Field, in-place repetitive static plate load tests are used for the evaluation and design of pavement structures. Repetitive static plate load tests are performed on soils and unbound base and subbase materials to determine a measure of the shear strength of pavement components.

1.1 This test method covers a procedure for making repetitive static plate load tests on subgrade soils and compacted pavement components, in either the compact condition or the natural state, and provides data for use in the evaluation and design of rigid and flexible-type airport and highway pavements.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
