Recent innovative developments in concrete pavement design methodology, material specification, construction techniques, and pavement drainage systems prompted Ontario's Ministry of Transportation and Communications to consider alternative rigid pavement designs. In order to evaluate the relative performance of several concrete pavement designs, a 15.5 km (9.7 mi) long experimental rigid pavement was constructed in 1982 incorporating four different pavement designs, three shoulder designs and two types of surface textures. A summary of the design and construction details, plus the initial performance results of an ongoing monitoring program are documented in this paper. Early performance observations indicate superior performance of the freedraining basematerials. In addition, some anomalous behaviour based on pavement cracking and roughness suggest additional areas of process control are warranted. Continuing performance verification of preliminary conclusions indicate the new designs have resulted in a significant saving in construction materials and costs plus increased durability and oerformance with a corresponding reduction in future maintenance costs.
