Dec 07, 2005· A subgrade modulus for rock is not of much use. The modulus is defined as pressure/measured deflection. Rock, unlike soil, does not compress when pressure is applied (i.e. it will crack before its compressibility can be mearured). Thus, the rock will experience a brittle fracture failure instead of a slow compression as can be seen in most soils.
