Pavement material
The invention provides a pavement material which comprises aggregate, the aggregate comprises at least nine grades, and the at least nine grades are as follows in sequence from large to small according to the aggregate particle size: 90%-100% of 13.2 mm, 50%-75% of 9.5 mm, 20%-34% of 4.75 mm, 15%-26% of 2.36 mm, 14%-24% of 1.18 mm, 12%-20% of 0.6 mm, 10%-16% of 0.3 mm, 9%-15% of 0.15 mm and 8%-12% of 0.075 mm; according to the present invention, by adjusting the ratio of each grade of the aggregate, the AC material having the noise reduction performance not inferior to the noise reduction performance of the conventional SMA material can be provided, and the noise reduction performance does not violently fluctuate along with the temperature change in the environment with the large day-night temperature difference, and the excellent low-temperature tension resistance can be maintained; therefore, the pavement material can be widely applied to drought regions with less rain and is low in cost.
本发明提出了一种路面材料，包括骨料，骨料包括至少九个级配，至少九个级配根据骨料粒径从大到小依次为，13.2mm为90％‑100％，9.5mm为50％‑75％，4.75mm为20％‑34％，2.36mm为15％‑26％，1.18mm为14％‑24％，0.6mm为12％‑20％，0.3mm为10％‑16％，0.15mm为9％‑15％以及0.075mm为8％‑12％；通过调整骨料各级配的配比，能够提供具有不亚于常规SMA材料降噪性能的AC材料，并能够在昼夜温差较大的环境，使其降噪性能不会随温度变化而发生剧烈的波动并保持优良的低温抗拉能力，从而使该种路面材料能够广泛适用于少雨干旱地区且成本低廉。
