    Abstract
  • The reason was analyzed that the repetition times of axle load were larger resulted from the coefficient of wheel tracking transverse distribution, the concept of pass-to-coverage ratio was introduced, and the calculation method of pass-to-coverage ratio was given in accordance with wheel tracking following normal distribution. The calculating method of effective tire width on flexible or rigid pavement was put forward, and the effect of stress or strain peak value on pass-to-coverage ratio was analyzed under the action of axle load. Taking heavy truck J6 and Delong 3000 acting on rigid pavement for example, single and mixture traffic volumes were calculated by using the method of pass-to-coverage ratio. Analysis result shows that the calculating result of axle load repetition times is right at peak value position under present specifications, but it reduces quickly away from peak value position. For single-axle double-wheel load of J6, the repetition times of axle load reduce by 50% under single traffic volume while loading position is 0.8 m away from peak value position. So the calculation method is more precise than present method.
