摘要
Abstract
Based on the indoor wheel track test, static creep test as well as dynamic creep test, deformation characteristics were studied under the specific conditions of temperature, pressure and so on, and high temperature performance of bituminous mixture was comprehensively evaluated. A proposal was put forward that such indices as dynamic stability, relative deformation, static creep stiffness and dynamic creep stiffness should be used to make a multi-indices evaluation of high temperature performance. Analysis of the correlation between these indicators shows that both dynamic stability and relative deformation of samples of different thicknesses(50,70 mm)present a good linear correlation, and there is also an obvious linear relationship between static stiffness and dynamic stiffness at the temperature of 40 ℃.关键词
