Recycling Concrete Pavements - ACPA Wiki

2018-9-4  One major incentive for concrete pavement recycling is economics. Aggregate costs (for fill, foundation and surface layers) constitute one of the greatest costs of highway construction, comprising between 20 and 30 percent of the cost of materials and sup­plies (Halm 1980). Concrete pavement recycling saves much of these costs.
