AAAE ACE Operations Module 2 1.What are the two major categories of pavement ANS Flexible and rigid 2.What are some types of flexible pavement ANS Grass, dirt, gravel and asphalt 3.Why are paved surfaces necessary at airports ANS To support the critical loads imposed on them; to produce a smooth, skid-resistant and safe-riding surface 4.Airport surfaces are distinguished by operational control and FAA design standards into what two areas ANS Movement and non- movement 5.What constitutes the movement area on an airport ANS Runways and taxiways. At ATCT controlled airports, the surfaces under ATC control.These areas must meet Part 139 design restrictions. 1 / 3

6.What constitutes the non-movement area of an airport ANS Taxiways and aprons not under ATCT control 7.How are movement and non-movement areas determined at an airport with an ATCT ANS By Letter of Agreement (LOA) between the airport and the ATCT.

8.What is the benefit of using a rigid pavement such as Portland Cement Concrete ANS 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.

9.What are two major elements that make pavements deteriorate ANS weather- ing and aircraft loads 10.For bearing strengths of 12,500lbs or greater, what method is used to ex- press the effect of an individual aircraft on different pavements ANS Comparing ACN to PCN (Aircraft Classification Number-Pavement Classification Number) 2 / 3

3 / 10

11.What does the Pavement Classification Number (PCN) represent to the operator/pilot ANS PCN is the maximum pavement bearing strength for unrestricted aircraft operations.

12.What is the Load Classification Number (LCN) used to describe ANS Pave- ment bearing strengths less than 12,500lbs 13.What are the five major categories of pavement distress ANS cracking, joint seal damage, disintegration, distortion, loss of skid resistance 14.Edges of abutting pavement or pavement and other areas must be no more than how many inches in elevation difference ANS 3 inches 15.What are the maximum dimensions of a hole that are allowed by Part 139 ANS Any hole with a diameter greater than 5 inches and either 3 inches deep or a slope of greater than 45 degrees
