基于CAM模型的沥青混合料粘弹性能研究
Study on viscoelastic performance of asphalt mixture based on CAM model
摘要
Abstract
In order to study the viscoelastic characteristics of asphalt mixtures in the whole-frequency range, a dynamic shearing rheometer is used to carry out dynamic frequency sweeps for asphalt mixtures, which obtains the three-dimensional relationships among G*, temperature and frequency. Then the time-temperature shift principle is used to translate the relationships from three dimensions to two dimensions, so master curves are obtained regarding dynamic modules changing along with the frequency over 15 amount levels. The Christensen-Anderson-Marasteanu (CAM) model, a kind of the theological model, is used to analyze and compare theological performances of several asphalt mixtures based on the obtained master curves. The results indicate that the dynamic rheological test is an effective method for obtaining the master curve. Besides, the CAM model can describe well the viscoelastic deformation characteristics of asphalt mixtures.关键词
