A mechanical model of cement and emulsified asphalt mortar (CA) from four different levels (i.e., cement hydration products, cement gel skeleton, cement asphalt composite system and CA mortar) was proposed based on the microscopic experimental results by backscatter electron imaging and X-ray diffraction and the Hashin composite ball model. The relationships among the elastic modulus of CA mortar, compressive strength f and composition parameters were investigated. The results show that the volume fraction of cement hydrate phase is an important parameter affecting the CA mortar elastic modulus and the compressive strength f. When asphalt is regarded as a pore or a low modulus component, the static elastic modulus of the CA mortar and the volume fraction of cement hydrate, compressive strength f and gel-space ratio all have a power function relationship > 0.8. The cement hydrate in the CA mortar is still a continuous phase and constitutes the composite gel skeleton, asphalt interspersing among them, and the contribution of asphalt to the CA mortar strength and elastic modulus is relatively low.
