Abstract
A total of thirty-seven bench top tests were conducted. The experimental results indicate that crack width, aggregate type and gradation are the major factors influencing behavior. The surface roughness characteristics for all the joint types tested were successfully measured using digital image analysis. An analytical model for predicting the monotonic and cyclic behavior of the river gravel joint of large crack width is developed. An significant finding from this study is that it is unlikely that fatigue failure of an aggregate interlock joint will occur during the service life of the airport pavement for the specific type of joint tested, even for a crack width as large as 0.08 inch.
