and Canadian agencies, pavement marking warranty specifications now in use represent a blend of methods-based and performance-based thinking. Only three agencies are now using true performance specifications, in which contractors are given full latitude to select pavement marking materials and installation techniques to meet agency requirements for pavement marking performance.

and Canadian pavement marking contractors and two marking materials manufacturers provided private sector perspectives on pavement marking warranties. All interviewed firms believed in providing a quality pavement marking job regardless of whether or not the projects involved a warranty.

, the particular performance measures and ranges of values in minimum acceptable performance thresholds, and varying allocations of risk between agency and contractor. For instance, agencies differ in how they treat winter maintenance damage in their warranties; that is, whether or not they hold contractors responsible for repairing pavement marking damage owing to snowplowing, anti-icing and deicing, studded tires, winter chains, and so forth.

This research could develop more comprehensive knowledge and strengthened analytic techniques in several topic areas; for example, factors affecting the performance of pavement marking materials, the relationship of pavement marking performance to highway mobility and safety, the appropriate distribution of contractor payments through a multi-year warranty period to ensure quality in pavement marking performance while providing fair and timely reimbursement of contractor costs, the potential use of contract incentives to gain superior pavement marking performance beyond warranty requirements, and better quantification of the relative costs and benefits of warranty use. These research findings could help agencies to formulate a more strategic view of warranties; that is, as one method in a range of options to achieve the desired goals of a longer pavement marking life, improve performance during this life, lower life-cycle costs, and reduce the need for road occupancy to repair or replace deficient markings.
