Abstract

The calculation model of the shrinkage stress of semi-rigid base course was established. By analyzing the stressing status of the tiny element in the model, the correlative formulae were founded, and the expression of the shrinkage stress was deduced. The maximum value of the shrinkage stress of semi-rigid base course was calculated and the position of the maximum value was presented. Besides, the influencing factors of the maximum value of the shrinkage stress were analyzed.
