摘要：	As the primary focus of the Virginia Department of Transportation (VDOT) changes from highway construction to transportation maintenance, there is an increased need to extend the value derived from limited funding resources by increasing the service life of pavement rehabilitation treatments. In this regard, the development of a pavement warranty contract and a performance specification was considered in an effort to ensure that VDOT continues to deliver the highest quality pavement to the traveling public. In an effort to help increase the overall quality of the roadway network and thus increase the service life of pavement resurfacings, VDOT sought to investigate the use of a warranty clause as part of an upcoming resurfacing contract. A performance-based warranty clause was developed in this pilot study to be included as part of the contract documents for a typical interstate resurfacing project. In this process, the bidding contractors would be given information about the condition of the pavement obtained from data collected through cores and the falling weight deflectometer and then the contractor would be responsible for developing the resurfacing pavement design that fulfilled the conditions of the warranty clause. The review of the submitted bids would be conducted in two stages where the technical merit of a proposal would be evaluated prior to the opening of a cost estimate.
