一种路用草本植物纤维沥青混合料及其制备方法
摘要：
本发明公开了一种路用草本植物纤维沥青混合料及其制备方法。这种路用草本植物纤维沥青混合料由六种组分制成，各组分重量百分数为：草本植物改性纤维0.2%-1%、沥青5%-9%、粗石子38%-43%、细石子28%-33%、粗石粉8%-12%、细石粉5%-8%。其制备方法包括草本植物纤维的制备与改性、石料分选与配制、油石热混与铺设三个步骤。采用本发明制备的路用草本植物纤维沥青混合料特别适合于城乡快速路、主干路的铺设，并使道路的高温稳定性、低温抗裂性能和水稳定性得到明显改善。
摘要（英）：

The invention discloses a herbaceous plant fiber and asphalt mixture for a road and a preparation method of the herbaceous plant fiber and asphalt mixture. The herbaceous plant fiber and asphalt mixture for the road is prepared from six components in percentage by weight: 0.2%-1% of herbaceous plant modified fiber, 5%-9% of asphalt, 38%-43% of coarse stone, 28%-33% of fine stone, 8%-12% of coarsestone powder and 5%-8% of fine stone powder. The preparation method comprises the three steps: preparation and modification of herbaceous plant fiber, stone separation and preparation as well as heatmixing and paving of oil stone. The herbaceous plant fiber and asphalt mixture for the road, which is prepared by using the preparation method, is particularly suitable for paving urban and rural expressways as well as major roads and capable of remarkably improving the high-temperature stability, low-temperature crack resistance and water stability of the road.
