The outcomes could facilitate tailoring CEAM products with better long-term performance. The improved long-term performance actually originated from the reduced voids and produced a dense microstructure. The mixture incorporating 90 wt% OPC and 10 wt% SAC demonstrated excellent rutting resistance up to ~ 31,000 cycles/mm of dynamic stability. The experimental results revealed that the relative dynamic elastic modulus of CAEM was increased to 69.7% when admixing 90 wt% OPC and 10 wt% SAC. Three tasks were conducted, including (1) designing six CAEM formulations by introducing different types (OPC and SAC) and contents (2–6 wt%) of cement (2) evaluating the long-term performance by moisture susceptibility, frost damage, abrasion resistance, and rutting resistance and (3) characterizing the microstructural properties by scanning electron microscopes and energy-dispersive spectrometers. This study explored the effect of the combined usage of ordinary portland cement (OPC) and sulfoaluminate cement (SAC) on the long-term performance and microstructural properties of a CAEM system in detail. However, the long-term performance of the CAEM incorporating multiple cement combinations is not conclusive. Cement has been well documented to positively affect the early-age strength of the cement asphalt emulsion mixtures (termed as CAEM) without compromising workability.
