[origin: EP0319702A2] The surfacing for base courses, in particular according to ZTVT-StB 86, consists of nitrogen and/or synthetic minerals and a binder mixture of bitumen and hydraulic binder, where the content of bitumen and that of hydraulic binder are each 1.0 to 3.0% by weight, based on the base course mixture, the content of both together is at least 3% by weight and the total water content corresponds approximately to the water content which permits the greatest compactness, measured according to Proctor (DIN 18,127). The bitumen is added in the form of an anionic aqueous emulsion. The surfacing is economical, stable and simple to prepare and meets the highest requirements.
