The characteristics of the magnesium phosphate cement has fast setting, high strength mixed with emulsified asphalt that mixtures can become the properties of firmness and flexibility. The mixtures as fast road repairing materials would be benefited the engineering properties of the Marshall stability value, shear strength, resistance to plastic flow and…etc. for specification required. The study designs to add three different ratios of fine aggregate for mixtures: (a) flexible pavement concepts sign as A-series; (b) rigid pavement concept sign as B-series; and (c) C-series used as fly ash. The properties of the fresh and hardened are tested as well. The results showed that only C-series type C-03 is satisfied by the specification of the flow of hydraulic cement mortar test and flow consistency test. The type of C-03 has the highest values in the Marshall stability values, indirect tensile strength and compressive strength after 28 days curing.
