This paper was presented at the `Value-Added Pavement Design and Performance' session. This paper presents the pavement structure selection process for the new Runway 15R-33L at Pearson International Airport in Toronto. The runway is 2740 m long and 60 m wide with capability of accomodating most of today's heavy jet aircraft. Traditionally, Portland cement concrete has been used for Pearson Airport runway pavements. During the preliminary design stage, a study was carried out to evaluate various pavement types and to select the optimum design for the new Runway 15R-33L. Portland cement concrete, roller compacted concrete, hot mix asphalt concrete, composite structures and split strength design were the pavement types evaluated. The design methods used for the structural analysis was Public Works, Air Transportation's current pavement design practice. The pavement selection procedures took into account the initial construction cost, maintenance cost, restoration, operational disruptions to airport traffic during construction (for restoration) and life cycle costing. Hot mix asphalt concrete was selected. The runway is under construction and scheduled for completion in 1997. (A)
