Recycling portland cement concrete has gained momentum as an alternative to resurfacing aging highway and airfield pavements. Recycling cuts down rawmaterial requirements, reduces the need to haul concrete across long distances and solves the problem of didposing of large amounts of pavement in an environmentally acceptable manner. Additional savings come from the decreased amount of energy required to haul, mix and place the recycled portland cement concrete. Recycling methods, equipment and applications are presented.
