CEMENT STABILISED GRAVEL

CEMENTSTABILISERAT GRUS. Owing to the rise in bitumen prices, the use of cement stabilised gravel is becoming an interesting alternative to bitumen stabilised gravel. CG has high flexural strength and therefore wheeltracking is reduced. CG is made at ready mixed concrete plants using well graded aggregate, and standard or other cement.
