Abstract

· Evaluate conventional methods of slab removal and asphalt surface preparation for subsequent overlays of portland cement concrete (PCC) in the “remove and replace” areas. · Evaluate existing asphaltic concrete surface under the “remove and patch” areas of rehabilitation areas and evaluate joint formation in the areas of patching. · Evaluate polypropylene fiber enhanced concrete at the three-inch depth to determine the cost/benefit of its inclusion. · Evaluate the performance of the rehabilitated ultra-thin whitetopping sections and the extended performance of the existing ultra-thin sections with and without patching. · Validate existing ultra-thin whitetopping design procedures of the Portland Cement Association (PCA) and American Concrete Pavement Association (ACPA) for application in Iowa.
