Question:
What are some types of flexible pavement?
Answer:
Grass, dirt, gravel and asphalt
Question:
Why are paved surfaces necessary at airports?
Answer:
To support the critical loads imposed on them; to produce a smooth, skid-resistant and safe-riding
surface
Question:
Airport surfaces are distinguished by operational control and FAA design standards into what two
areas?
Answer:
Movement and non-movement
Question:
What constitutes the movement area on an airport?
Answer:
Runways and taxiways. At ATCT controlled airports, the surfaces under ATC control. These areas
must meet Part 139 design restrictions.

Question:
How are movement and non-movement areas determined at an airport with an ATCT?
Answer:
By Letter of Agreement (LOA) between the airport and the ATCT.

Answer:
weathering and aircraft loads
Question:
For bearing strengths of 12,500lbs or greater, what method is used to express the effect of an

Answer:
Comparing ACN to PCN (Aircraft Classification Number- Pavement Classification Number)
Question:
What does the Pavement Classification Number (PCN) represent to the operator/pilot?
, Answer:
PCN is the maximum pavement bearing strength for unrestricted aircraft operations.
Question:
What is the Load Classification Number (LCN) used to describe?
Answer:
Pavement bearing strengths less than 12,500lbs
Question:
What are the five major categories of pavement distress?
Answer:
cracking, joint seal damage, disintegration, distortion, loss of skid resistance
Question:
Edges of abutting pavement or pavement and other areas must be no more than how many inches in

Question:
What are the maximum dimensions of a hole that are allowed by Part 139?
