NEW STRUCTURAL SYSTEMS FOR ZERO-MAINTENANCE PAVEMENTS. VOLUME 1 ANALYTICAL AND EXPERIMENTAL STUDIES OF AN ANCHORED PAVEMENT: A CANDIDATE ZERO-MAINTENANCE PAVEMENT

This report documents an investigation of the design feasibility and construction cost-effectiveness of an anchored pavement concept for Zero-Maintenance highways. An analytical model is designed to verify computer program results and to investigate construction methods for a full-scale highway section. The purpose of the analytical study is (1) to present thermal, mechanical, and thermomechanical properties of typical materials in a form easily adaptable to computer programs, and (2) to describe environmental and mechanical properties of a conventional slab and an anchored pavement in both continuous and jointed configurations. The two pavements were subjected to heat transfer, thermal stress, and mechanical stress analyses. The anchored pavement offers two distinct advantages over a conventional pavement-deflections are lower and more uniform, and stresses in the soil are lower and distributed more widely by the rigid anchors. Subgrade-related failure is less likely to occur if loads are transmitted deeper within the subgrade. Three-dimensional finite element analysis is considered to be the most efficient technique for examining the significance of environmentally induced stress. The use of the finite element method is anticipated as more advanced analytic techniques are developed. (FHWA)
