Summary: This study investigates the effect of laboratory-simulated ageing on Polymer Modified Bitumens (PMBs) and finds that cross-linked polymers have a higher capability of mitigating the hardening effect on bitumen rheological response compared to uncross-linked PMBs. The study also shows that the chemical composition of unmodified bitumens shifts towards heavier molecules after ageing, with limited variation with further ageing.

Summary: This study investigates the effects of laboratory ageing on the damage tolerance of cross-linked SBS and EVA modified bitumens and the results are corroborated with the morphology of PMBs. The findings suggest that ageing reduces the integrity and time-temperature susceptibility of bitumens, and the damage tolerance is influenced by the bitumen's strain level and the concentration of the polymer used for modification.

Summary: Among piezo composites, 0-3 type ceramic/polymer-based composites have balanced properties and flexible manufacturing processes, allowing them to tackle challenges in wearable electronics and sensing technology. This study presents a novel poling method that combines normal corona poling and oil-based poling methods to activate a lead zirconium titanate (PZT)/Polyethylene glycol diacrylate (PEGDA) composite. The optimized poling parameters for the 0-3 PZT/PEGDA composites were found to be 60 min poling duration, 25 degrees C, and 24 kV. The proposed poling method showed significant improvement in the piezoelectric properties compared to the normal corona poling method.

Summary: This study analyzed the variation of self-healing temperature susceptibility of bitumen under different ageing states. The results show that the self-healing rate of bitumen evolves in a parabolic pattern with temperature, which is related to its frequent phase transition behavior. Ageing leads to the increase of heavy components, the decay of colloidal and phase structures, resulting in changes in the self-healing curves. All-weather ageing has a more severe impact on the self-healing temperature susceptibility of bitumen compared to thermal oxidative ageing. Rock-asphalt modified bitumen has greater ageing resistance and undergoes less ageing impact on self-healing temperature susceptibility compared to pure bitumen.

Summary: The PABA-LDHs were prepared by intercalating para-aminobenzoic acid into the layers of LDHs through anion exchange, which effectively improved the aging resistance of bitumen by reflecting and absorbing UV rays and blocking oxygen. The composite modification of PABA-LDHs with 1076 and 1010 further enhanced the thermal and photo-oxidative aging resistance of bitumen, exhibiting a complementary effect. Furthermore, 1076/PABA-LDHs modified bitumen showed superior anti-aging property compared to 1010/PABA-LDHs modified bitumen.

Summary: This study identifies undisclosed crystalline modifiers (UMs) in high polymer-modified binders (HiPMBs) and evaluates their effects on aging phenomena using thermo-chemical and microstructural analyses. The properties of several industrial HiPMBs were evaluated through FT-IR, DSC, FM, and AFM. Results show that calorimetric analysis can readily identify crystalline UMs in most binders. Unlike SBS thermoplastic elastomers, UMs drastically alter the surface microstructure of all binders, causing the disappearance of typical bee-like structures and the emergence of undefined topographies due to interactions with bituminous waxes. The homogeneity of the binders' amorphous phases is not significantly affected. Aging processes affect base bitumen, SBS, and UMs, with the oxidation of bitumen and degradation of SBS evaluated through FT-IR absorption bands and Tg values, and variations in DSC endotherms reflecting the influence on the crystallinity of UMs.

Summary: This study develops deterministic and probabilistic prediction models for the multiple stress creep and recovery (MSCR) test. Crumb rubber, polyphosphoric acid, and styrene-butadiene-styrene bitumen modifiers are used to modify the high-temperature performance of base bitumens. Deterministic models are developed for each modifier individually, while a comprehensive probabilistic model is developed to predict different traffic levels. The accuracy of the probabilistic model is 0.85, and the sensitivity analysis shows the impact of modifier dosage and temperature on traffic levels.

Summary: This study compared the long-term ageing kinetics of hot mix asphalt (HMA) and warm mix asphalt (WMA) produced with the same base bitumen. It found that the warm agent and foaming water significantly decreased the viscosity of the binder at high temperatures, improving the ageing resistance of the WMA. However, a higher content of foaming water deteriorated the viscosity, suggesting a lower content of warm agent and foaming water is recommended for foamed WMA preparation.

Summary: This paper presents the development of a mechanical crack propagation model coupling viscoelasticity and the extended Griffith's criterion. The model is applied to study the mode I cracking of bituminous materials under intermediate temperature condition and long term ageing duration. The viscoelastic behavior of these materials based on a Generalized Maxwell (GM) model is described and a discretized form of the state equation based on the exponential algorithm is given. The proposed model is validated using simulation of the complex modulus test. The thermodynamic framework of the Griffith criterion is extended to the GM's model and a crack growth criterion is derived. The application of the criterion on a semi-circular bending geometry is presented and validated through numerical simulations and experiments. The study shows that the proposed approach can effectively capture the ductile fracture properties of bituminous mixes.

Summary: This study investigates the multiscale modeling of the complex modulus and phase angle of aged hot and warm mix asphalt and bituminous mortar. The results show that the stiffness moduli of binders and mixes increase with the long-term thermo-oxidative ageing duration, with a more pronounced increase for WMA. A multi-scale model combining Mori-Tanaka scheme and self-consistent scheme is implemented to predict the evolution of the stiffness moduli and phase angles of the mixes.

Summary: An oxidative aging treatment was conducted on fresh 10/20 and 35/50 bitumens in the laboratory to simulate long-term aging on road pavements. The aging treatment resulted in the oxidation of less polar aromatic species into more polar content, as confirmed by FTIR, SAR-AD, and SAXS techniques. The size of nanoaggregates and primary clusters increased, leading to changes in the macroscopic rheological properties of the aged bitumens.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.
