THE FINITE DIFFERENCE METHOD IN PAVEMENTS RESEARCH WITH REAL TRANSPORT LOADING

Abstract

The finite differences method application model to calculation of pavements dynamic characteristics is offered. The recurrence relationsallow establishing amplitude-time and am- plitude-frequency characteristics taking into account viscoelastic material properties. Results of computing experiment are received at varied values of physic mechanical characteristics.
