What are the two major categories of pavement? Flexible and rigid What are some types of flexible pavement? Grass, dirt, gravel and asphalt Why are paved surfaces necessary at airports? To support the critical loads imposed on them; to produce a smooth, skid-resistant and safe-riding surface What is the benefit of using a rigid pavement such as Portland Cement Concrete? It is about half the lifetime cost of asphalt, with a service life of 30+ years versus 5-15 years for asphalt. Concrete is more expensive up front though, so asphalt is common at low revenue airports such as GA. What are two major elements that make pavements deteriorate? weathering and aircraft loads For bearing strengths of 12,500lbs or greater, what method is used to express the effect of an individual aircraft on different pavements? Comparing ACN to PCN (Aircraft Classification Number-Pavement Classification Number) ACN less than or equal to PCN What does the Pavement Classification Number (PCN) represent to the operator/pilot? PCN is the maximum pavement bearing strength for unrestricted aircraft operations. What is the Load Classification Number (LCN) used to describe? Pavement bearing strengths less than 12,500lbs What are the five major categories of pavement distress? cracking, joint seal damage, disintegration, distortion, loss of skid resistance How far are landing distances increased on wet pavement? By 15 percent or more Where are wind cones located? at least one on the airport, lighted if night carrier operations occur; additional cones placed so that every takeoff and landing runway has a cone visible to pilots
