ENERGY SAVING FROM ASPHALT RECYCLING

Hot recycling of asphalt materials offers potential benefits such as cost reduction, energy savings and conservation of natural resources. Hot recycling of asphalt concrete pavement materials involves removing a pavement surface, full or partial depth, and reducing the material to an appropriate size. The salvaged aggregate is reprocessed through a hot mix plant and the resultant mix laid as a base, binder or surface course. To develop a good mix design adequate samples must be obtained and tested to indicate condition of salvaged asphaltic concrete and mix deficiencies. Other tests should determine additives necessary to bring the properties of the recycled material to be equivalent to a conventional mix. The article reviews the heating and mixing equipment available and the performance of resultant mixes. Test results have indicated that the ageing characteristics of asphalt binder may be enhanced through the recycling process. (TRRL)
