Performance-Based Pavement Warranty Practices

This synthesis documents practices within state departments of transportation (DOTs) associated with the use of performance-based pavement warranties. The study focuses on asphalt and concrete pavement types, for new construction, preservation, and rehabilitation projects, with warranty periods of at least one year. Information for this study was gathered through a literature review, a survey of state DOTs and Canadian provincial transportation agencies, and follow-up interviews with selected agencies. Five case examples provide additional information on pavement warranty practices. Of the 50 responding agencies to the survey, 32 indicated previously using pavement warranties; however, of these agencies, only 18 indicated that warranties are currently being used in pavement construction. For those agencies that have not considered or no longer use pavement warranties, the primary reasons limiting use was the need for consistent monitoring of pavement distress, concern with cost-effectiveness, and impact to contractor bonding capacity. For the 18 agencies who indicated current pavement warranty use, the main objectives of warranty implementation included increasing quality and shifting more risk to the contractor. Projects selected for pavement warranties are often based on treatment type (new or reconstruction, rehabilitation, and preservation), existing pavement condition for preservation and rehabilitation projects, site conditions, and traffic volumes. During the development of pavement performance criteria, agencies primarily based criteria on pavement management data and engineering judgment. During the design and construction phases, most agencies indicated the contractor is responsible for mix design, and to a lesser extent, pavement thickness design and pavement or treatment type selection. These 18 agencies also indicated pavement warranties provided benefits related to transferring risk to the contractor, reducing pavement failures, improving contractor workmanship, and improving pavement performance. Conversely, agencies indicated several implementation challenges including condition assessment, industry resistance, and defining threshold values.
