Structural Overlay Strategies for Jointed Concrete Pavements. Volume 2. Cracking and Seating of Concrete Slabs Prior to AC Overlay
A major field study and evaluation has been conducted into the effectiveness of three structural overlay types for portland cement concrete (PCC) pavements. These include sawing and sealing asphalt concrete (AC) overlays of PCC pavements, cracking and seating PCC pavements prior to AC overlay, and constructing a thin bonded PCC overlay on top of the existing PCC pavement. Condition surveys, deflection testing, and roughness measurements were performed on a total of 55 sections. The performance of these sections was evaluated and the effectiveness of each overlay type analyzed. Based on the field data, guidelines were developed for the use of structural overlays. In addition, the results of the study were used to revise and enhance the EXPEAR rehabilitation advisory system. The volume examines the rehabilitation technique of cracking and seating PCC pavement prior to overlay, which has been used to reduce reflection cracking. Cracking the slabs reduces slab movement due to temperature changes; seating the slabs stabilizes the pieces. The first part of the report examines the literature and evaluates the performance of inservice crack and seat overlays from several States; the second part incorporates these research findings into guidelines for crack and seat techniques and specifications.
