The primary aim of this study is to correlate the impact of aggregates, if any, on the viscoelastic behavior of rejuvenated asphalt mixtures containing very high amounts of reclaimed asphalt pavement (RAP) (> 50%). First, gradation of 100% RAP was rectified, using a modified Bailey method by adding virgin aggregates to achieve two coarse dense-graded and one fine dense-graded blends. Complex modulus test was then performed from −35 to +35 °C and 0.01–10 Hz. In addition to performance grade (PG) testing, extracted and recovered binders from different asphalt mixtures underwent shear complex modulus test within −8 °C to high temperature PG and frequencies from 0.001 to 30 Hz. Cole–Cole, Black space, complex modulus and phase angle master curves were constructed and Shift-Homothety-Shift in time-Shift (SHStS) transformation was used to compare the linear viscoelastic behavior of asphalt binders and mixtures. The influence of aggregates on the viscoelastic behavior of asphalt mixtures depends on temperature and/or frequency. The role of asphalt binders in the behavior of asphalt mixtures is more pronounced at high temperatures and the effect of the aggregate structure increases as the temperature falls. The maximum difference (60% to 70%) in the viscoelastic behavior of the binder and mixture based on SHStS transformed Cole–Cole curves is within the phase angle of 15°–20°.

本研究的主要目的是关联集料（如果有）对含有大量再生沥青路面 (RAP)（> 50%）的再生沥青混合料的粘弹性行为的影响。首先，使用改进的贝利法，通过添加原始骨料，对 100% RAP 的级配进行校正，以获得两种粗密级配和一种细密级配的混合物。然后在 -35 至 +35 °C 和 0.01–10 Hz 范围内进行复数模量测试。除了性能等级（PG）测试外，从不同沥青混合料中提取和回收的粘结剂还进行了-8°C至高温PG和0.001至30 Hz频率范围内的剪切复数模量测试。科尔-科尔，黑色空间，构建了复数模量和相角主曲线，并使用时移-同位-移移 (SHStS) 变换来比较沥青粘合剂和混合物的线性粘弹性行为。集料对沥青混合料粘弹性行为的影响取决于温度和/或频率。沥青结合料在沥青混合料性能中的作用在高温下更加明显，并且随着温度下降，骨料结构的影响增加。基于 SHStS 变换的 Cole-Cole 曲线，粘合剂和混合物的粘弹性行为的最大差异（60% 至 70%）位于 15°–20° 的相角内。集料对沥青混合料粘弹性行为的影响取决于温度和/或频率。沥青结合料在沥青混合料性能中的作用在高温下更加明显，并且随着温度下降，骨料结构的影响增加。基于 SHStS 变换的 Cole-Cole 曲线，粘合剂和混合物的粘弹性行为的最大差异（60% 至 70%）位于 15°–20° 的相角内。集料对沥青混合料粘弹性行为的影响取决于温度和/或频率。沥青结合料在沥青混合料性能中的作用在高温下更加明显，并且随着温度下降，骨料结构的影响增加。基于 SHStS 变换的 Cole-Cole 曲线，粘合剂和混合物的粘弹性行为的最大差异（60% 至 70%）位于 15°–20° 的相角内。
