INFRASENSE INC. GPR rig setup for 23 South Carolina airfields. Clockwise from lower left, 1 GHz horn antenna; rooftop GPS receiver (to right of strobe); electronic distance-measuring device to right of rear wheel; and [red] 400 MHz ground coupled antenna GPR, FWD Analyze Airfield Pavements in South Carolina By K. Maser, A. Carmichael and W. Weiss T he South Carolina Aeronautics Commission recently completed a project to evaluate the condition and capacity of pavements at 23 airfields in South Carolina. The project, carried out by Applied Research Associates (ARA) with support from Infrasense, Inc., sought to evaluate both the weight bearing strength and the Pavement Classification Number (PCN) on all runways, taxiways, aprons, and ramps for each of the airfields investigated aircraft. PCNs are used in conjunction with aircraft classification numbers (ACN) 30 to identify the strength of airport pavement facilities. This information is critical for airport operations in determining the type of aircraft that can land, and prescribing taxiing patterns. Overloading of airport pavements can significantly reduce their life and performance, and leads to relatively costly rehabilitation maintenance efforts. The PCN is expressed as a five character code which incorporates load capacity, pavement type, substructure strength, maximum tire pressure capacity, and method of evaluation.
