This was the first project in the region to use the cold-in-place recycling method of construction, saving the airport more than $150,000 in construction costs.
Taxiway, and Apron Rehabilitation, City of Fairmont, Minnesota
The Fairmont Municipal Airport required pavement rehabilitation evaluations of Runway 13/31, Parallel Taxiway A, connecting taxiways, and an aircraft apron. Initially, the city wanted to reconstruct all airfield pavements. However, due to funding constraints, cold in-place recycling (CIR) of Runway 13/31 was recommended. CIR entailed pulverizing the top four inches of existing bituminous and re-paving as a two-inch base lift. This was the first project in the region to use this method of construction, requiring an FAA modification to standards. Construction included extensive site grading, storm sewer installation, subbase and base course pavement, milling, and replacing the airfield lighting and signing on Runway 13/31. As a result, the Fairmont Municipal Airport saved $150,000 in construction costs by using this innovative method. They received the same renewed pavement section for their runway to last the next 20 years.
