Study on relationships between parameters of low temperature rheological property of asphalt binder
The paper studied the relationships between different low-temperature performance parameters of asphalt binders.After deduction,one physical equation between creep rate and creep stiffness was established and based on this equation,one method used to compare low-temperature performance of materials was also built.Nine kinds of rubberized warm asphalt (RWA) binders were prepared according to orthogonal test design method and the low temperature property indicators were tested.The paper used the test results to verify the correctness of established physical equation and analyzed the correlation between different low-temperature performance parameters.The analysis demonstrated that creep rate and relaxation time,creep rote and dissipation energy ratios,creep rate and stiffness ratio as well as dissipated energy has a good linear correlation,respectively.However,there is no correlation between delay time and other low-temperature performance parameters,and dissipation energy ratio and stiffness.
