ASTM D4123 PDF

Permissions to reprint documents can be acquired through Copyright Clearance Center ASTM License Agreement Withdrawn Rationale: This test method covers procedures for preparing and testing laboratory-fabricated or field-recovered cores of bituminous mixtures to determine resilient modulus values using the repeated-load indirect tension test. The procedure described covers a range of temperatures, loads, loading frequencies, and load durations. The recommended test series consists of testing at 41, 77 Note 1 , and F 5, 25 Note 1 , and 40C at one or more loading frequencies, for example, at 0. This recommended series will result in nine test values for one specimen which can be used to evaluate the overall resilient behavior of the mixture.

More D This practice is limited to only fine-grained soils as defined in 6. Note 1—The quality of the results produced by this practice is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing, sampling, inspection, and so forth.

Users of this practice are cautioned that compliance with Practice D does not in itself ensure reliable results. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Scope 1. 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.

In this system, the pound lbf represents a unit of force weight while the unit for mass is slugs. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. 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.

The system should be capable of measuring horizontal deformations in the range of 0. Loads should be D measured and recorded or accurately calibrated prior to testing. The sensitivity and type of measurement device should be selected to provide the defor- mation readout required in 5. A positive contact by spring loading or gluing attachments to the specimen should be provided if direct contact between the measuring device and sample is required.
