Waterproof high-strength basalt fiber asphalt mixture and preparation method thereof
The invention relates to the technical field of asphalt modified materials, and discloses a waterproof high-strength basalt fiber asphalt mixture and a preparation method thereof. The waterproof high-strength basalt fiber asphalt mixture is prepared from the following components in parts by weight: 4 to 5 parts of SBS modified asphalt, 0.3 to 0.5 part of modified basalt fiber, 90 to 93 parts of aggregate and 1 to 3 parts of mineral powder. The preparation method comprises the following steps of: baking and heating SBS modified asphalt until the SBS modified asphalt is molten; respectively heating and drying the aggregate and the mineral powder to constant weight; and mixing the aggregate and the modified basalt fiber, adding the molten SBS modified asphalt, continuing to mix, and adding the mineral powder to mix, thereby obtaining the product. In the mixture prepared by the invention, the SBS modified asphalt and the aggregate as well as the SBS modified asphalt and the basalt fiber have relatively strong bonding performance; the phenomenon that rainwater erodes the mixture to cause stripping between the aggregate and basalt fiber and the SBS modified asphalt is avoided, the waterproof performance of the asphalt mixture is improved, and the service life of the asphalt mixture is prolonged.
本发明涉及沥青改性材料技术领域，公开了一种防水高强度玄武岩纤维沥青混合料及其制备方法。防水高强度玄武岩纤维沥青混合料包括按重量份计的下述组分：SBS改性沥青4‑5份，改性玄武岩纤维0.3‑0.5份，集料90‑93份，矿粉1‑3份；先将SBS改性沥青置于烘加热至熔融；然后将集料和矿粉分别加热烘干至恒重；再将集料和改性玄武岩纤维进行拌合，加入熔融态SBS改性沥青继续拌合，加入矿粉拌合，即得。本发明制备得到的混合料中SBS改性沥青与集料之间、SBS改性沥青与玄武岩纤维之间具有较强的粘结性能，避免雨水对混合料侵蚀造成集料和玄武岩纤维与SBS改性沥青之间出剥离现象，提高提高沥青混合料的防水性能，进而延长沥青混合料的使用寿命。
