The global population spike, rise in industrialization, and highway infrastructure
development induce focus on sustainable development. The ever-increasing consumption …

To promote the application of environmentally-friendly and sustainable bio-asphalt (BA) in
road engineering, polyphosphoric acid (PPA) and styrene–butadienestyrene (SBS) were …

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 …

This study investigates the performance of polyphosphoric acid/styrene–butadienestyrene
(PPA/SBS)-modified bio-mixed asphalt after thermo-oxidative and ultraviolet (UV) aging …

Polyphosphoric acid (PPA) plays an important role in improving the performance of polymer
modified asphalt binders. This study aims to understand the modification mechanism of PPA …

Substituting petroleum asphalt with bio-asphalt produced by biological waste recycling can
mitigate the dependence on non-renewable resource oil. This study aimed to investigate the …

Traditional evaporators for the concentration of wet process phosphoric acid (WPA) suffer
from concentration, corrosion, and low fluorine yield (less than 40 wt.%). Based on the …

This paper examines the effect of polyphosphoric acid (PPA) on asphalt's fracture properties.
While PPA has been commonly used in the asphalt industry to increase the elasticity and …

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 …

In response to the growing demand for energy-efficient and sustainable materials in road
construction, this research presents a pioneering method to enhance the engineering …
