In recent years, electrospray ionization (ESI) coupled with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been widely applied for characterizing nitrogen compounds in crude oil and its distillates [11, 12, 13, 14, 15], oil bitumen sands [16], and shale oils [17, 18].
The other three cores were pre-flooded at 280°C with large pore volumes (>8) of bitumen and brine either as a co-injection mixture (1 1 and 19 1 bitumen to brine) or as alternate slugs.
Later, recycled aggregates were introduced in asphalt mixes using either 60/70 bitumen or 80/100 bitumen.
Besides, the BBR test result manifests that the anti-aging modifier can improve the low-temperature rheological performance of 90# bitumen after PAV aging, and has little influence on that of 70# bitumen and 110# bitumen after PAV aging.
However, 60/70 bitumen increased the resilient modulus and skid resistance of the asphalt mixes compared to 80/100 bitumen.
Panjin70# bitumen and SBS-modified bitumen were used as binders and granite acid stone was used as the aggregate.
The absence of genotoxicity in the group exposed to 100 mg/m3 bitumen is discussed with regard to dosage of inhaled polycyclic aromatic compounds and species.
It was observed that the best performance belonged to the mixtures containing B70/100 bitumen, while the worst performance was found for the mixtures made from B160/220 bitumen.
The first involved assessing the effects of incorporating different amounts of CBs (10 kg/m3, 15 kg/m3 and 25 kg/m3) encapsulated with different classes of bitumen (C170, C320, C600) into an AC mix manufactured with Class 170 bitumen.
The average absolute deviations (AADs) between the measured solubility data and the modeling results are within 0.57% for the five H2/heavy alkane systems and 0.69% for the H2/Athabasca bitumen systems.
