DESIGN PRACTICES FOR PAVED SHOULDERS

This paper presents the results of a study to develop improved methodology for designing paved shoulders adjacent to portland cement concrete pavements. A survey of 1975 shoulder practices was conducted as a part of National Cooperative Highway Research Program Project 14.3. The results indicate that most shoulder pavement sections are underdesigned. Truck traffic encroaching on the shoulder, together with water entering the longitudinal joint, and severe climatic conditions are the most important causes of early shoulder deterioration. A major recommendation is that the shoulder in the vicinity of the joint be structurally designed to withstand the wheel loadings from enroaching truck traffic. Alternate designs are developed for a range of traffic, soil, and environmental conditions by using the American Association of State Highway Officials Interim Guide for Design of Pavement Structures. These structural sections should be supplemented with subsurface drainage or seated longitudinal shoulders based on environmental conditions or subgrade conditions or both. /Author/
