Laboratory Determination of Burger's Model Parameters for Visco-elastic Analysis of Road Pavement Materials
Abstrakt
Burger's Model is one of those models that describes performance of asphalt mixtures. Its parameters can be used in road construction analysis based on visco-elastic properties in wide variety of temperatures using dedicated programs (e.g. Veroad) or in Finite Element Method (FEM). Parameters of Burger's Model can be used for example in prediction of low temperature cracking in low winter temperatures or permanent deformation in high summer temperatures. This paper presents method of determination of Burger's Model parameters for low and high temperature viscoelastic analysis. Laboratory tests were conducted to determine performance of asphalt mixtures: for low-temperature behavior - beam creep test and for high-temperature - core creep test. Mathematical approximation of test results for specific parameters of Burger's Model was made. Several variations of approximation method were prepared to determine of each rheological parameter . As a conclusion comparison of theoretical curve calculated with various approximated parameters of Burger's Model and creep curve obtained from laboratory tests is presented.
