Abstract:

Natural highway aggregate is a finite resource that with continued use in construction

activities but some good quality aggregates used in existing concrete structures may be

re-used to replace with the natural aggregate. Due to the repair or replacement of aging

infrastructure, the increasing quantity of construction demolition waste generated, such

as concrete aggregates, cannot be wasted in landfills. Using recycled concrete

aggregate to replace with the natural graded aggregate base (GAB) or as Foamed

Asphalt in highway construction can contribute to a reduction in of greenhouse gas

emission and energy consumption but other environmental concerns need to be

addressed.

Therefore, the Maryland State Highway Administration (SHA) initiated a study to

evaluate the environmental sustainability of the use of recycled concrete aggregate

(RCA) as base material in for pavement construction.
