将硅藻精土掺配在沥青混合料中,可以改善沥青混合料的物理力学性能,提高路面工程的质量。本研究采用室内试验的方法,得出沥青混合料的低温弯曲蠕变速率,对掺加硅藻精土的沥青混合料进行低温性能研究。通过室内试验,证实硅藻精土能够很好地改善沥青混合料的低温性能,并且随着硅藻精土掺量的增加,沥青混合料低温性能的改善程度呈现出一定的规律性。
The diatomite incorporated in asphalt mixture, can improve the physical and mechanical properties of asphalt mixture, improve the quality of pavement engineering. In this study, the indoor test method was used to obtain the low temperature creep creep rate of asphalt mixture, and the low temperature performance of asphalt mixture with diatomite was studied. Through laboratory experiments, it was confirmed that diatomite can improve the low temperature performance of asphalt mixture well, and with the increase of diatomite content, the improvement of low temperature performance of asphalt mixture shows a certain regularity.
