Port of Portland, Airside Network Evaluation

GRI completed a network-level pavement evaluation for five areas around the Portland International Airport (PDX) to evaluate the remaining life of the pavement and assist the Port with its pavement-management project selection and budget forecasting. The locations included the PDX Maintenance Facility, portions of Perimeter Road, Taxiway B, Terminal Gates, and the Taxiway T Apron.

Our investigation consisted of Falling Weight Deflectometer (FWD) testing and pavement coring. The airfield pavement analysis was completed in general accordance with FAA AC 150/5320-6 and 150/5370-11. The perimeter road and maintenance facility pavement analysis was accomplished in accordance with the 1993 American Association of State Highway and Transportation Officials (AASHTO) Guide for Design of Pavement Structures (AASHTO Guide). The structural pavement analysis was based on GRI’s FWD deflection test results and the pavement thickness information provided from the Port’s pavement-management system records supplemented by our core explorations and calibrated pavement-thickness calculations. The remaining life analyses was derived from a correlation between pavement thickness and pavement stiffness at our core locations.
