and Canadian provincial/ territorial road agencies, with further comparisons to European practice. Pavement markings play an important role in reducing congestion and improving safety by providing information, guidance, and warnings to road users, whether drivers of motorized vehicles, bicyclists, or pedestrians.

Good techniques and products that are available today can readily achieve longer, higher-performance service lives; for example, use of recessed markings in Northern climates; high-quality, durable marking materials; correct placement and application of materials (e.g., glass beads in paint)

EUROPEAN WARRANTY EXPERIENCE The review of European warranty practice was based on recent international scans of highway agencies that were sponsored by the FHWA and AASHTO, and a review of other literature.

• To consider ways to accelerate identification, evaluation, approval, and acceptance of new products, and to incorporate these products within project specifications. The example of a European turntable for accelerated testing of pavement marking materials was the focus of one such recommendation.

raises several questions on how the United States might proceed in pursuing accelerated testing of pavement marking materials and product approvals, building on European experience with test turntables. Research to address these questions could determine whether an accelerated test facility is needed and is feasible, the role of the National Transportation Product Evaluation Program in relation to such a facility, and a recommended strategy, if warranted, to develop such a facility and an agency-acceptable capability for product approvals.
