ECCC GE (Construction) STUDY GUIDE
SUMMARY LATEST GUIDE.
Four types of airfield pavement system surface structures
-Semi prepared airfield (unsurfaced, in-place soils or improved subgrade or
surfaced, membrane surfaced, and mat-surfaced).
-Semi prepared airfield (aggregate-surfaced layered structure over
compacted subgrade).
-Surfaced airfield (flexible pavement or bituminous pavement).
Surfaced airfield (rigid pavement
Airfield: Membranes and Matting
· expedient ways to get more passes on soil that has a CBR of at least 5
· Heliport Categories: Initial
-might begin with an insertion of Engineers to clear (LZs) for individual aircraft
or LZs of opportunity.
Usage:
-Individual Aircraft
-LZ of opportunity
LZ expanded into Semi-prepared and Surfaced as require
· Heliport Categories: Initial
-Unsurfaced
-Located anywhere in T/O, mostly in areas that sustain close combat
-Little or no construction effort
-May not meet desired safety criteria
-Hazardous, inefficient and limited to good weather and visibility
-No estimated service life
· Heliport Categories: Assault Heliport
,-Service Life is 1-4 weeks
-Normally Semi-Prepared/Unsurfaced
-Designed for
-Observation aircraft
-Utility Aircraft
-Attack Aircraft
Area of Operations Heliport
-Service life is 1-6 months
-Semi-Prepared/Unsurfaced
-Variety of matting/membranes
-Designed for
-Observation aircraft
-Utility aircraft
-Attack aircraft
-Cargo aircraft
-Permit full efficiency of operations
-Greater safety than shaping area heliports
-Operations are practical under most weather conditions
Heliports
o Helipads
o Heliports with taxi hover lanes
o Heliports with runways
o Mixed Battalion heliports
· Airfield Damage Repair (ADR):
o Process: Gain Security, Assess Site, Clear Site, Mark Site, Prepare Site,
Repair Site using one of the techniques
Airfield Damage Repair: Debris Backfill Crater
-Used when debris is plentiful and suitable for filling crater.
-Fill crater with debris up to 18 inches below the surface.
-Fill remaining portion of the crater with crushed stone.
, Airfield Damage Repair: Choke Ballast Over Debris
-Used when debris is suitable for fill, but limited.
-Fill the crater with useable debris.
-Fill the remaining area with ballast rock 18 inches below the surface.
-Fill the remaining portion of the crater with crushed stone.
Airfield Damage Repair: Choke Ballast
-Used when water is standing in the crater or if subsurface material is
unsuitable for filling the crater
-Fill the crater with ballast rock up to 18 inches below the pavement surface
Fill the remaining portion of the crater with crushed stone
Airfield Damage Repair: Crushed Stone Repair Procedures
Clear the debris from around the crater at least 6 meters (20 feet) in all
directions
-ID and remove all upheaval
-Clear at least 20 feet outside the lip of the crater.
-Move the debris at least 30 feet off the MOS, and stockpile it no higher than
3 feet to prevent FOD
-Once edges of the crater are visible, measurements should be taken to
estimate the amount of fill material required and how many FRP panels will
be required to cover the repair.
Airfield Damage Repair: Sand Grid Repair
Airfield Damage Repair: Crushed Stone Repair Procedures Cont.
-Fill and compact the crater with crushed stone material, placing it in lifts
approximately 6 to 7 inches thick.
-For C-17 operations, limit the aggregate size to a maximum of 1 inch in the
top 6 inches of the crushed stone repair.
-Overfill the crater by approximately 3 inches above the original pavement
surface height.
-Compact each lift of crushed stone.
-Four passes of a single drum vibratory roller
-Two passes with a 10-ton vibratory roller.
