摘要
采用120-180℃老化试验，研究沥青、二水和β型半水硫酸钙晶须以及二者改性的沥青在不同时间的累积质量损失，发现硫酸钙晶须与沥青在高温环境中相互牵制，抑制了彼此的衰减，为硫酸钙晶须应用于沥青路面提供了热力学行为基础。
Employing the method of aging test from 120℃ to 180℃, asphalt, calcium sulfate whisker including two water molecules, the accumulative mass losses of Q-calcium sulfate whisker including half water molecule and asphalt modified by calcium sulfate whisker or Q-calcium sulfate whisker with the time development were researched. It could be found that calcium sulfate whisker and asphalt interlink with each other, so the decay phenomena of them are supressed. The findings offer foundations of thermodynamic behavior for application of the calcium sulfate whisker in asphalt pavement.
