Abstract

The work discusses the incorporation of recycled aggregates (RA) in road pavement materials considering asphaltic concrete mixes and base or sub-base layers. Replacement of coarse RA instead of coarse natural aggregate (NA) in asphalt mixtures was investigated. It was found that the use of coarse RA in asphalt concrete mixes were complied with the Marshall technical specifications, but it may have insufficient durability due to their high susceptibility to water action which was evaluated using the retained stability test. These asphalt mixtures may be used in the underneath layers of road pavements such as base course layers, but it should be avoided in wearing or water proofing in the upper layers of pavements. On the other hand, the analysis of the RA materials required for using it as base or sub-base in roads were successfully in the range of specification limits. These materials could be incorporated and declared in the Egyptian specifications as an aggregate for roads.
