Abstract:
In 2004, the Ministry of Transportation Ontario conducted a trial project to evaluate three precast concrete slab repair construction techniques for concrete pavements: the Michigan Method, the Fort Miller Super-Slab® Intermittent Method, and the Fort Miller Super-Slab® Continuous Method. The methods differed in how the base was prepared and how the precast slab was installed and dowelled to the adjacent concrete. Details of the repair installation are presented along with the results of nondestructive testing to determine load transfer efficiency across the joints.
