Webthe Standard Penetration Test (N), which is basically a super heavy dynamic probe test, is reported to be between 27 and 85% with a recommended standard of 30%, (Lee et al. 1983). The repeatability of SPT test results could be used as a measure of the repeatability of Mackintosh Probe results by comparing the C v values of the two methods. Web• The Standard Penetration Test, or SPT, is the most widely used in-situ test, in Hong Kong and throughout the world, as an indicator of the density and compressibility of granular soils. It is also commonly used to check the …
