If I have heavy traffic how do I strengthen the sub-base?

A punched layer of Dense Bitumen Macadam ( DBM ) can be used to strengthen the pavement sub-base. Alternatively Hydraulically Bound Coarse Graded aggregate can also be used. Guidance on this can be found in BS 7533 Part 13 or contact Tobermore for details.
