Contains nine papers that were presented in the eponymously named, ASTM sponsored, conference held in Seattle, Washington, on June 29th, 1999. The papers are divided into treatments of field performance studies, pavement design and drainage, and testing, corresponding to the sessions of the symposium. Topics include cold-climate pavement drainage; performance-based specifications for highway edge drains; and tests of toe drain performance, transmissivity of geosynthetic drains, and clogging behavior.

This report documents the installation of the Hydraway edge drain (version two) on I-64 in Franklin-Woodford-Scott and Fayette Counties. The edge drain was placed on the back side of the trench against the shoulder and backfilled with a sand/slurry. From observations on this project and several previous projects, the sand/slurry backfill helps to insure the integrity of the drainage system during initial backfilling. It is apparent that the sand slurry backfill provides a better installation in comparison to previous methods using excavated trench material. Notable trench settlement did occur on this project. It is apparent that insufficient water was used to properly densify the sand. From observations on other projects, it appears that approximately one gallon per linear foot is required to achieve proper density. It appears that the method of flushing the sand, the speed of the construction, and the amount of water needed to achieve proper density will vary on the contractors equipment and methods. The net result is to achieve proper density without damaging the edge drain. It also appears that the initial asphalt plug is not being properly compacted. The Hydraway panel was reversed to minimize fabric intrusion into the core of the drain. Fabric intrusion into the inner core of the Hydraway drain appeared to be eliminated when the panel was reversed. When the panel was reversed and trench settlement occurred, the rigid back of the panel was forced to bend in the opposite direction it was designed. The net result was cracking occurring in the rigid backing. Information reported in Research Report KTC-91-10, "Evaluation of Headwalls and Outlets for Geocomposite Edge Drains on I-75 and I-71", indicates that 48% of the flexible outlet pipes that were inspected were less than 60% open. Approximately 10% of the rigid outlets inspected during this study were less than 60% open, thus showing a substantial increase in performance. A large amount of distress noted on I-64 was observed in the flexible 4-in. pigtail. If rigid pipe is used throughout the outlet pipe system, performance should increase

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.
