Book Description
This document contains two appendices to NCHRP Report 597, "Development of a Recommended Practice for Use of Controlled Low-Strength Material in Highway Construction." Appendix A, Corrosion Study, examines the corrosivity of controlled low-strength material (CLSM) on pipelines embedded in it. Appendix E, Implementation Plan, describes several issues and recommended next steps that can help to insure the successful use of the guidance and technology developed under this project.

Book Description
Explores the use of controlled low-strength material (CLSM) in highway construction applications, in particular, as backfill, utility bedding, and void fill and in bridge approaches. The report also examines a recommended practice for the use of CLSM that was developed through a series of full-scale field experiments. This report presents the full text of the contractor's final report of the project and three of the five appendices, which present the test methods (Appendix B), specifications (Appendix C), and practice (Appendix D) recommended for implementation. The corrosion study (Appendix A) and implementation plan (Appendix E) are available online as NCHRP Web-Only Document 116.

Book Description
Ductile iron pipe (DIP) was introduced about 50 years ago as a more economical and better-performing product for water transmission and distribution. As with iron or steel pipes, DIP is subject to corrosion, the rate of which depends on the environment in which the pipe is placed. Corrosion mitigation protocols are employed to slow the corrosion process to an acceptable rate for the application. When to use corrosion mitigation systems, and which system, depends on the corrosivity of the soils in which the pipeline is buried. The Bureau of Reclamation's specification for DIP in highly corrosive soil has been contested by some as an overly stringent requirement, necessitating the pipe to be modified from its as-manufactured state and thereby adding unnecessary cost to a pipeline system. This book evaluates the specifications in question and presents findings and recommendations. Specifically, the authoring committee answers the following questions: Does polyethylene encasement with cathodic protection work on ductile iron pipe installed in highly corrosive soils? Will polyethylene encasement and cathodic protection reliably provide a minimum service life of 50 years? What possible alternative corrosion mitigation methods for DIP would provide a service life of 50 years?

Book Description
This report contains the findings of research performed to develop a recommended load and resistance factor design (LRFD) specification for thermoplastic pipe used in culverts and drainage systems for highway structures. The report details the research performed and includes a recommended LRFD design specification, a quality assurance specification for manufactured thermoplastic pipe, and the results of supporting analyses.
