The UK Specification for Highways Works (MCHW 1) currently makes no specific provision for the use of Continuous Compaction Control (CCC) in the construction of earthworks for roads and highways. Such techniques can be used by the constructor but the provisions of the MCHW 1 take primacy leaving little incentive to do so. In this report the potential benefits of the use of CCC are outlined. These benefits include the provision of real time monitoring of compaction operations and of a permanent record of the process, the dentification of soft spots, and the determination of the stiffness or relative density of a compacted material subject to performance specification. It is concluded that there is no major technical obstacle to the introduction of CCC to road and highway earthworks in the UK. The potential introduction of CCC is described in the context of the UK Specification for Highway Works. |
