Title: FIELD ANALYSIS OF RUTTING IN OVERLAYS OF CONCRETE INTERSTATE PAVEMENTS IN ILLINOIS

Availability: Find a library where document is available Abstract: Thirty-two overlay projects placed over portland cement concrete pavements were surveyed for the initial development of a comprehensive statewide pavement data base of which these overlay projects would be part. Ninety-two different uniform sections were visually surveyed to obtain performance data on the overlay projects. Design and construction data were collected for inclusion in the data base. The data were analyzed to develop regression relations between rutting and mixture properties of the asphalt concrete overlays. The analysis clearly shows the importance of material properties to the development of rutting, particularly the gradation parameters. Eleven of the projects were cored for structural testing in the laboratory. The structural tests clearly show that the resilient modulus and indirect tensile strength bear a strong relationship to the rutting that develops in the overlay during its life. The analysis in this paper clearly shows how a statistically sound examination of pavement performance can furnish data for an analysis that provides information that can be used to alter mix design and construction practices to address a specific problem. In this paper it is shown that permanent deformation can be controlled through proper material control; further, if the allowable limits on variability of the mixture coming out of the plant can be altered, performance can be altered. A judicious selection of median values and tighter plant control can reduce rutting potential.
