Preparation method of epoxy modified cold patch asphalt mixture
The invention provides a preparation method of an epoxy modified cold patch asphalt mixture. The epoxy modified cold patch asphalt mixture is composed of a component A and a component B. The componentA is prepared from the following raw materials in parts by weight: 100 parts of stone and 6-10 parts of cold patch asphalt. The cold patch asphalt is prepared from the following raw materials in percentage by mass: 11%-23% of diesel oil, 2%-4% of polyamide, 2%-3% of ethyl cyanoacetate and 73%-82% of road petroleum asphalt. The component B is prepared from the following raw materials in parts by weight: 15-40 parts of diesel oil, 5-8 parts of arene-rich separated oil, 6-8 parts of paraformaldehyde and 44-70 parts of epoxy resin. The cold patch asphalt mixture is convenient to store, excellentin construction workability and low in cost, meanwhile, the high-temperature performance, the adhesion performance, the water damage resistance and the fatigue performance of the cold patch asphalt mixture are improved, the pavement performance of the asphalt mixture is remarkably improved, construction is facilitated, and the driving comfort of a repaired pavement is improved.
本发明提供一种环氧改性型冷补沥青混合料的制备方法，该混合料由A组分和B组分构成，所述A组分采用包括以下重量份的原料制成：石料：100份，冷补沥青：6～10份；所述冷补沥青由以下质量分数的原料制成：柴油：11%～23%，聚酰胺：2%～4%，氰乙酸乙酯：2%～3%，道路石油沥青：73%～82%；所述B组分采用包括以下重量份的原料制成：柴油：15～40份，富芳香分油：5～8份，多聚甲醛：6～8份，环氧树脂：44～70份，本发明的产品便于存储、施工和易性优良、成本低廉，同时改善冷补沥青混合料的高温性能、粘附性能、抗水损害性能及疲劳性能，显著提升沥青混合料的路用性能，便捷化施工，增大修补路面的行车舒适性。
