Abstract: The invention relates to an elastic street pavement mass comprising aggregate bound by a binder and, when needed, coloring agents and other additives, and which is particularly suitable for preparing pavements having the shade of the aggregate or being toned. The efforts made so far to replace bitumen, which is hard to dye, by a colorless binder, have resulted in the use of expensive and brittle binders. However, an economical, strong and dyeable pavement mass has now been discovered, the binder of which consists of tall oil resin, wood resin, turpentine resin, their derivatives or a mixture formed by these agents, and of a process oil softening the above resins, comprising additionally rubber and plastic as auxiliary agents. The products have a better stability and at least as high an abrasion resistance to studded tires as a conventional bitumenous pavement mass.
