Wax in asphalt is an important factor that affects the life cycle cost of flexible pavements. Due
to limitations in characterization methods for asphalt microstructure, deficiencies in our …

Deep cold recycling with foamed bitumen (FB-RCM) is currently one of the most widely used
road rehabilitation methods. As the percentage of reclaimed asphalt pavement (RAP) in the …

This work aims at exploring the impacts of phase change materials (PCMs) in asphalt
pavement, particularly regarding their potential of minimizing high temperatures, responsible …

Environment conservation and diminishing natural resources caused an increase in
popularity of the application of renewable bio-origin resources for the construction of road …

The process of water-based foaming of bitumen produces binders that can be incorporated
in cold recycled asphalt mixes and pavement upper structural layers made of half-warm mix …

Current regulations regarding emissions, as well as the efforts focused on reducing energy
intensity of building materials production create a need for implementing new road …

Half-warm mix asphalt (HWMA) mixtures can be produced at temperatures ranging from
100° C to 130° C, depending on the production methods used. The lowest mixing …

Most bitumen contains some level of wax, and the widespread use of wax-based additives in
asphalt industry further increases bitumen's wax content. Wax-based additives reduce …

Hot-mix asphalt (HMA) remains the predominant material for pavement surfacing. Mixing is
performed at about 180° C, depending on the bitumen used. Environmental concerns in …

This article discusses the results of bitumen foam properties optimisation with respect to
three factors: air pressure, bitumen temperature and amount of water. The test materials …
