Abstract

The invention relates to a stabilizer or recycler which has a rotor housing 8, in which a milling/mixing rotor 9 is arranged, and a unit 13 for discharging binder for soil or base material stabilization. In the civil engineering machine according to the invention, at least part of the supply container 14 for the binder, and in particular the part thereof which is of larger volume, is arranged to the rear of the milling/mixing rotor 9 in the direction of working. The center of gravity A of the supply container 14 is preferably arranged to the rear of the axis of rotation 10 of the milling/mixing rotor 9 in the direction of working. This special way in which the supply container is arranged gives an optimum weight distribution. Whereas the supply container 14, which is relatively heavy when filled with binder, is situated mainly to the rear of the milling/mixing rotor 9, the drive unit 12 of the civil engineering machine can be arranged ahead of the milling/mixing rotor. With the supply container and drive unit arranged in this way between the front and rear wheels 3, 4, the center of gravity of the civil engineering machine is situated in the region of the milling/mixing rotor 9, which is something that is aimed for in practice.
