Cold-mix type colored epoxy asphalt, compatibilizing agent and preparation method

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 i
