High-toughness noise-reduction semi-flexible pavement and preparation method thereof
The invention discloses a high-toughness noise-reduction semi-flexible pavement and a preparation method thereof.The pavement is prepared by pouring an asphalt mortar grouting material into a large-gap cement concrete matrix, the asphalt mortar grouting material comprises, by mass, 5.5-6.5% of emulsified asphalt, 0.5-1.5% of natural sand, 0.5-1.5% of rubber particles and 0.5-1.5% of rubber oil, and the mass ratio of the emulsified asphalt to the natural sand to the rubber particles to the rubber oil is 100%. The mass ratio of the natural sand is 80%-86%, the mass ratio of the rubber particles is 6%-12%, and the mass ratio of the rubber oil is 1.5%-2.5%. The elastic performance of the rubber particles is utilized, the toughness of the bottom of the base body is effectively improved, meanwhile, energy borne by the structure is converted into elastic energy, the purposes of reducing noise and protecting the safety of the structure are achieved, the high toughness and noise reduction of the semi-flexible pavement are improved, meanwhile, carbon emission of semi-flexible pavement construction is effectively reduced, and remarkable social and economic benefits are achieved.
本发明公开一种高韧降噪半柔路面及其制备方法，所述路面由大空隙水泥混凝土基体灌注沥青砂浆灌浆料制备而成，所述沥青砂浆灌浆料包括乳化沥青、天然砂、橡胶颗粒和橡胶油,所述乳化沥青的质量占比为5.5％～6.5％，所述天然砂的质量占比为80％～86％，所述橡胶颗粒的质量占比为6％～12％，所述橡胶油的质量占比为1.5％～2.5％。本发明利用橡胶颗粒的弹性性能，有效提高基体底部韧性，同时将结构受到的能量转化为弹性能，达到降低噪音与保护结构安全性的目的，在提升半柔路面高韧降噪的同时，有效减少半柔路面建设碳排放，具有显著的社会经济效益。
