Background Reactive organic compounds are precursors to secondary organic aerosols, which are a major contributor to environmental pollutants negatively impacting human health outcomes. Additionally, the loss of latter organic compounds is closely related to aging in the binder used in asphalt pavements, which increases the cost and resources needed...

Background The quality and service life of an asphalt mixture depends largely on the strength and stability of the bitumen-aggregate adhesion. Inadequate adhesion results in typical instabilities such as crumbling, stripping, raveling, pothole development, and a reduction in tensile strength. Organosilane-based technologies have been used to improve...

Background Production and use of air-blown bitumen involves blowing heated air onto vacuum bottom (VB) to increase its stiffness to a desired point. The vacuum bottom is made from refining crude oil, and is mostly in the form of a heavy liquid. The mechanism of air blowing mainly relies on the oxidation of light compounds of VB via heated air, which...

­Background Bitumen, also known as asphalt, is a mixture of hydrocarbons and is used in roads, runways, bridge decks, roofs, and in other waterproofing materials. In the construction industry, recycling asphalt pavement has both economic and environmental benefits. Reclaimed asphalt pavement (RAP), which is typically prepared from old roads, can...
