制备工艺对高黏改性沥青性能的影响研究
Research on Influence of Preparation Process on the Properties of High Viscosity Modified Asphalt
摘要
Abstract
The rubber/resin composite modifier SGCY and Qilu AH-70 asphalt were used as raw materials to prepare high vis-cosity modified asphalt with different shearing process and mixing process.The influence of process parameters on the proper-ties of high viscosity modified asphalt was investigated,the results show that the preparation process parameters have less influ-ence on the conventional indicators of high viscosity modified asphalt,but more influence on the viscosity and storage stability.The dynamic viscosity,workability and storage stability of high viscosity modified asphalt can be enhanced by increasing the preparation temperature or extending the preparation time.Moreover,the preparation time can be reduced by increasing the preparation temperature.Compared with the swelling and dispersion process,the crosslinking and development process con-tributes more to the improvement of storage stability for high viscosity modified asphalt.Two preparation processes of high vis-cosity modified asphalt are developed and optimized for SGCY modifier,i.e.shear process and mixing process.关键词
