The PDX Taxiway K project included massive taxiway reconstruction at the Portland International Airport due to cracking in the taxiway. This project required working around tight security and extensive Federal Aviation Administration (FAA) requirements to reconstruct twelve different sections of taxiway on a fast-paced 5 and a half month schedule. In a span of 160 working days and 25,000 man hours, crews ground, mixed, and placed 18,000 tons of sub-base, paved 12,900 cubic yards of concrete asphalt and 38,800 tons of hot mix asphalt, laid 3,500 feet of 48” storm pipe and installed 4,700 feet of utilities. Despite very stringent specs, we developed a value engineering idea to create a sub-base for the pavement by mixing the project’s crushed concrete with the site’s native material to reduce time, resources, and cost. After testing, the new mixture was approved for the job and resulted in a $150,000 cost savings for the owner.
