Further, the weight percentage of each component in the component A is as follows: 63% of epoxy resin, 4% of plasticizer, 3% of allyl glycidyl ether, 12% of heavy calcium, 12% of talcum powder and 6% of pigment.
Preferably, the epoxy resin is bisphenol a type epoxy resin.
Preferably, the plasticizer is a polyol modification.
The preparation method of the cementing material for the cold-mix color water-permeable asphalt comprises the following steps:
1) Under the stirring condition, firstly adding epoxy resin and allyl glycidyl ether into a mixing kettle, stirring and mixing, and then slowly adding a plasticizer, stirring and mixing;

The plasticizer adopts a polyol modifier, in particular plant polyene phenol, and has the main functions of weakening secondary valence bonds, namely Van der Waals force, among bisphenol A type epoxy resin molecules, thereby increasing the mobility of polymer molecular chains, reducing the crystallinity of the polymer molecular chains, namely increasing the plasticity of the polymer, and improving the elongation, the flexibility and the toughness as shown by the reduction of the hardness, the modulus, the softening temperature and the embrittlement temperature of the polymer. The toughness of the concrete can be enhanced, so that the concrete is not easy to break under the action of pressure.
Allyl glycidyl ether action: the viscosity of the cementing material is reduced on the basis of little influence on the cementing material performance.
Talcum powder function: improving the stability and the anti-weathering capacity of the cementing material.
The heavy calcium can strengthen the concrete.
