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.
