本实施规程描述了用于开发混凝土动态模量主曲线的测试和分析 使用沥青混合料性能测试仪（AMPT）测试沥青混合料。这种做法是有意的 适用于标称最大骨料粒径不超过37.5 mm的密实级配和间隙级配混合料。这 实践说明了AMPT的温度限制，并为用户提供了指导 用于选择合适的试验温度。

This practice describes testing and analysis for developing a dynamic modulus master curve for asphalt mixtures using the Asphalt Mixture Performance Tester (AMPT). This practice is intended for dense- and gap-graded mixtures with nominal-maximum aggregate sizes up to 37.5 mm. This practice accounts for the temperature limitations of the AMPT and provides guidance to the user for the selection of appropriate test temperatures.
