Abstract

Strength of cement stabilized macadam which added early strength agent improves quickly. This shortens the construction period of road maintenance. This study explores the difference of fatigue performance between the cement stabilized macadam which added early strength agent and the ordinary cement stabilized macadam. Test fatigue lives under different stress levels. These fatigue lives in line with double-parameter Weibull Distribution. Then determine the two parameters of Weibull Distribution. On this basis, establish the fatigue equations of each early strength agent amount and determine the regression coefficients. The results show that early strength agent can improve fatigue life of cement stabilized macadam, but it makes cement stabilized macadam become more sensitive to stress level.
