Abstract: In this paper, we evaluate the performance of a spatial multiresolution analysis (SMA) method, that behaves like a variable bandwidth kernel density estimation (KDE) method, for hazardous road segments identification (HRSI) ...

Abstract: Weak joints are the source of most performance problems in jointed concrete pavements (JPCPs) and composite pavements created by overlaying a JPCP. Until recently, it has been prohibitively time-consuming to evaluate the ...

Abstract: The safety of a pavement surface can be characterized by properties such as skid resistance and texture. All pavement surfaces should be constructed and maintained such that they meet the friction demand of the roadway. ...

Abstract: The structural capacity of a pavement has been shown to be an excellent indicator of the required maintenance and expected performance of asphalt pavements, but studies reported in the literature have produced few indices ...

Abstract: Optimization-based tools have been included in many engineering management systems for individual infrastructure asset classes such as pavement management systems (PMS) and bridge management systems (BMS). These tools ...

Abstract: Researchers have studied the vulnerability of roadway systems to disasters, such as terrorist attacks or natural disasters. However, the literature has not explicitly addressed other factors, such as infrastructure condition, ...

Abstract: In this paper, the difference sequence method is used to decompose traffic speed deflectometer (TSD) deflection slope measurements variability into “true” spatial variability that is due to pavement structural changes and ...

Abstract: This paper presents a network-level structural capacity indicator for asphalt pavements in the state of Virginia. A literature review revealed that several network-level structural capacity indexes have been proposed, and ...
