ASTM D7369-20 PDF Download

The ASTM D7369-20 standard provides a procedure for evaluating the resilient modulus of asphalt mixtures. Resilient modulus is an important parameter used in assessing the quality of materials and for pavement design, evaluation, and analysis. This test method also allows for the investigation of the effects of temperature and load on the resilient modulus.

The standard specifies that the test can be conducted on laboratory-fabricated or field-recovered asphalt mixture cores. The cores are subjected to a repeated-load indirect tension test to determine the resilient modulus values. However, it should be noted that this standard does not provide a precision and bias statement at this time, so it should not be used for acceptance or rejection of materials for purchasing purposes.

The standard emphasizes that the accuracy of the test results depends on the competence of the personnel conducting the procedure and the calibration and maintenance of the equipment used. It also highlights that compliance with Specification D3666, or a similar acceptable guideline, is necessary but not sufficient to ensure reliable results. Following the suggestions of such guidelines provides a means of evaluating and controlling various factors that can affect the reliability of the test results.
