Abstract:Pavement structure, condition ratings, and distress were used to characterize the performance of rigid pavements in Oregon. Data from jointed and continuously reinforced concrete pavements ranging in age from 2 to 32 years were collected. Sixty-two experimental sections were identified along Interstate routes representing the range of environmental conditions in Oregon.
All Oregon rigid pavements are performing very well structurally. Older pavements have carried 2 to 6 times their design traffic, yet maintain serviceability issues above 3.0. Distress types commonly associated with the need for rehabilitation were not generally evident. Efforts to predict pavement distress development with structural, environmental, and loading data were unsuccessfully.
