The Reliability Analysis and the Probability Distribution of Wheel Tracking Test of Asphalt Mixture

摘要

The "Shapiro-Wilk test method (W-test)" was applied to analyze the probability distribution of the wheel tracking test result of asphalt mixture. The wheel tracking tests were executed on samples made in lab and samples obtained from mixture plant, f The results indicated that the dynamic stability and relative deformation partly fitted normal distribution and totally fitted lognormal distribution. According to the theory of stress-strength interference, the reliability coefficients of high temperature performance indexes under different reliability and different variation were calculated, and on basis of corresponding specification, control criterions of high temperature performance for various highway grades were present.
