The invention discloses a modified asphalt cold patch material which is prepared from the following raw materials in parts by weight: 90-96 parts of aggregate and 4-10 parts of cold patch asphalt. Thecold patch asphalt is prepared from the following raw materials in parts by weight: 60-65 parts of asphalt, 30-40 parts of diesel oil, 0.1-0.3 parts of a modifier and 1-2 parts of an additive. The asphalt is selected as a matrix raw material, diesel oil is selected to destroy the molecular structure of the asphalt, then the modifier is used for improving the original performance of the asphalt, and finally the additive is used for improving the coagulability of the finished product during construction. According to the invention, the modifier is added into the modified asphalt cold patch material, a linear SBS modifier and a star-shaped SBS modifier are selected as main modifiers, a stabilizer is used as an auxiliary material, the compatibility of SBS and asphalt is improved, asphalt segregation is prevented, and the utilization efficiency of SBS is improved; and modified epoxy resin is added, so that the bonding performance of the modified asphalt cold patch material is greatly improved.
本发明公开了一种改性沥青冷补料，由以下重量份原料制成：90~96份集料、4~10份冷补沥青；所述冷补沥青由以下重量份原料组成：60~65份沥青、30~40份柴油、0.1~0.3份改性剂、1~2份添加剂。本发明选用沥青作为基质原料，选用柴油来破坏沥青的分子结构，再用改性剂来改良沥青的原有性能，最后再用添加剂来达到改良成品施工的凝结性；本发明通过在改性沥青冷补料中加入改性剂，并选用线型SBS改性剂、星型SBS改性剂为主要改性剂，并辅以稳定剂，提高SBS与沥青的相容性，防止沥青离析，提高SBS的利用效率，并在其中加入改性环氧树脂，极大的增强了改性沥青冷补料的粘结性能，冷补后。
