Ebook: Compaction Technology: Proceedings of the conference organized by New Civil Engineer and held in London on 29 October 198

The Department of Transport's sixth edition of "Specification for highway works" is the most significant development in compaction technology over the past decade. It forms the basis of the government's expenditure on UK roads - annually worth about #1000 million to the construction industry. The specification incorporates major changes including an increase in layer thickness, the acceptance of vibratory rollers and adoption of a percentage refusal density performance specification.
