Abstract: Warranties have been used by many highway agencies in response to increased demand for including quality concepts in all phases of the highway life cycle and to guard against premature infrastructure failures. Currently, ...

Abstract: Current materials and construction specifications for pavement preservation treatments are predominantly prescriptive and rarely correlate the initial quality of the treatment to its future performance. As a result, it is ...

Abstract: The risk in multiyear asset management plans for pavement networks stems from uncertainties in inputs to these plans. Although the literature is rich in probabilistic models and procedures for individual components of asset ...

Abstract: Transportation agencies around the world are using contractor-performed test results in construction and material acceptance and pay decisions. This practice is termed contractor acceptance testing (CAT) in this paper. ...

Abstract: Pavement condition indexes are numerical indicators of the structural and material integrity of a pavement. Because these indexes appear to be similar (essentially a 0–100 scale, with 100 indicating ideal condition), it ...

Abstract: With the increasing number of aging bridges that need maintenance and rehabilitation (M&R), it is important to plan and prioritize M&R projects proactively. This process requires mathematical models capable of ...

Abstract: One of the main activities in transportation infrastructure asset management is the allocation of available funds across infrastructure classes (e.g., pavements, bridges, signs) or programs (e.g., maintenance, construction). ...

Abstract: A prototype methodology for integrating highway infrastructure management activities has been developed. This paper describes the analytical procedures and data integration and presentation methods as well as the geographic ...
