TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 408: Pavement Marking Warranty Specifications presents information on the use of pavement marking warranties by United States and Canadian transportation agencies, including agency specifications. European experience is also included in the report for comparison purposes. Appendices D and E for NCHRP Synthesis 408 are available online--

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 306: Long-Term Pavement Marking Practices documents the current and best practices for managing pavement marking systems, identifies future needs, and addresses driver needs and methods of communicating information to drivers, selection criteria (e.g., reflectivity, pavement service life, wet weather performance), materials (e.g., color, durability, cost), specifications, construction practices, inventory management systems, and more.

This synthesis on the use of warranties in road construction will be of interest to administrators, engineers, designers, and contractors involved with highway design and construction and the procurement process for these services. Experiences with use of warranties in Europe and the United States are cited and the potential impacts, benefits, and concerns of using warranties in the United States are identified. Actions needed to facilitate the use of warranties for highway projects in the United States are also discussed. The use of warranties in road construction is relatively widespread in the European highway industry compared to practice in the United States, where use has been limited. This report of the Transportation Research Board describes the various methods used in Europe for highway industry warranties and identifies the issues that need to be addressed before construction warranties can be translated to U.S. practice. Recent congressional proposals call for the use of warranties to be allowed on federal-aid highway projects. This has caused varied reactions from the parties involved in the design and construction of highways, resulting in a General Accounting Office study on methods for improving the quality of federal-aid highways, including the use of warranties. Ultimately, the owner will have to decide whether to use warranties in highway construction projects. Some of the potential benefits and concerns of using warranties, plus needed actions for successful implementation are presented in this synthesis, which is considered a snapshot of the issues at the time of publication.

Reviews States' experiences with using warranties in highway contracts & the factors that promote or discourage the use of such warranties, identify efforts to provide adequate maintenance for federal-aid highways, & identify opportunities for improving states' procedures for selecting pavement designs. 5 charts & tables.

TRB’s National Cooperative Highway Research Program (NCHRP) Report 699: Guidelines for the Use of Pavement Warranties on Highway Construction Projects is designed to help guide state departments of transportation (DOTs) in establishing pavement warranty programs.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 759: Effective Removal of Pavement Markings aids in the selection of safe, cost-effective, and environmentally acceptable practices for the removal of work zone and permanent pavement markings. The practices highlighted in this report emphasize minimal damage to the underlying pavement or visible character of the surface course." -- Publisher's description
