Breaking and Seating has been used extensively to rehabilitate portland cement concrete pavements. In areas where specific vertical tolerances must be maintained, several methods have been used - - tapering of the asphaltic overlay, removal of the portland cement concrete replaced by full depth asphaltic concrete, or milling of the existing pavement and reducing the asphaltic concrete overlay.

Research Report UKTRP-87-26, "Breaking and Seating of Rigid Pavements" was prepared as a final report for three studies and as an interim report for Federal Aid Research Task No. 28 and two other studies. This report serves to finalize Federal Aid Research Task No. 28
