Advanced Spall Repair Methods and Equipment
A series of experiments were performed using five excavation methods on nominal 2-foot wide, by 2-foot long by 4-inch deep spalls. The objective of this research was to develop one or more methods that will allow field personnel to excavate and prepare a 2-foot wide by 2-foot long by 4-inch deep spall for placement of a rapid-setting repair material in fifteen minutes or less. A secondary objective was to correlate various excavation methods with a relative life expectancy of the repair. Each of the methods tested had a significant improvement in production rate over the 30-pound jackhammer. The most efficient method was the cold planer, which, on average, was approximately 58 percent more efficient than the jackhammer.
