There is, at this time, considerable emphasis on the use of recycled materials for highway Construction. Many States have initiated legislation to direct their highway agencies to investigate the possibility of recycling different waste byproducts into highway pavements and/or appurtenances.
dwindling landfill space, reduces disposal costs, and may reduce overall projects costs. The primary reason for considering recycling, however, is the high quality of
landfill space is scarce, dumping c o n c r ete is difficult and costly. The cost of recycling concrete pave-ments only includes the cost of c r ushing. Costs for aggregate haul-ing and concrete disposal are elim Recycling concrete pave-ment yields 45% to 80% usable coarse aggregate. Yield will vary
Recycling concrete from demolition project can result in considerable savings since it saves the costs of transporting concrete to the landfill (as much as $ .25 per ton/mile), and eliminates the cost of disposal (as high as $100 per ton).
