CGS Consolidamenti uses cold recycled technology with foamed bitumen to stabilise sub-base layers and for cold recycling processes. This particular treatment type is not suitable for absorbing shear and tensile stress and therefore not suitable for surface layers of the pavement (binder and/or mat type). It is suitable for replacing hot bases and layers of cement mixtures in the road foundation, improving mechanical performance and extending the life of the whole road construction.
