Evaluating Functional and Structural Condition Based Maintenances of Airfield Pavements
Abstract: This study evaluates
airfield pavements’ functional- and structural-condition to determine the most
economical maintenance method. As a part of the analysis, Pavement Condition
Index (PCI) for several runways, taxiways, and aprons has been determined by
MicroPAVER. Structural evaluation of airport pavements has been performed by
Falling Weight Deflectometer (FWD) test. Evaluation of Layer Moduli and Overlay
Design (ELMOD) also determines the required overlay thickness based on the
E-values, i.e. FWD data analysis. Damage analysis determines the time of
repeated overlay application. In addition, functional parameters have been
included to determine the time of functional maintenance. Maintenance and
rehabilitation alternatives have been selected to develop different program
strategies. Life Cycle Cost Analysis (LCCA) has been performed to determine the
maintenance cost. Structural condition based maintenance cost is compared to
functional condition based maintenance cost. Comparison shows that structural
condition based approach yields cheaper maintenance strategies than functional
condition based maintenance approach.
