The Prediction of Fatigue Life Based on Four Point Bending Test

To be able to devise optimum strategies for maintenance and rehabilitation, it is essential to formulate an accurate prediction of pavement life and its maintenance needs. One of the pavement life prediction methods is based on the pavement's capability to sustain fatigue. If it were possible to have a prediction that closely represent what is...

Estimation of fatigue characteristics of asphaltic mixes using simple tests

A simplified procedure for estimation of fatigue characteristics of asphaltic mixes is presented. The procedure requires the determination of the so-called master curve (Le. the relationship between the mix stiffness, the loading time and the temperature), the asphalt properties and the mix composition. It is shown that the master curve does not...
