Optimisation of ballast compaction by continuous monitoring of ground stiffness

In the past year Network Rail has been using the Bomag Variomatic BW213DH4 BVC/P (BOMAG) roller to provide optimum compaction to ballast (and formation where possible) during track renewals. The BOMAG’s inbuilt instrumentation and control systems permit continuous monitoring of ground stiffness and delivery of an optimum amount of compactive...
