Abstract: Fourier transform infrared spectroscopy by attenuated total reflectance (FTIR-ATR) has been applied to laboratory studies of bitumen rejuvenator diffusion. Previous studies have given more indications rather than a real ...

Abstract: Three styrene–butadiene–styrene coblock polymer modified asphalt concrete mixtures (70/100M5, 160/220M5, and 160/220M10) are characterized using complex modulus and fatigue testing. The compositions of the materials ...

Abstract: Current knowledge on material-related aspects of asphalt recycling with focus on findings from fundamental studies is summarized. By way of introduction, a general description of different types of asphalt recycling methods ...

Abstract: From the road user’s point of view the night-time visibility of road markings during wet conditions is of great importance, and instruments aimed for mobile measurement of the retroreflectivity of road markings are available. ...

Abstract: Styrene-butadiene-styrene (SBS) polymer modified binders consist of two-phase (polymer-rich and asphaltene-rich) mixtures. This type of system is thermodynamically unstable, and a phase separation may occur under the ...

Abstract: This paper examines the question of an appropriate failure criterion for asphalt fatigue characterization. The results presented are based on cyclic fatigue tests and obtained from three mixtures containing different ...

Abstract: During recent decades, a considerable amount of research has been devoted to the resilient properties of unbound road materials. However, the severe effects of cold region climates on resilient behavior have been less ...

Abstract: Although elastic multilayer techniques for pavement analysis have become increasingly popular through advances in software and personal computers, the difficulties of such methods in representing dynamic loading, pavement ...

Abstract: Although the effects of climate on pavement structures are recognized as major contributors to the deterioration of pavement structures in cold regions, only a few models concerned with both frost heave and thaw settlement ...

Abstract: The permanent strain behavior of unbound aggregates under repeated loading has been studied by many researchers over the years. A summarized review of the research into this area is given based on the literature available ...
