The invention discloses epoxy asphalt for a gravel sealing layer, a gravel sealing layer material and a gravel sealing layer method. The epoxy asphalt for the gravel sealing layer is prepared from the following raw materials by weight percent: 50.0%-80.0% of epoxy resin, 10.0%-30.0% of curing agent, 5.0%-15.0% of asphalt and 5.0%-15.0% of additive, wherein the epoxy resin is bisphenol A type epoxy resin; the curing agent is prepared from polyamide and triethylene tetramine or diethylene triamine at a weight ratio of 2:1; the additive is phthalate; and the asphalt is No.70 paving asphalt. The invention also discloses the gravel sealing layer material which is prepared from the epoxy asphalt and gravel at a weight ratio of 1:(3-5) and the gravel sealing layer method of the gravel sealing layer material. By adopting the epoxy asphalt, the adhesive property of asphalt can be increased and the gravel on a asphalt pavement can be prevented from coming off.
