提高泡沫沥青冷再生材料性能的方法研究

Study on Method to Improve Cold Recycled Material Performance of Foam Asphalt

对泡沫沥青混合料的强度影响因素进行了分析,研究发泡效果、填料种类、温度及养生时间对泡沫沥青的强度的影响。试验结果表明,通过提高泡沫沥青的膨胀率、选取合理的填料种类、提高拌合时集料温度、适当增加养生时间是提高泡沫沥青混合料强度的行之有效的方法。

The article analyzes the factor to influence the strength of foam asphalt mixture, and studies the influence of foaming effect, stuffing type, temperature and curing time on the strength of foam asphalt. The experimental result shows that it is the effective method to improve the expansion ratio of foam asphalt, to select the reasonable stuffing type, to enhance the aggregate temperature during mixing and properly to increase the curing time for improving the strength of foam asphalt.
