Precast Slab Literature Review Report: Repair of Rigid Airfield Pavements Using Precast Concrete Panels - A State-of-the-Art Review

Abstract

Abstract : The ability to rapidly repair damaged airfield sections is of paramount importance. It is imperative to restore flight operations in the shortest possible time. Currently, there are several methods that pertain to expedient airfield damage repair. One method uses cast-in-place, high-early-strength concrete. The cast-in-place procedure entails completely removing the damaged portion of airfield pavement and subsequently placing fresh concrete into the resulting void. A second method involves the use of precast concrete panels. The precast concrete panel procedure requires removing a damaged section of runway and replacing the damaged section with one or more precast panels. Obviously, the removed damaged section and the precast section must be congruent. This report details the precast concrete panel repair method, including its advantages and disadvantages. Additionally, this report summarizes information on repairs using single precast panels and repairs using several connected precast panels. There are several different methods that utilize single panel and connected panel repair. The most common of these are the Fort Miller Super-Slab(registered trademark) Method, the Michigan method and the URETEK Method. Each of these options is discussed in detail.
