At ATCT controlled airports, the surfaces under ATC control. These areas must meet Part 139 design restrictions.

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) 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 Edges of abutting pavement or pavement and [Show More]
