Summary: The selective absorption of bitumen by BOF has been studied previously, but research on the selective absorption of bitumen by BOF at different aging stages is still lacking. This study aims to explore the selective absorption behavior of BOF towards bitumen components at different aging and rejuvenation stages, as well as the road performance of the bituminous mixtures at different stages. The results show that BOF and natural aggregates both exhibit selective absorption of bitumen, with BOF showing a more significant effect. The selective absorption of bitumen by aggregates exhibits a time-dependent effect, with the strongest selective absorption seen at the short-term aging stage. The ability of adhesion for bitumen decreases with aging, which is the key factor affecting the performance of bituminous mixtures.

Summary: This study investigates the enhanced reactivity of basic oxygen furnace slag (BOFS) through accelerated carbonation and the combined use of metakaolin (MK). The combination of carbonated BOFS and MK improves the formation of carboaluminate phases and stabilizes ettringite. The consumption of CaCO3 facilitates the pozzolanic reaction of the amorphous SiO2 gel formed during carbonation, leading to improved impermeability and strength development. The study proposes an approach to efficiently improve the reactivity of BOFS and sequester a significant amount of CO2.

Summary: The construction industry is facing a shortage of natural aggregates used in concrete and mortar. This study investigates the viability of using waste basic oxygen furnace slag (BOFS) as fine aggregate to produce cement-based mortar. Experimental results show that the incorporation of BOFS aggregate reduces flow and increases water absorption and drying shrinkage. However, the mortar still maintains reasonable strength and stability when 50% unweathered BOFS aggregate or 100% weathered BOFS aggregate is used as a replacement for natural sand.

Summary: A study was conducted to determine the optimal conditions for aqueous carbonation of basic oxygen furnace slag (BOFS) in order to maximize CO2 sequestration. The carbonated BOFS was found to have a higher sequestration rate compared to dry carbonation, and when used in blended cement paste, it accelerated the early heat evolution but decreased mechanical strength as the replacement ratio increased. Aqueous carbonation was also found to be more effective in enhancing the properties of blended cement paste due to the presence of nucleation sites.

Summary: This paper provides a comprehensive review on the recent developments in utilizing photocatalytic asphalt pavement for reducing vehicle pollutants. It covers the mechanism of photocatalysis, testing facilities, quantifying methods, techniques of applying TiO2 particles onto asphalt pavements, influencing factors on pollutants degradation, and future perspectives. The key factors influencing the efficiency and durability of photocatalytic asphalt pavement include nano-TiO2 crystal types, doping approach, ambient temperature, relative humidity, intensity and time of irradiation, and pollutant characteristics. Currently, photocatalytic asphalt pavement can achieve a degradation efficiency of 55% for NOx pollutants and 20% for SO2 pollutants, but it suffers from short service life due to busy traffics and complex weather circumstances. In the future, practical costs, applying methods, durability, and negative effects are highly emphasized for the development of sustainable and durable photocatalytic roads.

Summary: Using steel slag aggregate in asphalt pavement is considered a novel alternative to enhance environmental benefits. However, the lack of quantitative analysis on its air component emissions has hindered the sustainable development of roads. This study compared the volatile organic compounds (VOCs) and greenhouse gas (GHG) emissions of steel slag and natural aggregate asphalt pavements. Results showed that using steel slag aggregate generated more asphalt VOCs and GHG emissions compared to natural aggregate in the life cycle of asphalt pavement. This research provides valuable insights for air pollution control and low-carbon development of asphalt pavement.

Summary: Moisture susceptibility of asphalt mixtures is a major concern, and this study aimed to investigate the influence of flue gas desulfurization ash (FGDA) on the moisture susceptibility of asphalt mixtures. The results show that FGDA with high alkali minerals and flocculent sphere morphology can improve the dispersivity and compatibility of mixtures and promote the generation of a homogeneous integral structure. Under hydrodynamic damage, FGDA mixtures demonstrate higher shear resistance and durability. The study also suggests that substituting 30% FGDA for limestone filler is appropriate in FLAM.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.
