Asphalt Concrete Overlay Design Methodology for

Little technical information or guidance is presently available for engineers to properly design asphalt concrete (AC) overlays over existing PCC pavements that have been fractured to minimize or eliminate the problem of reflective cracking. Such construction techniques as crack and seat, break and seat, and rubblization have been used by the industry at an increasing rate over the last 10 years. However, most design procedures have been highly subjective, extremely conservative, and based on a lack of engineering principles related to the actual construction process used as well as an accurate assessment of the in situ physical properties of the fractured slab. To improve the state of the art and develop a better understanding of these rehabilitation techniques, a nationwide evaluation study of these rehabilitation types was conducted. The study led to the field evaluation of performance and structural in situ properties of more than 100 actual construction projects where these techniques had been used with AC overlays. On the basis of the study results, design procedures were developed for highway pavements and are presented. The design procedures are based on the flexible pavement performance methodology
