Deflection-Coverage Relationship for Flexible Pavements

A. H. Joseph / J. W. Hall

The study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield and highway data and for airfield data only. The relationship of wheel load and tire pressure is given, and a multiple-regression equation was determined to predict coverages as a function of wheel load, tire pressure, and deflection. (Author)
