Stone mastic asphalt mixture using recycled fan blade waste as filler
The invention relates to a stone mastic asphalt mixture using recycled fan blade waste as a filler. The mixture comprises the following components in parts by weight: 6-9 parts of SBS modified asphalt, 8-12 parts of lignin fibers and fan fibrous waste, 100-150 parts of crushed stones, 4-6 parts of fan powder waste and 1-5 parts of fan blocky waste. In the mixture, the particle size of the fan powder waste is smaller than 0.075 mm, the particle size of the fan fiber waste is larger than or equal to 0.075 mm and smaller than 9.5 mm, the length-width ratio of the fan fiber waste is larger than 10, the particle size of the fan block waste is greater than or equal to 9.5 mm, aggregate except asphalt in the stone mastic asphalt mixture meets the grading requirement of the national stone mastic asphalt mixture, and the SBS modified asphalt adopts No.90 matrix asphalt. By means of the size synergistic effect of the fan fiber waste materials of various sizes, the fan blade waste materials, thelignin fibers and the crushed stone aggregates form a better interlocking framework structure and dense filling in the stone mastic asphalt mixture, and the anti-cracking performance and the anti-rutting performance of the material are improved.
本发明为一种用回收风机叶片废料作为填料的沥青玛蹄脂碎石混合料，以重量份计，包括如下组分：SBS改性沥青6～9份,木质素纤维和风机纤维状废料的总份数为8～12份,碎石料100～150份，风机粉末废料4～6份，风机块状废料1～5份；上述混合料中，所述风机粉末废料的粒径＜0.075mm；风机纤维废料粒径满足0.075mm≤粒径＜9.5mm，且风机纤维废料的长宽比>10；风机块体废料的粒径≥9.5mm；沥青玛蹄脂碎石混合料中除沥青外的集料满足国家沥青玛蹄脂碎石混合料的级配要求，SBS改性沥青采用90号基质沥青。利用多种尺寸的风机纤维废料的尺寸协同效应，使风机叶片废料、木质素纤维、碎石集料在沥青玛蹄脂碎石混合料内部形成更加良好的嵌锁骨架结构和密实充填，提高材料抗裂性能和抗车辙性能。
