Conventional bitumen pavement is no longer suitable for handling increasing loads and
weather variations, which cause road deterioration, Thus, the modification of bitumen has …

In order to seek alternatives to petroleum asphalt and expand the practical engineering
usage of castor oil bio-asphalt, the polyphosphoric acid (PPA) was applied to the …

Polyphosphoric acid (PPA) had a significant benefit as a supplemental modifier to improve
the performance of polymer modified asphalt and bio-asphalt due to the presence of network …

The asphalt binder of permeable asphalt concrete has high requirements and there are few
studies on mixing reclaimed asphalt (RA) with high-viscosity asphalt (HVA) for recycled …

Crack sealing is an important measure for pavement maintenance. Hot-poured crack sealant
is the most utilized material for crack sealing. However, its poor high-temperature and …

To explore the performance evolution mechanism of SBS-modified bitumen (SMB) during
construction and service, the chemical structure, molecular weight and properties of styrene …

In this research, the effects of modifiers on the high-temperature rheological and fatigue
properties of asphalt were investigated by utilizing montmorillonite (MMT) and organic …

The objective of this study was to explore the effect of polyphosphoric acid (PPA) on the low-
temperature creep properties of styrene–butadiene-styrene (SBS) and crumb rubber (CR) …

To enhance the properties of SBS and crumb rubber-modified asphalts, four different
amounts (5%, 10%, 15%, and 20%) of castor oil were added to crumb rubber-modified …

A large amount of soybean oil (20%–30% mass ratio of neat asphalt) was selected to
partially replace petroleum asphalt. The high-temperature behavior of soybean oil …
