“…The most common stabilization agents include emulsified asphalt, foamed asphalt, and cement [14,20,21]. Factors influencing the volumetric and mechanical properties of CRM were intensively investigated by many researchers, e.g., curing time and temperature [22][23][24], compacting method [25], cement content and type [26][27][28][29][30], RAP source and content [31,32], asphalt content [27,[33][34][35], gradation [21,25,36], water content [28,37], rejuvenator content [38], additive or active fillers [18,19,39,40], asphalt type, and extra aggregates [41]. At the same time, the effect of RAI or composite RAP/RAI on the performance, mechanical behavior, and small strain characteristic of CRM stabilized by emulsified asphalt or cement has been studied by many scholars [42,43].…”
