Rubblizing Concepts—Heavy Load Concrete Airfield Pavements
Within the FAA Integrated Airport System airfield infrastructure and the U.S. Defense Department airfield inventory, there are more than 100 million square yards of heavy load concrete airfield pavements greater than 13 inches in thickness and more than 35 years old. These pavements will need major rehabilitation within the next 10 years. Traditionally, concrete pavement restoration (CPR) procedures (including techniques such as sub-sealing, full-depth patching, partial-depth patching, load transfer reconstruction, diamond grinding, and joint sealing) have been employed to maintain these pavements in a fair to good condition. These CPR procedures are becoming less effective today as the present pavement condition ratings are reaching a critical point where major rehabilitation is required. Rubblizing concrete pavement is becoming the paramount concrete pavement rehabilitating technique adopted by state highway agencies for heavy load highway pavements. From 1994 to 1998, states in the northeast, south and Midwest United States have rubblized concrete pavement and placed Hot Mix Asphalt (HMA) overlay over more than 20 million square yards of highways. An additional 25 million square yards of pavement were rubblized in 1999–2000 and overlaid with HMA (primarily Superpave). Most experience with the proven rubblization technique has been with concrete pavements of thickness between 7–10 inches. However, new concepts were employed to successfully demonstrate the rubblization technique on 14 inches of heavy load concrete airfield pavement at the Memphis International Airport, in July 1999. Information acquired during the demonstration at Memphis provided criteria to develop prototype resonant breaker equipment for heavy load concrete airfield pavement (in the 16 inches range). This paper presents the concepts associated with design, construction, and performance of hot mix asphalt (HMA) overlays placed on rubblized heavy load concrete pavements. Emphasis is placed on: 1) Side drains to insure free drainage; 2) Description of rubblization equipment and construction procedures; and 3) Design considerations for rubblization of concrete pavements.
