Moule CBR BS

CBR Mould is machined to an internal diameter of 152 mm and a body height of 127 mm, and is supplied with a 51 mm extension collar and perforated/solid base plates. The rigid steel body, corrosion-resistant galvanized coating, and precision-machined mating faces ensure mould geometry is preserved under compaction blows, maintaining consistent volume–height tolerances for each specimen. The upper and lower faces are machined for tight, gap-free seating. A wing-nut clamping system allows tool-free assembly; the perforated base plate provides drainage, while the solid base plate is preferred for swell measurement and protective configurations.
