Using the full-depth reclamation process saved the City of Hutchinson a substantial amount of money.
Runway 15/33, Taxiway A, and the apron pavements were in dire need of reconstruction due to severe longitudinal and transverse cracking, raveling, and transverse joint depressions. Fully reconstructing all pavements in one year was not feasible because of limited federal funding.
Bolton & Menk designed and constructed a full-depth reclamation (FDR) project to improve the airport's pavement condition. FDR is the process of pulverizing the existing bituminous and blending with the underlying aggregate base to provide a recycled bituminous base course. FDR recycles existing materials on-site while providing a comparable product to virgin aggregate base at a substantially lower price.
Using the FDR process allowed the city to reconstruct the runway, taxiway, and apron within the federal funding amount available.
