Abstract
The present paper discusses the environmental impact of various materials used in road constructions and the degree to which application methods are of importance in this context. Some twenty materials were selected for study after an inventory had been made of both commonly used road construction materials (primary materials) and waste materials considered to be suitable for such applications (secondary materials). Each material was sampled in duplicate and its composition and leaching characteristics determined using standard tests. It was found that generally primary materials pose less of a threat to the environment than secondary materials, regardless of whether the comparison is made on the basis of composition or leaching behaviour. A number of primary and secondary materials have been selected for fürther evaluation under practical conditions.
