Breaking and Seating has been extensively utilized to rehabilitate portland cement concrete pavements. Relationships have been developed to determine effective fragment size based on effective modulus of the broken portland cement concrete. Based on this relationship, the effective size of broken segments is on the order of 30-90 inches in the inside lane and 6-15 inches in the outside lane.

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. 27 and two other studies. This report serves to finalize Federal Aid Research Task No. 27
