一种基于动态剪切流变试验的集料-胶浆弱边界层性能测试方法

一种基于动态剪切流变试验的集料-胶浆弱边界层性能测试方法，本发明涉及一种路面材料性能测试方法。解决现有沥青混合料多尺度力学特性研究中缺少对集料-胶浆界面弱边界层性能表征的问题。方法：首先将粘有岩石基板的上基板及粘有岩石基板的下基板安装在动态剪切流变仪内，然后将试验环境仓温度升温，再将胶浆试件置于流变仪下基板的岩石基板上，将胶浆试件厚度压缩至L，试验测试胶浆试件的动态剪切复数模量G，测试其他待测胶浆厚度L的动态剪切复数模量G，通过L～L、G～G计算各L/G比值，绘制L/G-L曲线图，并按照公式进行非线性拟合，然后得到岩石集料-胶浆弱边界层性能表征参数α、A。 The invention discloses an aggregate-adhesive cement weak boundary layer performance test method based on a dynamic shear rheological test, relates to a pavement material performance test method, andsolves the problem that existing asphalt mixture multi-scale mechanical property research lacks of performance characterization of an aggregate-adhesive cement weak boundary layer. The method comprises the following steps: first, mounting an upper substrate which is adhered with a rock substrate and a lower substrate which is adhered with another rock substrate in a dynamic shear rheometer; then,rising the temperature of a test environment bin, and placing an adhesive cement test piece on the rock substrate of the lower substrate of the
