From page 1...
... State DOTs have gained considerable warranty experience, with varying results, since the Federal Highway Administration lifted its prohibition against the use of construction warranties in 1995. This research report summarizes current pavement warranty practices based on a review of the literature, DOT interviews, a joint industry/DOT workshop, and a review of internal DOT procedures and specifications collected as part of the research.
From page 2...
... If the risks are high for a given warranty type, the tool suggests strategies to mitigate risk by modifying the scope of the project or the warranty or choosing the warranty type that fits with the level of control or responsibility allocated to the contractor under the contract, the accuracy of the traffic projections, or historic pavement performance data for the pavement type. • Comprehensive warranty guidelines are necessary to assist DOTs in implementing the appropriate warranty type for the specific project or program objectives, allocating risk, and addressing what elements are important to consider when drafting a warranty specification for hot mix asphalt (HMA)
