Abstract: The purpose of this paper is to present a new mechanistic-empirical (M-E) rutting model developed for hot-mix asphalt (HMA) overlay thickness design and analysis. After reviewing existing rutting models in the literature, ...

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 ...

Abstract: In laboratory testing of asphalt mixtures, the relationship between the number of load repetitions and permanent deformation has been found to include three distinct stages, namely the primary, secondary and tertiary stages. ...

Abstract: Previous studies on connected autonomous vehicles (CAVs) examined pavement performance and lane widths separately and in isolation, and without consideration for roadworks conditions. Hence, this study presents a holistic, ...

Abstract: Asphalt pavement rutting is caused primarily by shear stresses induced by heavy truckloads. Many tests have been developed to determine asphalt mix rutting potential. However, due to limited correlation with field rutting ...

Abstract: The current performance grade (PG) binder specification uses the parameter

Abstract: Under the same applied traffic loading, time is traditionally assumed to be a function of only the vehicle speed and the depth beneath the pavement surface. Additionally, no definite loading waveform has been established ...

Abstract: Traffic loading is one of the key factors considered in pavement design. It is anticipated that the use of axle load spectra provides more accurate traffic-loading inputs than the traditional equivalent single-axle load ...

Abstract: Asphalt emulsions and cutbacks are mainly used for surface preservation treatments and as bonding layer during pavement construction. Cutback and emulsion residues are routinely evaluated to ensure specification compliance ...

Abstract: The Specific Pavement Study–1 pavement test section on US281 in south Texas comprise the largest Strategic Highway Research Program experimental site in the United States. The project was opened to traffic in 1997, and ...
