Abstract: Transportation infrastructure condition (or distress) can be modeled as continuous or discrete variables. As discrete variables, they are commonly recorded with nonnegative integers. In deterioration models, these variables ...

Abstract: Diamond grinding (DG) has been used by various districts to improve skid resistance (reduce accidents and fatalities) and improve ride quality [reduce international roughness index (IRI)], with the added benefit of reducing ...

Abstract: This paper investigates an incremental pavement performance model based on experimental data from the American Association of State Highway Officials road test. Structural properties, environmental effects, and traffic ...

Abstract: Both deterioration and policy optimization models play a key role in pavement infrastructure management. A successful management system requires sound deterioration modeling as the basis for the policy optimization modeling ...

Abstract: The evaluation of the effect of maintenance and rehabilitation (M&R) activities plays a critical role in pavement management systems. A quantification of the treatment effect usually resorts to simple statistical regression ...

Abstract: Weigh-in-motion (WIM) technology has found increasing application in the highway and transportation areas for traffic data collection for the purpose of highway capacity analysis, aiding enforcement and, most recently, ...

Abstract: Deterioration modeling is a key component in a transportation infrastructure management system. It serves to capture and predict the performance of a facility. A sound deterioration model should incorporate: (1) relevant ...

Abstract: Deterioration modeling plays a central role in performance prediction, a key component in transportation infrastructure system management. The deterioration of a facility can be expressed in terms of numerous indicators. ...

Abstract: A section of jointed concrete pavement on U.S. 75, which was built from 1982 to 1985, in the Paris District of the Texas Department of Transportation (TxDOT) experienced severe pumping and settlement, even though two types ...

Abstract: A forensic study was conducted to investigate the premature cracking distress on an ongoing construction project on State Highway (SH) 24. Transverse cracks occurred at approximately every 9–15 m (30–50 ft) along the 9.6 km ...
