Conventional quality control of compaction during construction is currently based on an in-situ determination of dry unit weight and moisture content via nuclear procedures, but because this is a localised procedure, poor compaction can often occur. Moreover, with older compacted embankments where few or no records of the control done during construction are available, there is no existing methodology that can help practising engineers assess their post-construction condition. This means that the scope of the nuclear method renders it as inadequate and alternative methods should be considered. The use of shear wave velocity (Vs) surveys (i.e. MASW) to assess the …
