Pavement Engineering will cover the entire range of pavement construction, from soil preparation to structural design and life-cycle costing and analysis. It will link the concepts of mix and structural design, while also placing emphasis on pavement evaluation and rehabilitation techniques. State-of-the-art content will introduce the latest concepts and techniques, including ground-penetrating radar and seismic testing. This new edition will be fully updated, and add a new chapter on systems approaches to pavement engineering, with an emphasis on sustainability, as well as all new downloadable models and simulations.

SUMMARY This book provides complete coverage of surface and subsurface drainage of all types of pavements for highways, urban roads, parking lots, airports, and container terminals. It provides up-to-date information on the principles and technologies for designing and building drainage systems and examines numerous issues, including maintenance and designing for flood events. Practical considerations and sophisticated analysis, such the use of the finite element method and unsaturated soil mechanics, anisotropy and uncertainties, are presented. This book allows civil engineers to make the best use of their resources to provide cost effective and sustainable pavements. Features Presents a holistic consideration of drainage with respect to pavement performance. Includes numerous practical case studies. Examines flooding and the impacts of climate change. Includes PowerPoint slides which include quizzes, schematics, figures, and tables.

This report describes the development of a complete pavement system which incorporates an open graded drainage layer to effectively remove infiltrated water. Candidate materials for use as open graded drainage layers were investigated using laboratory studies of flow characteristics and loading studies to measure accumulated deformations. The research team found that the required hydraulic conductivity of an open graded drainage layer must exceed 1,000 fpd for typical interstate design. For extreme conditions, hydraulic conductivity requirements may approach 5,000 fpd. Two standard Illinois DOT aggregate gradations, CA-7 and CA-11, were found to have hydraulic conductivities in excess of 5,000 fpd. Stability tests conducted on the open graded drainage layers indicate that stabilization with PCC cement or asphalt cement would be required if the materials were to be trafficked prior to final paving. Minimum PCC cement contents of 6% by weight of aggregate are required for adequate stabilization. Minimum asphalt cement contents of 2.5% are required. Observations of open graded drainage layer construction projects were made to document the practicality of construction. These observations indicate open graded drainage layers may be successfully placed if construction equipment specially suited to these materials is used.
