A technical note by Tim that appeared in the December 2010 issue of the DFI Journal has been added to our publications page. Tim’s note examines some issues related to axial load testing of augered cast-in-place (ACIP) piles, also know as augercast piles or CFA piles, that are not covered in ASTM D 1143/D 1143M-07 Standard Test Methods for Deep Foundations Under Static Axial Compression. Specifically, load hold time, unload-reload cycles, and fluctuations in incremental load are discussed as they relate to load testing for determining axial capacity or axial load distribution of ACIP piles. Details of instrumented ACIP pile load testing are also covered.
