Road scheme in the Pennines, arguing with the RE about acceptable compaction limits in wet weather. Where's the definitive reference — SHW, MCHW, or is it down to the RE's discretion?
SHW Series 600 is the reference — specifically the Moisture Condition Value limits in the contract-specific Appendix 6/1. For Class 1A general granular fill you're typically halting when the MCV falls outside the stated band, but the RE holds discretion under SHW 612 for compaction trials. The practical answer: agree an end-product (air-voids / in-situ density) spec rather than a method spec for winter working — it gives you both a defensible line.
