
