AASHTO T 298 – Standard Method of Test for High-Strain Dynamic Testing of Piles

This test method covers the procedure for testing vertical or batter piles individually to determine the force and velocity response of the pile to an impact force applied axially by a pile-driving hammer to the top of the pile. This test method is applicable to deep foundation units that function in a manner similar to foundation piles, regardless of their method of installation, provided that they are receptive to high-strain impact testing. These elements can include drilled shafts, micropiles, and continuous flight auger cast piles.

Except for Section 5.2, this standard is in general conformance to ASTM D 4945.
