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 book presents selected papers from the International Symposium on Geotechnics for Transportation Infrastructure (ISGTI 2018). The research papers cover geotechnical interventions for the diverse fields of policy formulation, design, implementation, operation and management of the different modes of travel, namely road, air, rail and waterways. This book will be of interest to academic and industry researchers working in transportation geotechnics, as also to practicing engineers, policy makers, and civil agencies.

NCHRP Report 583 explores the effects of subsurface drainage features on pavement performance through a program of inspection and testing of the subsurface drainage features present in the Long-Term Pavement Performance SPS-1 (flexible hot-mix asphalt pavement) and SPS-2 (rigid portland cement concrete pavement) field sections.

This research study focused on positive drainage of pavement structures. The open-graded base course concepts included non-stabilized, asphalt cement concrete (AC) stabilized and portland cement concrete (PCC) stabilized. Drainage systems included pipe in trenches, fin-type, pipe beneath transverse joints and retrofitted pipe. Non-drainage elements included 3.05 m (14 ft) wide driving lanes, and a 30.48 cm (12 in.) layer of "select embankment". Twelve projects were monitored, both portland cement concrete surface and asphaltic concrete surface. Measurement surveys included Pavement Distress Index (PDI), transverse joint faulting, International Roughness Index (IRI) ride quality, and coring at the transverse joints.

This synthesis will be of interest to geologists; hydrologists; geotechnical, pavement, construction, and maintenance engineers; and researchers. State department of transportation (DOT) program managers and administrators will also find it of interest. The synthesis describes the current state of the practice for the design, construction, and maintenance of pavement subsurface drainage systems. It provides information on the positive effects of good subsurface drainage and the negative effects of poor subsurface drainage on pavement surfaces. This report of the Transportation Research Board presents data obtained from a review of the literature and a survey of the state DOTs. It is a supplemental update to NCHRP Synthesis of Highway Practice 96, Pavement Subsurface Drainage Systems (1982). The synthesis provides a supplement to design issues not found in Synthesis 96, but faced by current designers, e.g., type and quality of aggregate, compaction requirements for open-graded aggregates, asphalt and cement binders, and use of geosynthetics. In addition, it describes the effects of design, construction, and maintenance decisions on the performance of pavement subsurface drainage systems.

This study was aimed at evaluating the performance of pavement drainage systems that can be used in the State of Illinois using locally available aggregate sources for construction of these drainage systems. The study was limited to investigations on the use of open-graded, hot-mixed bituminous aggregate mixtures (OGBAM), for use in the pavement drainage system. A preliminary investigation was carried out in the laboratory to evaluate the permeability and the stability of the OGBAM. Specimens were prepared according to the procedures given by ASTM D 1559, Resistance to Plastic Flow of Bituminous Mixtures Using Marshall Apparatus. Permeability test (using a constant-head permeameter that allowed the measurement of permeability at low heads) and stability test were performed on the same specimen. Using the results of the preliminary investigations, six test pavements (4 feet long) incorporating different design concepts were tested in the University of Illinois Test Track. Dynamic loading was applied to the test pavements and water was passed through the OGBAM drainage layers to simulate surface and lateral infiltration. Permeability tests at constant head were carried out regularly on the pavement test sections. The progress of rutting in the test pavements was also recorded. Results of these limited tests indicate that OGBAM possess a very high order of permeability, and that care must be taken to prevent the migration of subgrade fines into the OGBAM layers for satisfactory performance of OGBAM layers with regards to drainage. The report outlines some of the methods that can be used to ensure satisfactory performance of pavements using OGBAM layers.
