Hot mix asphalt using C&D waste as coarse aggregates

Abstract

[Abstract] This article evaluates the possibility of designing hot asphalt mix road pavements using Construction and demolition waste as coarse recycled aggregates. The percentages of recycled aggregates used in the mixtures were: 0%, 20%, 40% and 60%. Cement and lime were used as fillers. The mixtures made with coarse recycled aggregates complied with the Marshall technical specifications for low volume roads. The mixtures also showed good resistance to permanent deformation evaluated by means of wheel tracking tests. Nevertheless, the mixtures made with RA may have insufficient durability due to their high susceptibility to water action which was evaluated using stripping tests.
