Abstract: On the basis of the investigations and measures of traffic Parameters,the distribution of total equivalent standardaxle loads over the pavement design pened are derived firstly. then the standard deviahon and variability are obtained.effects of traffic parameters to cavement depth design are analyzed. The results presented in thes peper are useful to fleasble pavement design haed on the reliability principles.
