What actually are the possibilities of effecting savings by using the T-RRP method?
In principle, savings are effected in two ways: 1. The entire foundation of a road or yard (comprising the base and the sub-base or frost blanket) is eliminated; 2. At least 50% of the thickness of the surfacing can be dispensed, because on the optimal compacted T-RRP processed base a surfacing is immune from damage by water or frost, as the sub-grade (the underlying soil) is fully stabilized and immovable. The surfacing therefore does not have to perform a load-bearing structural function, but serves merely as a wearing course.
