The research developed 3-dimensional heavy vehicle models to evaluate the dynamic loading on pavements using measured road roughnesses. Two truck configurations: 2-axle straight trucks and 5-axle tractor semi-trailers were used in the study. Equations of motion with Coulomb friction were formulated using separated-form virtual work principle. User-friendly computer programs were developed on a PC, which include three portions: nonlinear integration, statistical analysis and graphics. Runge-Kutta-Fehlberg's 4-5th order algorithms (RKF45) with self-adjustable step sizes was adopted to solve the nonlinear differential equations. Numerical and graphical outputs can be provided in both time domain and statistical forms.
