摘要： <正>硅藻精土作为多孔性填料，与沥青作用时有较好的低温性能。通过室内低温劈裂试验及弯曲蠕变试验，以破坏劲度模量、弯曲蠕变速率等主要指标对4种不同沥青混凝土的低温抗裂性能进行了比较。结果表明：硅藻精土可改善沥青混凝土的物理力学性能，是一种非常好的改性剂。
Abstract: As a kind of porous fillers, the diatomite has good low temperature function when added into asphalt. Through cracking and curving experiments on four kinds of different as- phalt concretes, their low temperature function was compared. The result showed that the diatomite was a kind of good modifier. It could improve the physical and dynamic functions of asphalt concrete.
