                      3.  Procedures for identifying alternative maintenance and reha-
                        bilitation strategies
                      4.  Mechanisms for predicting and evaluating the impact of pave-
                        ment maintenance and rehabilitation strategies and alternatives
                        on pavement condition, serviceability, and useful service life
                      5.  Procedures for estimating and comparing the costs of various
                        strategies and alternatives
                     6.  Techniques for identifying the optimal strategy or alternative
                        based upon relevant decision criteria
                    Essential to an effective PMS is the maintenance of a pavement
                 database which should include
                      1.  Information about the pavement structure, including when it
                        was originally constructed, the structural components, the
                        soil conditions, a history of subsequent maintenance and reha-
                        bilitation, and the cost of these actions.
                     2.  A record of the airport pavement traffic including the number
                        of aircraft operations by various types of aircraft using the
                        pavement over its life.
                     3.  The ability to regularly track pavement condition, including
                        measures of pavement distress and the causes of distress. A
                        pavement rating system should be developed based upon the
                        quantity, severity, and type of distress affecting the pavement
                        surface condition. This rating system measures pavement
                        surface performance and has implications for structural per-
                        formance. The periodic collection of condition-rating data is
                        essential to tracking pavement performance
                    As part of an effective PMS, the evaluation of airport pavements
                 should be a methodical process, which includes a thorough review of
                 construction data and usage history, routine site inspections, and
                 pavement sampling and testing. Types of sampling and testing pro-
                 cedures include: direct sampling, nondestructive testing (NDT),
                 ground penetrating radar, and infrared thermography.
