Abstract

Abstract: The performance and rheological properties of modified asphalt mortar with diatomite are studied by way of conventional tests and the Strategic Highway Research Program (SARP)tests such as the Dynamic Shear Rheometer (DSR) test and the Bending Beam Rheometer (BBR) test.The contrast is made between conventional tests and SHRP tests. It is shown that the diatomite improves the high temperature properties and anti-aging properties of asphalt mortar greatly,and conventional tests can’t evaluate the

Key words: asphalt mortar, rheological properties, diatomite

摘要： 通过常规试验和美国SHRP的动态剪切流变试验、弯曲梁蠕变试验,研究硅藻土改性沥青胶浆的技术性能和流变特性,并将常规试验和SHRP试验结果进行对比分析,结果表明:硅藻土可以大大改善沥青胶浆的高温稳定性和抗老化性能,常规试验不能很好地评价硅藻土改性沥青胶浆的技术性能
