Table 5-2 gives the cover requirements for culvert under airfields. This table is composed of a series of charts,
based on aircraft load and gear configurations. Each of these charts is headed by a weight and gear type. These
charts are good for 5,000 pounds more than listed (such as the chart headed "60,000-lb Single Wheel" is good for
single wheel loadings up to, and including 65,000 pounds).
Table 5-2. Minimum cover requirements, in feet, for airfields (CMP)
Each chart is subdivided into columns headed by culvert diameters (in inches) and rows based on the gauge of the
metal. Linear interpolation can be used for the incremental diameters not listed. The body of the chart gives the
cover required, in feet, for the diameter and gauge of pipe concerned.
