| 摘要： | This synthesis study updates information on the use of pavement marking warranties by U.S. state departments of transportation (DOTs) and Canadian provincial/territorial transportation agencies. It also reviews road construction warranty experience in Europe for comparison. Pavement markings provide information, guidance, and warnings to road users. Interest in applying warranty specifications to pavement markings is driven by their importance to traffic mobility and safety, and the resulting desire for better pavement marking performance, greater cost-effectiveness, and other potential benefits. Data for this synthesis were obtained from a literature review, a survey of U.S. and Canadian transportation agencies, and interviews with U.S. and Canadian pavement marking contractors and materials manufacturers. Forty state DOTs and eight Canadian transportation agencies responded to the synthesis survey. Respondents were divided almost equally between those that now use pavement marking warranties (23 agencies, or 48% of the survey population) and those that do not (25 agencies, or 52%). Fifteen of the 23 agencies that now use pavement marking warranties provided one or more examples of current specifications, which are compiled in Appendix D (provided as a web-only portion of the report) and are a rich source of information on the various approaches and specific contract provisions now in use. |
