High-performance asphalt concrete pavement material and preparation method thereof
The invention relates to the technical field of pavement materials, in particular to a high-performance asphalt concrete pavement material and a preparation method thereof. The formula of the pavement material comprises asphalt, high-melt-index SBS, fine aggregate, coarse aggregate, fly ash, a water reducing agent, a low-temperature anti-cracking agent and an anti-freezing agent. The preparation method of the low-temperature anti-cracking agent comprises the following steps: stirring homo-polypropylene, nano silicon carbide and low-melt-index SBS, and carrying out extrusion spinning to obtain the low-temperature anti-cracking agent. By optimizing the proportion and adding specific components, the material has good low-temperature anti-cracking performance, anti-freezing performance and anti-stripping performance. The high-performance asphalt concrete pavement material provided by the invention is expected to be applied to the fields of highway engineering and road construction in low-temperature areas.
本发明涉及路面材料技术领域，具体涉及一种高性能沥青混凝土路面材料及其制备方法。该路面材料的配方包括沥青、高熔融指数SBS、细骨料、粗骨料、粉煤灰、减水剂、低温抗裂剂和抗冻剂。其中，低温抗裂剂的制备方法包括将均聚聚丙烯、纳米碳化硅和低熔融指数SBS进行搅拌和挤出纺丝，得到低温抗裂剂。通过优化配比和添加特定成分，该材料具有良好的低温抗裂性能、抗冻性能和抗剥落性能。本发明提供的高性能沥青混凝土路面材料有望应用于低温区域的公路工程和道路建设领域。
