Abstract ：
SBS modified bitumen (SMB) is widely used for its excellent physical and rheological properties, but it is susceptible to aging due to exposure to environmental factors such as heat, light, and oxygen. This aging process involves bitumen aging and SBS degradation, which complicates the rejuvenation of SMB. In order to explore the rejuvenation mechanism of aged SMB, particularly emphasizing the rejuvenation effects of epoxy compounds (BUDGE, TMPGE, and RDGE), a combination of molecular dynamics simulation and experiments was employed. The thermodynamic, chemical, and physical properties of rejuvenated SMB were analyzed. Results show that BUDGE and its repaired SBS exhibit excellent flexibility compared to TMPGE, improving cohesive energy density and free volume of aged bitumen, which facilitates recovery of ductility in aged SMB. Conversely, SBS repaired with RDGE increases cohesive energy density of aged SMB while reducing free volume, which enhances stiffness of bitumen. Additionally, rigid groups in RDGE inhibit mobility of both itself and the repaired SBS, leading to a reduction in the ductility of aged SMB to 10.1 cm. Besides, SBS repaired with RDGE shows strongest binding with resins and aromatics, which diminishes lubricating effect of these components on asphaltenes. This reduction in lubrication enhances aggregation of asphaltenes, ultimately raising flow resistance.

Abstract ：
The diglycidyl ether (HDDGE) and dicyclohexylmethane diisocyanate (HMDI) are widely adopted as active rejuvenators in the field of regenerated SBS modified bitumen (RSMB), which can react with the oxygen-containing functional group on the aged SBS, thereby rebuilding the crosslinking net of the SBS. Numerous measurements indicate that HDDGE negatively affects the high-temperature performance of RSMB, while HMDI impairs its low-temperature performance. This unexplained phenomenon continues to impede the effective regeneration of bitumen. To reveal the underlying mechanism of this phenomenon, this study investigates the SBS-bitumen interface inside the RSMB thought the molecular dynamics simulation, and conducts the experiments in the lab to prove the inference. Results indicated that the type and dosage of rejuvenators will affect the H-bonds inside regenerated SBS, which will change the configuration of SBS molecules. Subsequently, the regenerated SBS molecules will redetermine the fractions located at the SBS-bitumen interface thought the space steric hindrance effect and interaction between SBS and bitumen, which will alter the colloid structure of RSMB. This will significantly change the free volume of the RSMB, and will finally affect the macro-properties of RSMB. © 2025 Elsevier B.V.

Abstract ：
The shortages of river sand and freshwater in marine engineering can be addressed by utilizing seawater and sea sand concrete (SWSSC). However, the sulfate resistance of SWSSC at low temperature is not clear. In this study, the seawater and sea sand cement mortar (SSCM) and ordinary cement mortar (OCM) with different limestone powder (LP) content were corroded by different sulfate solutions at 5 degrees C. The change of compressive strength and compositions of corrosion products in mortars after different times of corrosion were studied. The results show that SSCM presents 9.4 similar to 19 % lower strength loss and better sulfate resistance than OCM. The presence of Friedel's salt in SSCM contributes to a reduction in corrosion products like ettringite, gypsum, and thaumasite, thereby minimizing microstructural damage and mitigating the thaumasite sulfate attack (TSA). All mortars containing LP suffer from TSA and significantly damage with 17.4 similar to 48.7 % strength loss after 360 days of MgSO4 or Na2SO4 corrosion. Increasing the LP content exacerbates the TSA damage in SSCM. This is primarily due to the additional soluble carbonate from LP promoting the formation of gypsum and thaumasite, thereby worsening the microstructure deterioration of SSCM. Meanwhile, the thaumasite is not found in SSCM without LP after corrosion. In contrast to Na2SO4 corrosion, the thaumasite formation under MgSO4 corrosion mainly results from indirect reaction. The combined corrosion effects of Mg2+ and SO42- lead to a more significant increase in expansive products (thaumasite and gypsum) and TSA damage. The findings of this study help to advance the sulfate resistance of SWSSC in marine environments.

Abstract ：
In this study, a novel approach based on Munsell value was established to reveal the relationship between the aging degree and color vision of asphalt. Five different asphalt binders were treated by three types of aging protocols such as thin film oven test (TFOT), pressure aging vessel (PAV), and ultraviolet (UV) radiation, then the effects of each aging treatment on the ductility and color spectrum (collected by a spectrometer, AvaField-3) of the binders were studied. The results show that the ductility of five binders is decreased after the three aging modes (including TFOT, PAV and UV aging), nevertheless, the Munsell values show different behaviors, they become smaller after TFOT and PAV aging while becoming larger after UV aging. Scanning electron microscope (SEM) photographs show that the UV aging leads to a transformation of the binder's surface from smooth to pleated, thus the specular reflection of the asphalt surface changes into diffuse reflection, resulting in an increase in Munsell value of asphalt after UV aging. Meanwhile, the variation of Munsell value for the asphalt after UV aging is larger than that for asphalt after thermal oxidative aging, resulting in the increase of Munsell value of asphalt which undergoes thermal oxidative aging and UV aging. Based on field data collection and analysis, a linear regression equation (R2 = 0.915) is established between the Munsell value and the service life of asphalt pavement, which shows that the asphalt pavement will become white with the service life-prolonging. Based on this study, the method of Munsell value can be a promising approach to evaluate the aging degree of asphalt pavement.

Abstract ：
High-quality limestone, as a nonrenewable resource, is decreasing with the maintenance and construction of asphalt pavements. Meanwhile, due to the growth of the shell farming industry, a great amount of waste shells is produced annually, which are mainly disposed in the manner of stacking, landfill, or discarding into the sea directly, leading to serious environmental pollution. This research used mussel, pectinid, oncomelania, and oyster as raw materials to prepare four shell fillers, aiming at substituting nonrenewable mineral resources and recycling the waste shells at the same time. The asphalt mastics were prepared by mixing the base and SBS-modified asphalt with four shell fillers under different filler-asphalt ratios, respectively, and the asphalt mastics with limestone were adopted as control groups. The physical and rheological properties of five asphalt mastics were evaluated, and the chemical composition and the microstructure of five fillers were measured to investigate the acting mechanism between the fillers and asphalt. Results indicate that shells have lower density, hydrophilicity coefficient, and higher specific surface area than limestone, exhibiting a better compatibility with the asphalt. For the properties, in both base and modified asphalt mastics, the mastics with pectinid and oyster shells exhibit the lowest penetration and phase angle, while their complex modulus and softening point are the highest among the five types of mastics, indicating the better antideformation ability. Moreover, with the increasing filler-asphalt ratio, the antideformation ability of the base asphalt mastic increases gradually, while the SBS-modified asphalt mastic exhibits a more complex behavior. In addition, analysis results of fillers demonstrate that the looser structure of shells is attributed to the interlaced layered structure of aragonite and calcite, leading to a larger contact area between the shell and asphalt. Besides, there is some organic matter present in the shell, which plays a role like organic modification, improving the compatibility between the shell and asphalt. The larger contact area and the presence of organic matter in the shell show a synergistic effect in improving the road performance of asphalt mastic. This work verifies the feasibility to replace the conventional mineral fillers with shell fillers, which is beneficial to recycle the waste shell and reduce the consumption of nonrenewable mineral resources.

Abstract ：
SBS modified asphalt (SBSMA) pavements have gained popularity worldwide due to their prominent performance. However, its maintenance and reconstruction projects will produce a large amount of reclaimed asphalt pavement (RAP) during the long-term service of asphalt pavement. Adding rejuvenators products is a common method to recycling RAP. However, conventional rejuvenators are typical component regulators applicable to recycling unmodified asphalt, while there is a poor regeneration effect for the aged SBS modified asphalt (ASBSMA), because it cannot repair the degraded SBS polymer. Fortunately, reactive rejuvenator (RR) has achieved this breakthrough based on the research findings in recent years. It contains special compounds that have the ability to repair the degraded SBS. The vital questions to be investigated in the present review are how the four current systems of RR (epoxy system, isocyanate system, compound system and polymer system) affect ASBSMA's properties and how well does its regeneration effect. Existing research indicated that RRs are favorable for the regeneration of A-SBSMA and have their respective characteristics. This review summaries various RR different regeneration mechanism, and analyzed its effects on physical properties, rheological properties, high and low temperature properties, and microscopic characteristics of A-SBSMA. Although research on RR is still in its infancy with a limited number of relevant studies, they show an excellent regeneration effect for A-SBSMA and hold a promising prospect. Overall, this review provides information on the feasibility of using RR as a sustainable SBSMA rejuvenator to promote conserving resources and reusing RAP.

Abstract ：
The cinnamic acid intercalated layered double hydroxides (CA-LDHs) were prepared by anion exchange method and analyzed by X-ray diffractometer (XRD) Fourier transform infrared (FTIR) spectrometer, scanning electron microscopy (SEM), contact angle goniometer, ultraviolet and visible (UV-vis) spectroscopy, and thermogravimetric (TG) analysis system. Then, the CA-LDHs were added to styrene-butadiene-styrene (SBS) modified bitumen together with an antioxidant composed of octadecyl-3-(3,5di-tert-butyl-4-hydroxyphenyl)-propionate (1076) and tris(2,4-di-tert-butylphenyl) phosphite (168) at a mass ratio of 1 : 1. The effects of antioxidant/CA-LDHs on the physical and rheological properties and chemical composition and characteristics of SBS-modified bitumen before and after pressurized aging vessel (PAV) and ultraviolet (UV) aging were investigated. The results revealed that CA was successfully intercalated into the interlayer space of LDHs. Meanwhile, the CA-LDHs performed improved hydrophobicity and UV absorption capacity compared with LDHs, resulting in enhanced compatibility of LDHs with SBS-modified bitumen, and then the antiaging properties of SBS-modified bitumen could be further strengthened, especially the anti-UV aging properties. Moreover, the mixture of antioxidants and CA-LDHs could synergistically improve the SBS-modified bitumen's thermal- and photo-oxidative aging resistance.

Abstract ：
The shell farming industry generates significant waste shells annually, often improperly disposed of, causing environmental pollution. Concurrently, pavement engineering faces a shortage of limestone resources. Utilizing waste shells as a substitute for limestone fillers could simultaneously address both environmental and resource challenges. To analyze the feasibility of this strategy, this work collected the mussel, pectinid, oncomelania and oyster as the raw materials, and the method of organic modification was adopted on these shells to enhance the compatibility between the filler and asphalt. Asphalt. The physical and rheological properties of the prepared asphalt mastics were evaluated, and the modification effect was determined by the contact angle test and the surface energy parameters. Results indicated that the asphalt mastics with modified shells had higher penetration and ductility while lower softening point compared to the mastics with unmodified shells. Moreover, the modification with aluminate coupling agent had more significant impact on the physical properties of the asphalt mastics than that using amino silicone oil. For the rheological properties, shell asphalt mastics exhibited an extremely complex rheological behavior due to the various polarity and the organic content of the shell fillers. Besides, the contact angle of the shells increased after the modification, implying a better compatibility with asphalt. Moreover, the results of the surface energy parameters indicated that the non-polar component of the shells increased obvious after modification. In comparison with the conventional limestone, it can be found that the modified shells enhanced the adhesion between the aggregates and the asphalt mastics, which can improve the resistance of asphalt mixture to water damage. This work verifies the feasibility to replace the conventional mineral filler with modified shell filler, which was beneficial to recycling the waste shell and reducing the consumption of non-renewable mineral resources.

Abstract ：
The thermal-oxidative aging of asphalt is extensively researched in recent years. However, the aging behavior of asphalt in salt and water environment receives less attention. A virgin asphalt binder was treated by various coupling conditions of salt and water in this work aiming at understanding the aging behaviors, and then the physical indexes, rheological parameters, chemical structures, four fractions and contact angles of asphalt before and after aging were measured to evaluated the effects of different aging environments on the physicochemical properties of asphalt. Results indicate that the aged asphalt has higher softening point and complex modulus while lower penetration and phase angle in comparison with unaged asphalt, implying the asphalt becomes harder and more brittle after aging. Although asphalt aged in salt and water conditions exhibits similar changes in macro-properties to thermal-oxidative aged asphalt, the analysis of chemical composition indicates that the aging of asphalt under salt and water environment is caused by unique inducements, which can be divided into two parts, that is, separating out of aromatics and saturates from asphalt by combined action of salt out and emulsification, and increasing of asphaltenes and resins caused by oxidation. These two factors work together leading to the change of colloidal structure and finally cause the deteriorate of macro-properties. Besides, the results of contact angle test indicate the increasing polar functional groups resulting from aging enhance hydrophily of asphalt and increase the possibility of water to enter the interior of asphalt, exacerbating the performance degradation of asphalt.

Abstract ：
Seawater sea sand concrete (SWSSC) is considered a potential solution to the shortage of river sand and freshwater resources in the coastal and island regions. Under the marine environment, the sulfate ions in the seawater and sea sand are detrimental to the properties of concrete. Due to the lack of systematic research on the sulfate attack characteristics of SWSSC exposed to different marine conditions, this study compare the sulfate resistance between SWSSC and freshwater desalinated sea sand concrete (FDC) under full immersion, semi -immersion, and dry -wet cycle exposure through the compressive strength, sulfate ion distribution, and microstructural changes after erosion. The findings showed that among the three different exposure conditions, the damage in SWSSC-F (fully immersion) was more severe than that in SWSSC-S (semi -immersion) and SWSSC-DW (dry -wet cycle). The SO42- concentration in inner SWSSC-F was 9.3% and 21.3% higher than that in SWSSC-DW and SWSSC-S, respectively. The microstructural analysis indicated that the higher amount of sulfate attack products and the leaching of Ca2+/OH- in SWSSC-F significantly damaged its microstructure. Besides, carbonation and physical crystallization in SWSSC-S and SWSSC-DW also refined their pore structure, thus enhancing their sulfate resistance. SWSSC showed better sulfate resistance than FDC under different marine exposure conditions in terms of lower erosion product content and better pore structure distribution after 12 months of erosion. The formation of Friedel's salt in SWSSC suppressed the formation of expansion products and reduced the erosion damage of concrete by SO42-.
