[0037]An environment-friendly road surface quick repair material preparation method includes the following steps:
[0038](1) Preparation of anti-aging agent: take carbon black, waste tire rubber powder and organic montmorillonite in a planetary ball mill at a revolution speed of 200-250 rpm, a rotation speed of 300-350 rpm, and ball mill for 10-12 hours to obtain the anti-aging agent;
[0039](2) Acquisition of aggregate: the old asphalt pavement milling material is recovered, crushed, screened, and mixed with new aggregates if necessary to make the gradation conform to the "Technical Specification for Highway Asphalt Pavement Construction" JTGF40-2004 (5.3.2) ) AC-13 gradation range in Table 5.3.2-2, the specific gradation range is shown in Table 1;
[0040](3) Modification of epoxy resin: Take epoxy resin and place it in a planetary ball mill, add modifier to it, revolution speed 100~150rpm, rotation speed 240~260rpm, ball mill for 6~8h to obtain modified epoxy resin ;
[0041](4) Stirring: ...

[0043]An environment-friendly rapid repair material for pavement is prepared as follows:
[0044](1) Preparation of anti-aging agent: Weigh 1.5 kg of carbon black, 2.75 kg of waste tire rubber powder and 0.25 kg of organic montmorillonite in a planetary ball mill, revolution speed 200 rpm, rotation speed 300 rpm, and ball mill for 10 hours to obtain anti-aging agent ;
[0045](2) Acquisition of aggregate: the old asphalt pavement milling material is recycled, crushed, sieved, and blended with the new aggregate. The resulting aggregate is in accordance with the "Test Regulations for Highway Engineering Asphalt and Asphalt Repair Materials" JTGE20-2011 (T0725- 2000) Carry out gradation inspection, and the results of aggregate gradation inspection and analysis that meet the gradation requirements are shown in Table 2:
