摘要
详细介绍了硅藻土的特性和资源分布状况以及其自身的发展状况,并且在公路领域中得到了广泛的应用。硅藻土对于混合料的高温稳定性、低温抗裂性、水稳定性和疲劳寿命有所提高,作为沥青改性剂也有着明显的改善效果,并对硅藻土未来的发展趋势做出了描述和展望。
This paper detailedly introduces the characteristics of diatomite, the distribution of the resources, the development and its widely application in the field of highway. Diatomite can improve the high temperature stability, the low temperature crack resistance, the water stability and the fatigue life of the asphalt mixture. Additionally it has obvious improvement effect as the asphalt modifying agent. Finally, the prospect on the future development trend about diatomite is presented.
