1.1本试验方法涵盖了制备和测试实验室制造或现场恢复的沥青混合料芯的程序，以使用重复荷载间接拉伸试验确定弹性模量值。所述程序涵盖一系列温度、负载、负载频率和负载持续时间。推荐的测试系列包括在41、77（注1）和104°F（5、25（注1）和40°C）下，在一个或多个加载频率下进行测试，例如，在每个温度下在0.33、0.5和1.0 Hz下进行测试。本推荐系列将为一个样本得出九个测试值，可用于评估混合物的整体弹性行为。 注1:实验室环境温度可酌情替代。 1.2本标准可能涉及危险材料、操作和设备。本标准并非旨在解决与其使用相关的所有安全问题。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 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 104°F (5, 25 (Note 1), and 40°C) at one or more loading frequencies, for example, at 0.33, 0.5, and 1.0 Hz for each temperature. 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. Note 1-Ambient laboratory temperature may be substituted as appropriate. 1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
