Abstract

The paper focuses on providing details on the application of a continuum-based finite-layer model to estimate ground-borne vibrations induced by moving trucks. The computational model incorporates important pavement response factors such as the noncircular contact area, complex 3-D contact stress distributions (normal and shear), vehicle speed, and viscoelastic material characterization. The proposed method is much more computationally efficient than the moving-load models based on the finite element method. Predictive capability of the approach relative to vehicle-induced vibrations has been demonstrated using realistic pavement loading. As an important design application, particle velocity responses from conventional dual and its recent substitute, viz. wide-base (super-single) tires have been computed and compared.

Estimation of Ground-Borne Vibrations from Moving Trucks

San Diego, California
