Challenge
Home to Air Force, Army and Navy air units, 16,000 people and one of the largest collections of historic military aircraft in the west, Travis Air Force Base handles more cargo and passenger traffic than any other military air terminal in the U.S.
CSI was selected to repair/replace two sections of an aircraft parking area known as 300 Ramp, originally installed in the late 1940s. One of the challenges facing the CSI team was the fact the area was immediately adjacent very active runways, taxiways and aircraft parking for the 60th Air Mobility Wing, the largest in the Air Force and comprised of a fleet of large transport and refueling craft. Another hurdle surfaced when it was discovered that areas originally designated for lay down and batching were unavailable. CSI quickly mobilized two significantly smaller areas and work was completed in a timely manner.
Because the airfield has been in active service since WW II with myriad changes over the years, the subsurface condition was unknown. Facilities added had few details about what lay beneath them. CSI successfully excavated in and around them without incident.
To lay the more than 4,200 cubic yards of drainage layer material – which completely covers the area under 12,100 cubic yards of new Portland cement concrete paving – CSI incorporated a newly acquired Gomaco RTP 500 placer/paver.
Despite the many challenges, CSI completed the project in less time than originally estimated, making the USAF a very satisfied customer.
