18 3.1 Introduction Airports, especially commercial airports, can have vast networks of paved surfaces, as summarized in Figure 8. As previously discussed, the paved surfaces at these facilities are generally classified as either landside or airside, with landside referring to those areas outside of secured locations, and airside being those areas within secured areas where aircraft operate.

24 Guidance for Usage of permeable pavement at airports 3.3.1 Traffic Demands Traffic on airport pavement is divided into vehicular traffic and aircraft traffic. Aircraft traffic data need to conform to the FAA's design procedure in AC 150/5320-6F, Airport Pavement Design and Evaluation (FAA 2016)

permeable pavement applications 25 may provide adequate capacity for a rainfall event on a taxiway, but shoulder pavement may not provide sufficient capacity for a rainfall event on a large apron area. Wittman Airfield constructed a hybrid system in which the taxiway pavement was a conventional HMA (impervious)
