This report describes the development of guidelines for determination of maintenance and repair M and R needs of airfield pavements. The guidelines are based on the pavement condition index PCI and other condition indicators, including rate of deterioration, cause of deterioration, load carry capacity, skid resistancehydroplaning, surface roughness, and extent of previous M and R. The M and R methods were divided into three general categories routine, major, and overall. The mean pavement PCI was found to relate strongly to M and R needs represented by these three M and R categories. M and R zones for use in selecting the appropriate M and R category were established based on the mean pavement PCI. Other condition indicators are used to further aid in the selection of feasible M and R alternatives. Recommended M and R methods for the different distress types and severity levels were developed. Economic analysis procedures were developed for comparing M and R alternatives. The airfield pavement condition survey and rating procedures have been successfully field-tested. Performing the condition survey according to these procedures does not require expensive equipment only a measuring wheel and straightedge are required. The results can be used to rate pavement condition and to select M and R requirements for all pavement features of the airfield.
