Partial and/or Full depth recycling or reclamation, is a process that rebuilds worn out asphalt pavements by recycling the existing roadway. Old asphalt and base materials are pulverized using a specialized machine called a reclaimer. On top of the pulverized material, water is added to reach the optimal moisture content for compaction and then a variety of materials, such as dry cement, lime, fly ash, or asphalt emulsion, are incorporated for stabilization.
A reclaimer is used again to mix all the materials. After shaping and grading, the new base is compacted to produce a strong, durable base for either an asphalt or concrete surface. Since this method recycles the materials on site, there is no need to haul in aggregate or haul out old material for disposal.
