Experimental Study on Static and Dynamic Compressive Resilient Modulus
To study the effect law of asphalt mixture composition design and static–dynamic test methods on resilient modulus, and consummate the design parameters of asphalt mixture, the laboratory tests on static–dynamic compression resilient moduli and strength are conducted by the uniaxial unconfined method and top measuring method by MTS-810. The result shows that (1) there is no direct relationship between strength and resilient modulus of asphalt mixture; and (2) both the aggregate gradation and asphalt quality can influence the value of resilient modulus, and the influence from asphalt quality is more significant. By studying the deformation law of the material under static and dynamic loading throughout the test, and combining with the Kelvin mechanical model and viscoelastic theory of asphalt mixture, the limitations of the static and dynamic moduli are demonstrated. It shows that the viscoelastic property is the important factor affecting the values of static and dynamic moduli of the mixture, and resulting in smaller values of moduli. In the end, the linear relationship between static and dynamic moduli is researched, and the conversation equation of static and dynamic moduli for different nominal maximum aggregate sized mixture is obtained, which is more accurate compared to the existing formula.
