摘要
采用美国SHRP计划动态剪切试验方法,对添加硅藻土的改性沥青的流变性能和相转变进行考察。结果表明:沥青添加硅藻土后,能改善沥青的高温性能;加入硅藻土后,玻璃化温度降低,沥青的相转变界线模糊,改善了沥青的低温性能。
The rheological property and phase-transition of diatomite modified asphalt were invesitaged according to the dynamic shearing experimental method of SHRP. The result showed that the glass temperature was decreased and the phase transferation changed unclear when the diatomite was added into asphalt, so, the high temperature and low temperature properties of asphalt could be improved by diatomite.
