AASHTO T 386-19 PDF Download

AASHTO T 386-19 is a standard method of testing deep foundation units to assess their ability to withstand compressive loads. The standard provides guidelines for conducting rapid axial load tests on vertical or inclined piles.

The purpose of the test is to determine the displacement response of the foundation unit when subjected to a sudden compressive load of a predetermined peak force. This test method is suitable for all types of deep foundation units that function similarly to piles, regardless of the method of installation.

The standard outlines the procedure for setting up the test, including the required equipment and instrumentation. It specifies the load pulse characteristics, such as peak force and duration, as well as the number of repetitions to be conducted. The standard also provides guidelines for data collection and analysis, including the measurement of displacement, force, and time.
