To answer the economic constraints and environmental of the stabilization of ground or in situ bituminous mix recycling, BOMAG developed very powerful materials declined in Stabilisateur version or Recycler. Stabilization is addressed on the ground rich in silts which are consolidated by the addition of a bituminous binder, hydraulic or chemical, then intended to become base courses or underlayers. This process of stabilization soil also confers a very good resistor with freezing to him. The reclyclage is intended for the rebuilding of roadway per spraying of the layers of bitumen in place which are mixed with binder before being redeposited in only one and even operation.
