1Â Â Proper maintenance and repair of concrete airfield pavements are critical to their longevity and ability to safely support airport operations over their design life. However, these activities can be costly and operationally disruptive, as they require closure of the pavement facility. To minimize the construction impacts, airports of all sizes are relying on rapid slab repair and replacement (RSRR) activities that include partial- and full-depth repairs (both partial- and full-slab replacements). Federal Aviation Administration (FAA) Advisory Circular (AC) 150/5370-16, Rapid Construction of Rigid (Portland Cement Concrete) Airfield Pavements (FAA 2007), addresses many key components and considerations for accelerated concrete construction but stops short of providing sufficient details or specific methods to aid airport personnel or consulting engineers in making informed decisions. Furthermore, AC 150/5370-16 focuses on larger areas of concrete replacement and provides only limited information on individual slab replacement or smaller repairs. In addition, FAA Item P-501, âPortland Cement Concrete Pavementâ in Standard Specifications for Construction of Airports (AC 150/5370-10H) (FAA 2018), does not provide specifications for construction featuring early-strength concrete or prepackaged repair materials used in RSRR projects. Major challenges to completing RSRR include stakeholder coordination, airfield closures, high construction costs, and lack of experience with early-strength concrete repair materials. While the necessary level of stakeholder coordination regarding airfield closures varies by airport size and function, high costs and lack of experience with these types of repairs are a universal challenge. Large hub airports have good experience with RSRR, and some have advanced programs in place. Importantly, elements of their RSRR programs and practices are easily applied by smaller airports (e.g., nonhub primary and general aviation) that are less likely to have RSRR experience. This guidebook was developed to assist airport personnel and engineering consultants in selecting and executing RSRR projects, and it provides relevant information for airport maintenance personnel performing RSRR work. It is based on a review of the literature, an online survey of airports, interviews with airport personnel and engineering consultants with RSRR experience, and site visits to observe and document important aspects of RSRR construction. Furthermore, this guidebook covers the overall RSRR process, including plan- ning, design, and construction. It builds on information provided in FAA AC 150/5370-16 (FAA 2007) and other relevant documents considered to represent current state-of-the- practice for RSRR. Ten case examples of RSRR practice and programs at airports across the country along with key takeaways from observing five RSRR construction projects are provided to illus- trate the guidance provided herein. Key technical documents are cited throughout the guidebook to provide additional resources and technical information. S U M M A R Y Rapid Slab Repair and Replacement of Airfield Concrete Pavement
