Examples
Embodiment 1
[0032] Example 1, a regenerative road cold patch material, the raw material components are shown in Table 1 in parts by weight. Wherein, the cold patch is prepared through the following steps:
[0033] Step 1: Heat base asphalt and planing and milling material to 120-140°C, add kerosene and stir for 20-30 minutes, then add cold patching additives and keep warm to 100°C to obtain diluted asphalt;
[0034] Step 2, the polyurethane prepolymer, water-based epoxy resin and octadecyltrimethylammonium chloride are dropped into the diluted asphalt and stirred evenly to obtain the mixture;
[0035] Step 3, putting styrene-butadiene-styrene block copolymer and dicumyl peroxide into the cold repair mixture and stirring evenly to obtain the modified mixture;
[0036] In step 4, limestone is put into the modified mixture for mixing and stirring to obtain cold patching material.
Embodiment 2
[0037] Embodiment 2 differs from Embodiment 1 in that, in parts by weight, the raw material components are as shown in Table 1.
Embodiment 3
[0038] Example 3, a regenerative road cold patch material, the raw material components are shown in Table 1 in parts by weight. Wherein, the cold patch is prepared through the following steps:
[0039]Step 1: Heat base asphalt and planing and milling material to 120-140°C, add kerosene and stir for 20-30 minutes, then add cold patching additives and keep warm to 100°C to obtain diluted asphalt;
[0040] Step 2, putting the polyurethane prepolymer and octadecyltrimethylammonium chloride into the diluted asphalt and stirring evenly to obtain the mixture;
[0041] Step 3, putting styrene-butadiene-styrene block copolymer and dicumyl peroxide into the cold repair mixture and stirring evenly to obtain the modified mixture;
[0042] In step 4, limestone is put into the modified mixture for mixing and stirring to obtain cold patching material.
