4 There are 382 primary airports and 2,950 non-primary airports in the United States' NPIAS, including 530 Part 139 airports. Taken together it is estimated that there are approximately 460 million square yards of paved airfield surfaces at NPIAS airports.

While the FAA does not appear to have a formal definition of "good," "fair," and "poor," one approach it uses to apply descriptive terms to PCI ranges is shown in Figure 3 (see the General Ratings column)

Importance of Pavement Condition Data in Managing Pavements 9 distresses indicative of a structural deficiency, but still be a poor candidate for pavement preservation because of insufficient long-term structural capacity. This can be evaluated by determining the structural capacity of the pavement with FWD testing.

10 Guidelines for Collecting, Applying, and Maintaining Pavement Condition Data at Airports Current conditions are frequently reported in either tabular or graphical form to communicate the findings from a pavement condition survey. Table 2 is a tabular presentation of PCI data from a network-level survey, while Figure 4 shows conditions plotted on a map of an airport's pavement facilities.

12 Guidelines for Collecting, Applying, and Maintaining Pavement Condition Data at Airports Prepare Multi-Year CIPs and Communicate Needs When pavement condition data are generated, analyzed, and stored as part of a PMP, the information needed to develop multi-year CIPs is available. In contrast with a maintenance or preservation plan, which is typically linked to actions required in a given year or at most a year away, a CIP is a planning tool in which the projections of future pavement conditions are used to indicate when a capital project such as a structural overlay or reconstruction will be needed.

Importance of Pavement Condition Data in Managing Pavements 13 A CIP may start with a table of capital projects that are triggered in future years and the associated costs, as shown in Table 3. With PCI-based models, a wide range of alternate scenarios can be analyzed, such as the following: • No budget: predicted conditions in 5 years if capital projects are not constructed.
