• Abstract:
  Maine has hundreds of miles of roadway originally constructed with Portland Cement Concrete that now ; are covered with Hot Mix Asphalt overlays. In 2001 the Maine Department of Transportation utilized an ; experimental construction technique on one of these PCC highways. The project was a rehabilitation and ; resurfacing project located in Winslow. In an effort to provide a more durable roadway, recycled ; materials were used in an innovative way. The project utilized Portland cement, together with reclaimed ; asphalt pavement (RAP) milled from the highway, together with new aggregate to reinforce and stabilize ; road shoulders adjacent to the existing old concrete slabs. The goal was to strengthen the shoulder ; adjacent to the existing concrete slabs and widen the travel lanes to prevent future premature deterioration ; in the shoulder. Figure 1 shows the project location. In this report the mixture of pavement grindings ; (RAP) and Portland cement material will be referred to as RAP/PC blend
