Full Depth Reclamation with Cement along Rt. 2A in Reed Plantation

Due to the rising cost of virgin aggregate and asphalt products the Maine Department of Transportation (MaineDOT) utilizes a number of reconstruction and rehabilitation processes to cost effectively maintain Maine's highway system. One rehabilitation process in particular is full-depth reclamation (FDR) with cement. This process rebuilds deteriorated roadways by recycling the existing Hot Mix Asphalt (HMA). The old HMA and a portion of base material are pulverized in-place, mixed with cement and water, then shaped and compacted to produce a strong and durable stabilized base material that is sealed with a HMA surface. With the added strength of the stabilized base, thickness of the HMA surface can be reduced resulting in additional cost savings. By recycling the existing HMA materials, construction costs are reduced by 25% to 50% as compared to conventional construction methods.
