Review of Research Progress of High Viscosity Modified Asphalt
摘要
Abstract
With the promotion of sponge city idea and the in-depth development of high-grade highway construction,drainage asphalt pavement has been widely used in China.As the core cementing material of drainage asphalt pave-ment,the performance of high viscosity modified asphalt directly determines the long-term service ability and dura-bility of the pavement.Systematic research and optimization of its performance has become a key technical topic in the field of road engineering.The research progress of high viscosity modified asphalt was systematically reviewed,focusing on the research status of its typical formulation system,preparation process and macro and micro proper-ties.The aging behavior and characterization methods of high viscosity modified asphalt under different aging condi-tions,such as thermal oxygen,UV and moisture heat coupling,were introduced.There are still some deficiencies in the current research:The interaction mechanism of multi modifier is not clear,lacking of the systematic theoretical guidance of"formula-process-performance-microstructure";The research on performance evolution law and aging micro mechanism under complex environment is not deep enough.Based on this,it should focus on the multi-scale disclosure of the composite modification mechanism and the precise regulation of the formulation process in future,establish a standardized preparation and performance evaluation system,carry out multi factor coupling aging test and cross-scale simulation,and improve the aging evaluation model of macro and micro integration,so as to provide support for the theoretical improvement and engineering application of high viscosity modified asphalt.关键词
