Tigerbrain Engineering, Inc. provided airfield pavement SME Title I services for a CPFF project supporting the full depth repair of Runway 13-31 at Ascension Auxiliary Airfield. We deployed a site evaluation team led by Dr. John R. Anderson, PE, and Mr. Jim Lafrenz, PE, and our airlift-ready laboratory to identify critical runway reconstruction features.
Tigerbrain’s pavement and subsurface geotechnical investigation identified numerous challenges and solutions to reconstruct on volcanic ash that degrades under construction equipment. Tigerbrain investigated multiple global aggregate sources and developed the quarry and on-site crushing requirements to produce the 400,000 tons of material that would meet UFGS criteria after handling seven times.
Tigerbrain developed the concrete, asphalt, and aggregate base mix designs that could be achieved after receiving the trans-Atlantic aggregate shipments.
Tigerbrain was on-site to prepare for and pave the asphalt test section, and then provided on-site personnel throughout paving.
