Abstract: This paper describes a statistical approach to estimating an appropriate inspection interval for highway bridges based on historical condition data collected from 20 years of routine inspections. Condition ratings of 4,270 ...

Abstract: This paper explores the characterization of Kevlar composite materials using Raman spectroscopy. The goal of the research is to develop and understand the Raman spectrum of Kevlar materials to provide a foundation for the ...

Abstract: This paper addresses the effect of solar loading on thermal imaging for the detection of subsurface deterioration in concrete bridge components. The deterioration of the concrete resulting from corrosion of embedded mild ...

Abstract: This article reports on research to experimentally analyze the reliability of ground-coupled ground-penetrating radar (GPR) for the detection and imaging of subsurface delamination in concrete. Experimental studies were ...

Abstract: In this study, the ultrasonic time of flight diffraction (TOFD) method to locate and size flaws in steel members was evaluated. This was done by measuring the location and depth of flaws implanted in steel plate specimens ...

Abstract: This paper presents a new methodology for determining bridge inspection intervals and procedures. The methodology was developed using established risk-based methodologies with the goals of improving bridge safety and ...
