21. A process for preparing a castable hot mixture of
bituminous concrete, comprising the steps of:
introducing into a mixture of hot bituminous concrete a
multiplicity of steel wire pieces adapted for strengthening

solidification;
and
mixing said steel wire pieces in said mixture of hot
bituminous concrete until said steel wire pieces are equally
distributed in said mixture of hot bituminous concrete,
wherein
said steel wire pieces are introduced in the form of

said bundles by a binding substance which is adapted to
disintegrate by water when mixed into a wet cementitious

hot bituminous concrete mixture, and wherein said steel
bundles disintegrate during mixing of said mixture of hot
bituminous concrete.
