The invention provides cold-mix type colored epoxy asphalt, a compatibilizing agent and a preparation method. The cold-mix type colored epoxy asphalt is composed of a component A and a component B inparts by weight, wherein the component A comprises 95 to 112 parts of a colored asphalt material, 30 to 80 parts of a cold-mix type colored epoxy asphalt compatibilizing agent and 40 to 100 parts of modified epoxy resin; and the component B comprises 30 to 100 parts of a composite curing agent used for cold-mix type epoxy asphalt. The preparation method comprises the following steps: adding a baseoil component, a functional grafting agent and an initiator which are prepared in proportion into a stirring tank in sequence, carrying out stirring at a temperature of 25 to 150 DEG C and a stirringspeed of 800 to 1500 rpm for 1 to 5 h, and carrying out cooling so as to obtain the compatibilizing agent; preheating 100 parts of the colored asphalt material to 100 to 140 DEG C, adding 60 parts ofthe compatibilizing agent into the preheated colored asphalt material, carrying out shearing and mixing for 2 to 4 h, then carrying out cooling to 40 to 80 DEG C, adding 80 parts of the modified epoxy resin, and continuing shearing and mixing for 1 to 2 h so as to obtain the component A; and mixing the prepared component A with 70 parts of the composite curing agent, and carrying out stirring ata room temperature for 5 to 15 min so as to obtain the cold-mix type colored epoxy asphalt.
