Porous ceramsite asphalt mixture as well as preparation method and application thereof
The invention provides a porous ceramsite asphalt mixture as well as a preparation method and application thereof, and relates to the technical field of pavement materials. The porous ceramsite asphalt mixture provided by the invention comprises the following components in percentage by mass: 18.5%-30.5% of pretreated porous ceramsite, 5%-5.5% of high-viscosity and high-elasticity modified asphalt and 64%-76% of supplementary mineral aggregate, the pretreated porous ceramsite comprises porous ceramsite and a snow melting agent loaded on the porous ceramsite. An ice-inhibiting and snow-melting layer paved by the porous ceramsite asphalt mixture provided by the invention has a relatively good inhibiting effect on a thin ice phenomenon on the surface of a road in early winter and spring melting periods, the interface bonding strength of the road surface and ice and snow is reduced under a heavy snow condition, ice and snow are easy to remove, the ice and snow removing efficiency is improved, and the cost is reduced.
本发明提供了一种多孔陶粒沥青混合料及其制备方法和应用，涉及路面材料技术领域。本发明提供的多孔陶粒沥青混合料，以质量百分数计，包括预处理多孔陶粒18.5％～30.5％，高黏高弹改性沥青5％～5.5％，补充矿料64％～76％；所述预处理多孔陶粒包括多孔陶粒以及负载在所述多孔陶粒上的融雪剂。采用本发明提供的多孔陶粒沥青混合料铺设的抑冰融雪层对于初冬及春融期路表薄冰现象有较好的抑制作用，大雪条件下降低路面与冰雪的界面粘结强度，易于除冰雪，提高除冰雪的效率并降低费用。
