Breaking and seating have been used extensively in Kentucky to rehabilitate portland cement concrete pavements. Experience over 3 or 4 years with this type of design and construction is summarized and reported. Breaking to a range of nominal fragments is evaluated, and a report on the evaluation of two roller weights for seating is given. Also described is the use of dynamic deflections to gauge the effectiveness of the breaking and seating process and to measure the appropriateness of the asphaltic concrete overlay.
