Ice and snow melting asphalt-rich mixture
The invention discloses an ice and snow melting rich asphalt mixture, which is characterized in that aggregate grading design of coarse aggregate, fine aggregate and mineral powder is carried out by a CAVF method, the coarse aggregate adopts 10-15mm broken stone and 5-10mm broken stone, the fine aggregate adopts 0-5mm sand, and the apparent density of the mineral powder is greater than or equal to 2.5 g/cm < 3 >; the use amount of the asphalt is 4.5-5.0% of the mass of the aggregate, and MFL is doped to replace part or all of the mineral powder; after the MFL is doped, the aggregate comprises the following components in percentage by mass: 51-52% of broken stones with the particle size of 10-15 mm, 27-28% of broken stones with the particle size of 5-10 mm, 13.0-13.1% of sand with the particle size of 0-5 mm, 2.5-7.5% of MFL and 0-6.0% of mineral powder; the average gross volume relative density of the coarse aggregate skeleton is smaller than the void ratio of the main aggregate, and the ice and snow melting asphalt-rich mixture can form a skeleton embedding and extruding structure. Various pavement performances of the MFL asphalt-rich mixture with different mixing amounts meet SMA mixture specification requirements, and the MFL asphalt-rich mixture can be used for solving the problem of ice melting and snow melting of urban roads in winter.
本发明公开了一种融冰雪富沥青混合料，由CAVF法进行包括粗集料、细集料和矿粉的集料级配设计，其中粗集料采用10‑15mm碎石和5‑10mm碎石，细集料采用0‑5mm砂，矿粉的表观密度≥2.5g/cm3；沥青用量为集料质量的4.5～5.0％，并掺入MFL代替部分或全部的矿粉；掺入MFL之后，集料中各组分质量百分比为10‑15mm碎石：5‑10mm碎石：0‑5mm砂：MFL：矿粉＝51～52％：27～28％：13.0～13.1％：2.5～7.5％：0～6.0％；粗集料骨架的平均毛体积相对密度小于主骨料空隙率，融冰雪富沥青混合料可形成骨架嵌挤结构。本发明不同掺量MFL富沥青混合料各项路用性能均满足SMA混合料规范要求，可用于解决城市道路冬季融冰化雪的难题。
