CRACK AND SEAT PCC PAVEMENT PRIOR TO ACC RESURFACING - US 59 SHELBY COUNTY. FINAL REPORT

Asphalt concrete resurfacing is the most commonly utilized rehabilitation practice used by the Iowa Department of Transportation. The major problem with asphalt concrete resurfacing is the reflective cracking from underlying cracks and joints in the portland cement concrete (PCC) pavement. Cracking and seating the PCC prior to an asphalt overlay was the construction method evaluated in this project. There was cracking and seating on portions of the project and portions were overlaid without this process. There were also different overlay thicknesses used. Comparisons of crack and seating to the normal overlay method and the different depths are compared in this report. Cracking and seating results in some structural loss, but does reduce the problem of reflection cracking.
