摘要：

In this paper, an energy criterion is suggested for determining the low temperature cracking frequency. And, in order to realize the criterion, a finite element method is developed for 1-demention thermal stress field in bituminous pavement. It can be shown by the verification of test road data that the criterion and method are very practical, not only the effct of surface course material but also that of structural factors on cracking frequency can be analyzed with this criterion.
