硅藻土改性沥青路面抗车辙性能研究

硅藻土是一种是由古代生物硅藻遗骸沉积形成的一种化石性硅藻堆积土矿床。研究表明,硅藻土作为改性材料添加到沥青混合料当中,对提高沥青混合料的高温抗车辙性能提高较大。吉林省在硅藻土改性沥青混合料的推广应用方面具有很多成功的经验,通过实体工程调查和检验,硅藻土改性沥青路面的高温抗车辙性能同对比路段相比均有所提高。

diatomite is a is by ancient biological diatom remains deposition Research shows that, as modified materials added to diatomite of asphalt anti--rutting greater performance. In jilin province diatomite modified the many successful experience, through the engineering investigation pavement of high temperature anti--rutting performance compared with Key Words： DiatomiteIAsphait ~Sleeper-type of resistance of the formation of a fossil diatoms of deposit soil deposits. mixture, to improve the asphalt mixture of high temperature asphalt mixture with the popularization and application of and inspection entity, diatomite modification of the asphalt comparative sections are improved.
