ASTM E2835-21

4.1?This test method covers the determination of plate deflection resulting from the application of an impulse load. The deflection is measured at the center of the top of the load plate (see Note 1).

4.2?Deflections may be either correlated directly to pavement performance or used to determine in-situ material characteristics of the pavement foundation layers. Some uses of the data include quality control and quality assurance of compacted layers, and for structural evaluation of load carrying capacity (see Note 2 and Guide D4695).

1.1?This test method applies to measuring plate deflections using a Portable Impulse Plate Load Test device. The method covers the measurement of deflection of the load plate rather than the deflection of the surface of the pavement or foundation layers (see Note 1).

1.2?The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
