ABSTRACT The large underground tank consists of a metal shell, a static facing in reinforced or unreinforced concrete and filling material packed in the hollow space between the two above-mentioned surfaces. The filling consists of blown bitumen having plasticity properties which provide a stress resisting interaction between the tank shell and its static facing, thus greatly improving the stability of the tank structure.
