As part of a proactive approach to network-level pavement management, Hartsfield Jackson Atlanta International Airport includes Roughness Assessment of each of the four runways. The runway's longitudinal profiles are measured on a biannual basis using the Auto Rod and LevelTM. The profiles are then analyzed for pavement roughness using several computerized techniques such as takeoff and landing simulations, VSweepTM, and straightedge simulations. These analyses are quantified into a Pavement Smoothness Index (PSI) for each 500-foot section of pavement. The early detection of roughness allows airport managers to make better, more informed and timely decisions regarding maintenance. Data measured and analyzed in the 2004 program revealed areas of moderate roughness on Runway 8L-26R, originally constructed in 1984 and primarily used as a landing runway. Repairs could be important due the affect of roughness on potential safety situations such as an aborted takeoff. Also, since roughness has a tendency to increase over time, repairs done early will decrease the likelihood of a negative impact on aircraft operations. Runway 8L-26R has received only minor maintenance repairs such as patching, joint resealing, crack sealing and spall repairs during its 21 years of performance. Because of Atlanta's proactive strategy, the moderate rough areas found on Runway 8L-26R are scheduled to be corrected using diamond grinding techniques to remove bumps and lessen the effects of dips.
