Recycling Saves Money and Natural Resources. Fulldepth reclamation uses the materials from the deteriorated asphalt pavement, and, with the addition of cement, creates a new stabilized base. A surface consisting of a thin bituminous chip seal, hotmix asphalt, or concrete completes the road.
Highgrade recycling of EOL concrete liberates the old cement paste from the concrete which can then be recycled into new cement with lower CO 2 emissions. EndofLife concrete with steel rebars The aim of the Delft research is to create a highgrade recycling process for EOL concrete that is economically competitive with the RBA route but environmentally superior and more sustainable.

Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road term refers to the center layer of the roadbed. A crosssection of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally
Portland cement concrete recycling involves reclaiming existing portland cement concrete pavements and structures by crushing them to produce construction aggregate for reuse. Table lists the advantages and disadvantages of portland cement concrete recycling. The construction aggregate can be used for portland cement concrete pavements

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called
