IMPACT OF OPEN-GRADED DRAINAGE LAYERS ON THE CONSTRUCTION OF CONCRETE PAVEMENTS IN ILLINOIS

The first portland cement concrete pavement test section constructed by the Illinois Department of Transportation, which included an open-graded drainage layer, was built in 1989. Since the construction of that project, over 30 centerline km (20 centerline mi) of concrete pavements have been built using an open-graded drainage layer. Although the benefits of using open-graded drainage layers to improve concrete pavement performance are widely accepted, the practical impact of the design details on the constructability of concrete pavements requires additional attention. Examples of problems encountered during the construction of concrete pavements with open-graded drainage layers include placing the open-graded drainage layer, anchoring dowel baskets to the open-graded drainage layer, obtaining a pavement with adequate ride characteristics, and using the open-graded drainage layer to support paving operations. From the experience acquired while constructing several pavements with open-graded drainage layers in Illinois, it is clear that concrete pavements with open-graded drainage layers can be constructed to meet today's high construction standards.
