3E551 CDC Volume 4. Contingency
Responsibilities- Questions & Answers
When a repair patch, and the one immediately after need to be repair flush, how is that noted?
Correct Ans-FF.
Which team is responsible for comparing the crater repair with the repair quality criteria (RQC)
value? Correct Ans-Crater profile measurement (CPM) team.
Because the repair slope matches the runway slope, how are the crater profile measurement
(CPM) test lanes related to the runway centerline? Correct Ans-Parallel.
How many, and at what interval, are approach lighting marker cones placed off the minimum
operating strip (MOS)? Correct Ans-7 at 200 feet.
To assist the paint stripping team, centerline cones are offset how far to the left when placing
them along the minimum operating strip (MOS)? Correct Ans-2 feet.
Taxiway intersections with the minimum operating strip (MOS) are marked by three cones,
spaced three feet apart, in what type of formation? Correct Ans-Equilateral triangle.
How many edge markers are placed on either side of the threshold and departure ends of the
minimum operating strip (MOS)? Correct Ans-10.
, With the exception of immediately after the arresting system, edge markers should be placed at
what interval? Correct Ans-200 feet.
How far off the edge of the minimum operating strip (MOS) are distance-to-go (DTG) markers
placed? Correct Ans-25 feet.
When performing crater profile measurement (CPM) to measure upheaval, the person holding
the rod continues to take one pace toward the stanchion until the.... Correct Ans-Target
triangle on the rod IS NOT visible.
Before making the pavement, the person holding the rod will do what last step during crater
profile measurement (CPM)? Correct Ans-Take on additional step toward the stanchion.
To ensure that each blow to the dynamic cone penetrometer (DCP) anvil has the same force,
what action must take place with regards to the hammer? Correct Ans-Allow the hammer to
freefall.
During soil strength evaluation, the DCP recorder notes the number of blows every.... Correct
Ans-25mm.
After how many blows without penetrating deeper, should you remove the drive rod, change
locations, and restart the DCP test? Correct Ans-20.
What do we call the relationship between the number of DCP blows and its depth of penetration?
Correct Ans-DCP Index.
