Preventing Foreign Object Debris and Improving Pavement Life-Cycle Costs Through Effective Fast-Track Concrete Repair

The biggest challenge facing airports, is the need to ensure efficient operations including proper maintenance of the airfield pavements (i.e. runways, taxiways and aprons). In short, the study presents a methodology of assessing repair materials in terms of technical and economic factors. This research identifies economical fast track concrete material and construction methods suitable for partial depth repairs in the airport environment. Specifically, the research in this paper is directed at addressing various technical and economic concerns regarding the use of fast track concrete with harsh deicing chemicals and extreme weather conditions. It describes a field study which is located at Canada’s largest airport and North America’s fifth busiest airport. Seven test sections were repaired on Deicing Bay 2 at Toronto International Airport with three different fast track products. Fourteen pavement evaluations were completed between October 20, 2003 and June 2, 2006. Test section performance was evaluated using the Strategic Highway Research Project H-356 method. The Foreign Object Damage average values on June 2, 2006 were calculated as 19 for Product A, 20 for Product B, and 40 for Product C. The Product A test sections are performing the best and is the product of choice. Based on the developed linear regression models, test section 7 which is Product C will last the longest before MR&R activities are required. This was followed by Product A and then Product B. However, the difference between Product C and Product A was not statistically significant. Life cycle cost analysis showed that using a fast track partial depth high quality repair product was more cost effective than other types of repair.
