Abstract: The effectiveness of pavement overlays and pavement replacements in terms of their impact on pavement life is not well understood. This is complicated further by data collection limitations and by the effect that physical ...

Abstract: Highway agencies seek the participation of the private sector in pavement preservation, to raise revenue, share risks, and reduce project delivery costs. With public-private partnerships (PPP) representing an increasingly ...

Abstract: Pavement rehabilitation is one of the most critical and costly forms of infrastructure asset management. Yet determining the subsequent performance of rehabilitated pavements is a complex task, particularly when multiple ...

Abstract: Delays in the completion of highway construction and maintenance projects are important concerns to state highway agencies and contractors alike because such time delays can have a number of adverse consequences, such as ...

Abstract: Transportation agencies worldwide have been preparing themselves to face the growing demand for transportation infrastructure by forming public-private partnerships (PPP), contractual agreements formed between public and ...

Abstract: This study uses aggregate state-level data from 1999 to 2006 in the United States to examine the relationships among pavement performance (pavement roughness) and preservation expenditure, dominant surface geology, and ...

Abstract: Highway agencies around the world are undergoing major changes in their traditional maintenance practices, including the privatization of entire sections of highway routine maintenance activities. Performance-based contracts ...

Abstract: The selection of appropriate type of contract for a highway maintenance project can be influenced by project attributes such as the expected cost and duration. However, the expected project cost and planned duration depend ...

Abstract: This paper focuses on identifying important factors that determine activity-based travel distance in urban areas. Building on past research that has demonstrated the conceptual equivalence of hazard models applied to either ...

Abstract: Construction cost overrun and time overrun (delay) are a significant problem in highway-construction project delivery. Previous research studies have provided insight into the factors that affect overruns; however the ...
