Analysis of N-Layered Viscoelastic Pavement Systems
The primary response model programmed in the VESYS II-M pavement design and analysis structural subsystem provides for the solution of a three-layered viscoelastic pavement system only. This report modifies this primary response model by extending the solution for stresses, strains, and deflections, to an N-Layered Viscoelastic system for any value of Poisson's ratio. An approximate probabilistic solution for the N-Layered viscoelastic system is also presented in closed form. A rut-depth prediction model which uses simplified laboratory characterization tests is developed. The resulting pavement design and analysis models are structured into a set of modular subsystems which provide for easy replacement and incorporation of improved components in any one of the subsystems. An initial concept to optimize the procedure for the design of flexible pavement systems is also presented. The primary response model for the N-Layered pavement system developed in this report has been incorporated into the VESYS II-M computer code. This modified code, known as VESYS G, is presented in PB-282 578.
