摘要: This paper addresses the development and evaluation of a mix stability index referred to as gyratory (GS). GS is calculated from compaction data by summing cumulative energies dissipated in sample. A wide range commonly used mixes State Idaho were selected for evaluation. Mixes tested dynamic modulus (E*) flow number (F N); rutting was measured with asphalt pavement analyser (APA). Furthermore, E* test results AASHTO Mechanistic–Empirical Pavement Design Guide (MEPDG) level 1 inputs, predict these mixes; ranked similarly APA F N tests MEPDG results. indicated that has potential be screening tool design, especially decide upon acceptance aggregate structure, quality control tool.
