FUNDAMENTAL PROPERTIES OF RECYCLED ASPHALT MIXES. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

Experience has shown hot mix recycling to provide a cost-effective rehabilitation option. To resolve some residual doubts about quality, recycled mixes have been evaluated in South Africa through a laboratory investigation and Heavy Vehicle Simulator testing. The laboratory study was carried out to determine the initial engineering properties of asphalt mixes composed of different proportions of reclaimed material, yet meeting the design criteria of conventional mixes. It was found that the proportion of reclaimed material had no effect on permanent deformation and fatigue resistance. This study took no account of either the durability characteristics of recycled mixes or the effect of recycling additives. These factors are currently being investigated. The Heavy Vehicle Simulator has been used to test recycled asphalt base layers. The results of this accelerated testing suggest that the field behaviour of recycled base mixes is comparable to that of conventional asphalt.
