This paper presents the results obtained from the laboratory investigation aimed at determining the possibility of making asphaltic mixes of acceptable quality for road surfacing, from raw tar sands (as they occur in nature). The tar sand samples consist mainly of fine sand, water, and bitumen. Five different types of asphaltic mixes were produced from tar sands and superheated aggregates. On the basis of Marshall and indirect tensile (Brazilian) tests carried out on the produced asphaltic mixes, the investigation revealed that raw tar sands are good material for the production of asphaltic mixes. The results of the investigation also suggest that for a given mix set, there may be correlation between maximum value of Marshall stability and maximum indirect tensile strength.
