A study on freezing depth of concrete pavement
In this study, the freezing depth of concrete pavement was measured. Furthermore, the freezing depth was estimated from the modified Berggren equation used for estimating the freezing depth in pavement design in Japan. Then, the measured value and the estimated value were compared. As a result, it was clarified that there is a possibility of designing on a dangerous side in an area with a freezing index of less than 350 ° C / days.
