- Flexible and rigid
What are some types of flexible pavement? - CORRECT ANSWER -
Grass, dirt, gravel and asphalt
Why are paved surfaces necessary at airports? - CORRECT ANSWER -
To support the critical loads imposed on them; to produce a smooth,

,What constitutes the movement area on an airport? - CORRECT
ANSWER - Runways and taxiways. At ATCT controlled airports, the
surfaces under ATC control. These areas must meet Part 139 design
restrictions.
What constitutes the non-movement area of an airport? - CORRECT
ANSWER - Taxiways and aprons not under ATCT control
How are movement and non-movement areas determined at an
airport with an ATCT? - CORRECT ANSWER - By Letter of Agreement

What is the benefit of using a rigid pavement such as Portland Cement
Concrete? - CORRECT ANSWER - It is about half the lifetime cost of

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? -
CORRECT ANSWER - 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? -
CORRECT ANSWER - Comparing ACN to PCN (Aircraft Classification
Number-Pavement Classification Number)
What does the Pavement Classification Number (PCN) represent to
the operator/pilot? - CORRECT ANSWER - PCN is the maximum
pavement bearing strength for unrestricted aircraft operations.
What is the Load Classification Number (LCN) used to describe? -
CORRECT ANSWER - Pavement bearing strengths less than 12,500lbs
What are the five major categories of pavement distress? - CORRECT
ANSWER - cracking, joint seal damage, disintegration, distortion, loss
of skid resistance
