Asphalt mixture modified by compounding waste printed circuit board nonmetal powder with SBS (styrene butadiene styrene)
The invention discloses a waste printed circuit board non-metal powder compounded SBS modified asphalt mixture which comprises 2%-3% of an SBS modifier, 20%-30% of waste printed circuit board non-metal powder and 3%-5% of a compatilizer. The prepared waste printed circuit board non-metal powder compounded SBS modified asphalt is used for preparing an asphalt mixture and comprises the following components in percentage by mass: 3.8-4.6% of waste printed circuit board non-metal powder compounded SBS modified asphalt and 95.4-96.2% of mineral aggregate, and the cost can be effectively reduced by partially replacing an SBS modifier; meanwhile, the performance of the modified asphalt reaches or exceeds that of equivalent SBS modified asphalt. The preparation method of the modified asphalt is simple, the prepared modified asphalt has the excellent characteristics of good storage stability, good rutting resistance, good water-resistant stability, good economic benefits and the like, and the technical problems of environmental protection, resource conservation, cyclic utilization and the like are solved.
本发明公开了一种用废旧印刷线路板非金属粉复配SBS改性沥青混合料，SBS改性剂2％～3％，废旧印刷线路板非金属粉20％～30％，相容剂3％～5％；将制备的废旧印刷线路板非金属粉复配SBS改性沥青用于制备沥青混合料，以质量百分比计，废旧印刷线路板非金属粉复配SBS改性沥青3.8％～4.6％，矿料95.4％～96.2％，并通过部分替代SBS改性剂能有效降低成本，同时使改性沥青的性能达到或超过等量SBS改性沥青的性能。本发明改性沥青的制备方法简单，制备的改性沥青具有储存稳定性好、抗车辙性能好、抗水稳定性和经济效益好等优异的特点，并克服环境保护、资源节约与循环利用等技术难题。
