摘要
选用3种矿粉和两种沥青,在粉胶比为0.7、1.0、1.3条件下研究沥青胶浆的疲劳性能。结果表明:不同矿粉对沥青胶浆的疲劳性能影响不同,粉胶比的增大会使得沥青胶浆的疲劳性能下降,另外,相同条件下高粘沥青胶浆的疲劳性能好于基质沥青胶浆。
With three kinds of limestone and two kinds of asphalt, this paper studies the fatigue perform- ance of asphalt mortar under the conditions that filler - bitumen ratio is 0. 7, 1.0 and 1.3 respectively. The result indicates that different limestones have different influences on asphalt mortar, and larger filler -bitumen ratio cause degradation on fatigue performance of asphalt mortar. What~ more, the fatigue of high viscosity as- phalt mortar performs better than the matrix asphalt mortar under the same condition.
