Standard Method of Test for
Nonrepetitive Static Plate Load Test of Soils and
Flexible Pavement Components for Use in Evaluation and
Design of Airport and Highway Pavements
AASHTO Designation: T 222-81 (2004)
1.1.This method covers the making ofnonrepetitive static plate load test on subgrade soils and flexible pavement components, in either the compacted condition or
the natural state, and is intended to provide data for use in the evaluation and design of rigid and flexible-type airport and highway pavements.
1.2.The values stated in SI units are to be regarded as the standard.
2.1.deflection-the amount of downward vertical movement of a surface due to the application of a load to the surface.
2.2.residual deflection-the difference between original and final elevations of a surface resulting from the application and removal of one or more loads to and from the surface.
2.3.rebound deflection-the amount of vertical rebound of a surface that occurs when a load is removed from the surface.
