Full-Depth Reclamation with Cement

摘要

Deteriorating roads are a constant problem for cities and counties. Today engineers and public works officials are turning to a process called full-depth reclamation (FDR) with cement to economically and sus-tainably repair and replace damaged roads. FDR with cement rebuilds worn out asphalt pavements by recycling the existing roadway. There is no need to haul in aggregate or haul out old material for disposal. Truck traffic is reduced, and there is little or no waste. The recycled base is stronger, more uniform, and more moisture resistant than the original base, resulting in a long, low-maintenance life. And most important to the tight budget of a department of transportation, recycling costs are normally at least 30 to 60 percent less than the removal and replacement of the old pavement.
