Rapid Load Testing (RLT), by which a quasi-static load is applied to a foundation pile, is used increas- ingly as an alternative to static load testing (SLT) and high strain dynamic testing (HSDT), commonly re- ferred to as dynamic load testing (DLT), for cast in- situ piles, such as drilled shafts. It is recognized now- adays that the determination of the pile capacity with DLT through signal matching techniques such as CAPWAP, TNOWAVE and AllWave-DLT yield a wide spread of results (Stahlmann et. Al, 2012), mak- ing it practically impossible to calibrate the DLT results with SLT results. This spread is due to the em- pirical and very subjective assumptions that are used to interpret the test data, irrespective of pile type, but especially for cast in-situ piles (Holeyman et al. 2001, Viana da Fonseca in 2008, Herten et al, 2013).
