Becker Penetration Test (BPT) is a field test used for estimation of relative density of coarse-grained material containing cobbles and boulders. NovoBPT is designed for correcting raw BPT blow counts (Nb) and correlating them to SPT blow counts (N60). Supports bounce chamber pressure correction. Correlation to N60 based on: Harder and Seed, 1986; and Sy and Campanella, 1993b considering the effect of casing friction.
