The demonstrated durability, flexibility and structural capacity of hot-mix asphalt and PCC concrete makes it possible to provide economic, smooth, safe pavements for highways and airports for heavy traffic conditions and severe operating environments. A mega transportation project is considered to involve: greater than $100 million in construction costs; an alternative delivery method such as design-build; life cycle costing for technology evaluation; fast track construction; and total quality management. Recent involvement in mega projects - Dominican Republic Duarte Highway, Colombia Bogota El Dorado International Airport, Highway 407 ETR-Express Toll route north of Toronto, Nova Scotia Cobequid Pass Highway and New Brunswick Fredericton-Moncton Highway - is used to illustrate the advantageous application of asphalt and concrete technology, with emphasis on life-cycle costing and value engineering. The focus of the pavement technology described is on the practical concepts involved, and particularly the key role of the paving contractor in meeting the fast-track technical and quality requirements of mega paving projects.
