Abstract	This study investigates the deformation behaviors of cement emulsified asphalt composite materials (CEACM) with varied cement content. Repeated creep test is implemented to measure the evolution of accumulated strains ( $$\gamma_{\text{acc}}$$ ) with accumulated creep time. Burgers model and piecewise curve fitting are used to obtain the viscous component of creep stiffness ( $$G_{\text{v}}$$ ) and creep compliance. The strain–time curves show that the $$\gamma_{\text{acc}}$$ decrease significantly and creep-recovery ratios increase gradually with the increase of C/A. The analysis of $$G_{\text{v}}$$ and creep compliance illustrates that the $$G_{\text{v}}$$ of CEACM increase by orders of magnitude. A cement asphalt ration (C/A) of 1.0 maximizes the elastic component. Incidentally, for C/A is 1.2, the CEACM demonstrate remarkably rigid behavior.
