Bitumen

Bituminous stabilisation is used to introduce cohesion non plastic material or to make cohesive material less sensitive to less of stability with increased moisture.

The process is very successful with granular material in bases. The resultant pavement performs as a low modulus asphalt which is used often as a substitute in the layers below wearing course.

Bituminous stabilisation in recent times has used either foamed hot bitumen or bitumen emulsions to introduce the binder into the mix.
