• 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.
