This report is a six-volume series describing laboratory experiments conducted at Colorado State University for FHWA as part of a study on "Effects of Sediment Gradation and Cohesion on Bridge Scour." Volume 1 describes the effects of sediment gradation and coarse material fraction on local clear water pier scour. Volume 2 describes the effects of sediment gradation and flow hydrographs on local clear water pier scour. Volume 3 describes the effects of sediment gradation and coarse material fraction on local abutment scour. Volume 4 describes the effects of cohesive soils on local pier scour. Volume 5 describes the effects of cohesion on local abutment scour. Volume 6 describes the effects of stratified sand layers on local abutment scour.

A synthesis report -- FHWA-RD-99-189, "Bridge Scour in Nonuniform Sediment Mixtures and Cohesive Materials: Synthesis Report" -- that condenses information from each of the six volumes is being prepared for publication in December 2000.

Materials and Procedures for Repair of Potholes in Asphalt-Surfaced Pavements - Manual of Practice
Publication No. FHWA-RD-99-168

This Manual of Practice is an updated version of the 1993 Strategic Highway Research Program (SHRP) Pothole Repair Manual. It contains the latest information pertaining to the types and performance characteristics of repair materials and methods, as well as the proper ways of planning, designing, constructing, and monitoring the performance of pothole repair projects. It also details how the cost-effectiveness of pothole patch types can be determined, and it provides an updated partial listing of material and equipment manufacturers.

The manual is intended for field and office personnel within highway maintenance agencies and contracted maintenance firms. It contains valuable information for supervisors and forepersons in charge of individual patching operations, engineers in charge of planning and overseeing many patching projects, and managers in charge of establishing pothole repair policies and standards.

An Introduction to the Deep Soil Mixing Methods as Used in Geotechnical Applications Volume I: Final Report
Publication No. FHWA-RD-99-138

The Deep Mixing Method (DMM) is an in situ soil treatment technology whereby the soil is blended with cementitious and/or other materials. This report first traces the historical development of the various propriety DMM methods and provides a structured summary of applications. It also compares the applicability of DMM with other competitive forms of ground treatment and improvement. The bulk of the report constitutes a description of the individual methods, focusing on the equipment, the procedures, and the properties of the treated soil. The report continues by describing the nature of the market in North America, Japan, and Scandinavia, while observations are also made on the various potential barriers to further growth in the United States. This report incorporates some factual data from an earlier FHWA draft report (1996), but follows a different structure and philosophy.

This volume is the first in a series. The other volumes in the series are FHWA-RD-99-144, Volume II: Appendices, and FHWA-RD-99-167, Volume III: The Verification and Properties of Treated Ground.

Insights Into Pavement Preservation
Publication No. FHWA-IF-00-011

The challenge facing highway agencies today is to preserve a system on which so much importance -- from the national economy to individual lifestyles -- routinely depends. This shift of emphasis from building and improvement to maintenance and preservation requires both a national scope and a local sense of purpose. This booklet's focus -- pavement preservation -- is just one aspect of a complex endeavor in which the broad range of organizations comprising the highway community is cooperating. One of the aims of this publication is to make clear what pavement preservation is -- and what it is not.

This compendium is meant to provide a short, nontechnical survey of recent articles on pavement preservation for use by members of the highway community -- as well as the general public -- who have an interest in this important topic, but not necessarily a technician's background. FHWA is publishing this as part of its mission to provide tools and concepts useful to those who maintain and preserve our National Highway System.
