橡胶颗粒沥青混合料破冰试验研究

Ice Breaking Test of Rubber Particle Asphalt Mixture

橡胶颗粒沥青混合料具有较好的破除路面冰雪的性能,文章针对其破冰性能进行了一系列的试验研究,利用BPN及其衰减量定量描述各种路面的破冰能力。试验结果表明,橡胶颗粒沥青混合料试板与不含橡胶颗粒的混合料试板相比,其破冰能力显著,当橡胶颗粒含量在4%以下时,随着颗粒含量的增加,其破冰的能力越强。并且橡胶颗粒粒径越大,其试验效果越明显。

Granulated crumb rubber asphalt mixture material has better performance in breaking the ice and snow on the road. This paper shows a series of experimental study aimed at the ice breaking performance, using BPN and attenuation reduction quantitative description of various pavement icebreaking capability. The test results show that the rubber particle bituminous mixture test plate break ice significantly compared to the test plates without mixture of rubber particles. When the content of rubber particles is less than 4%, with increase of the content of particles, the ice breaking ability will be stronger. And the bigger the size of rubber particles is, the more obvious the test results are.
