Abstract: This paper investigates the likelihood of occurrence and quantifies the magnitude and rate of discrepancies in highway project final costs with respect to their contract award amounts. Using data from Indiana, we develop ...

Abstract: This study investigates the cost effectiveness of various levels of life-cycle preventive maintenance (PM) for three asphaltic concrete pavement functional class families. For each family, the effectiveness and cost ...

Abstract: Seal coating is a preventive maintenance technique typically applied to low volume asphaltic concrete pavements to defer the need for major rehabilitation. Past research on seal coating effectiveness has generally indicated ...

Abstract: Selecting an appropriate measure of short term maintenance effectiveness and determining its value constitute the first in a three-step process for evaluating maintenance effectiveness in the short term. The second and ...

Abstract: Investment decision making in transportation asset management is typically characterized by a wide diversity of asset types for purposes of optimization at overall system level. To enhance investment analysis and decision ...

Abstract: For the purposes of long-term planning and budgeting, infrastructure user cost allocation, and financial need forecasts, infrastructure agencies seek knowledge of the annual expenditure levels for maintaining their assets. ...

Abstract: This paper determines that microsurfacing can offer average reductions of 0.442 international roughness index (IRI) [in m/km],

Abstract: Civil asset managers continue to seek appropriate thresholds of asset performance for applying standard interventions. Recognizing that between the two extremes of profligacy and parsimony there exists a certain optimal ...

Abstract: At the preconstruction phases of project development, facility stakeholders typically seek reliable estimates of project duration. This paper shows how hazard-based duration models could be used to forecast the actual ...
