Geometric Design of Roundabouts This course presents a summary of the geometric design process for modern roundabouts. Roundabouts are a common form of intersection control used throughout the world and increasingly in the United States. The information supplied in this course and is based on established and emerging U.S. practices and recent research. Selection and…
Design and Construction of Concrete Overlay State Highway Departments and local street and road agencies are currently faced with aging highway systems and a need to extend the life of some of the pavements. Existing design procedures for Portland cement concrete overlays deal primarily with an existing asphaltic concrete pavement with an underlying granular base…
Design of Flexible Pavements This course presents the design of flexible pavements by means of mechanistic empirical methods that are based on the analysis of stresses and strains in the pavement structure due to traffic loads or environmental effects using multi layer theory. It presents the inputs needed to calculate stresses and strains and how…
Sustainable Concrete Pavements This course includes best practices related to concrete pavement design, materials, construction, use/operations, renewal, and recycling. It presents issues specific to pavement sustainability in the urban environment and to the evaluation of pavement sustainability. It presents sustainable design concepts including context-sensitive design, design attributes that directly enhance sustainability, and alternative and emerging…
Pavement Design for Roads, Streets, Walks, and Open Storage Areas This online course provides guidance for design of pavements and supporting materials for roads, streets, walks and open storage areas. The training materials include procedures for conducting preliminary site reconnaissance, traffic analyses, and criteria for the design of subgrade, subbase, base courses, flexible and rigid…
Home Builders Guide to Earthquake Resistant Building Design The purpose of this course is to familiarize the engineer with the basic principles of earthquake-resistant design for residential construction. Adequate construction is required in order for a structure to fair well during and after an earthquake. This course will cover the general earthquake-resistance requirements in the…
