The evaluation of diverse warm mix additives’ impact on diverse asphalt binders involved viscosity, softening point, penetration tests, Fourier transform infrared (FTIR) and analysis of saturate, ...

Qinhuangdao China Petroleum Asphalt is mainly composed of Venezuelan Persian Cane crude oil. This crude oil has high acid value, heavy metal content, and residual carbon, while it has low saturated ...

Recently, the Western Research Institute developed the SAR-AD method that allowed the separation of asphalt into eight fractions (saturates, aromatics 1, aromatics 2, aromatics 3, resins, asphaltenes ...

Conceptualization of the sustainable use of asphaltene. Source: Muhammad M. Rahman et al. Asphaltenes produced during petroleum distillation are deemed as low-value by-products with little to no ...

It is a new soybean oil-derived additive that triggers chemical reactions inside recycled asphalt pavement (RAP) and stiff binders to break down asphaltene aggregation and reverse the effects of ...

The asphalt might flow better and handle better than high-percentage RAP mixes without a rejuvenator, but the rejuvenator most likely will not deliver long-term performance in lower temperatures. “To ...
