This document contains appendices for the following two documents: NCHRP Report 750, Volume 7: Preservation, Maintenance, and Renewal of Highway Infrastructure and NCHRP Report, Volume 7, Part B, Practitioner's Guide to Emerging Highway Preservation, Maintenance, and Renewal Practices.

Many aspects of design developed by the coastal engineering community are applicable to coastal highway design, planning, and operation. In this manual, many of these concepts and tools are implemented to improve the resiliency of roads and bridges. As exposure to extreme weather events follows its increasing trend, many of these adaptations will become more important to maintaining the coastal highway system.

This report is a compilation of practices for rail maintenance and inspection, including how agencies identify rail defects. Data was collected from literature searches and surveys of heavy- and light-rail transit agencies.

In order to help transportation agencies better understand TPM federal regulations and requirements, USDOT and FHWA have created the video series, "TPM Essentials." The series comprises 18 short clips; each focuses on a specific aspect of federal TPM. The entire series can be found on FHWA's website here or on Youtube here.

"Overview of TPM and HPMS" outlines the key aspects of the relationship between TPM and the Highway Performance System (HPMS). Over the course of this 7.5-minute video, the clip answers the following questions:

• What is TPM?
