Abstract

Many years ago faulted joints were recognized by Highway Engineers as a form of pavement distress which could substantially reduce pavement serviceability. Faulted joints can have many effects on the highway user ranging from riding discomfort to a safety hazard. As a result, considerable research has been done on the cause, physical action, and effect of joint faulting. A brief explanation of faulting is given in Appendix "A". No attempt will be made in this report to confirm or refute any research undertaken in the past. The report will, however, attempt to indicate the magnitude of joint faulting on Iowa's Primary Roads and recommendations will be made as to the validity of our present design standards for jointed pavements with or without load transfer devices in the transverse contraction joints.
