Initially, it discussed the importance of SBS MA within asphalt modification systems and identified the key nanomaterials utilized in SBS modified asphalt. After this, it reviewed their preparation methods, dispersion and characterization techniques, and their impact on the key performance parameters of SBS MA binder and its mixture such as viscosity, rutting resistance, fatigue resistance, ageing and moisture damage etc. Additionally, it highlighted the advantages of nanomaterials over other modifiers. This study also addressed the challenges and limitations of incorporating nanomaterials in SBS MA. The findings indicated that when properly integrated, nanomaterials could significantly improve the performance of SBS MA, making them a promising addition to future road construction and maintenance projects. However, using nanomaterials for SBS MA modifications and mixtures has been challenged by limited practical applications, insufficient life cycle cost analyses, a lack of standardized guidelines, cost-effective nanomaterials and insufficient mixing procedures.

However, concerns arise regarding the performance of HRAM due to the lower degree of blending (DOB) of virgin and aged asphalt (V&amp;A asphalt). This paper aims to provide an up-to-date review on the DOB of V&amp;A asphalt in HRAM. Initially, the paper introduces the DOB of V&amp;A asphalt, followed by an analysis of the blending theory, evaluation methods, and influencing factors of DOB. Subsequently, the effect of DOB on the performance of HRAM is investigated, and molecular dynamic simulation is utilized to analyze the blend of V&amp;A asphalt. Finally, methods for improving DOB are summarized. It was found that the use of high-resolution microscopy with tracer methods such as SEM/EDS was an effective way to characterize DOB. Furthermore, the chemical composition and colloid structure between virgin and aged asphalt are crucial to DOB. Additionally, improving DOB by utilizing the coupling effect of time and temperature during transportation, paving, and compaction stages is promising. Future research should focus on standardizing test methods, refining field simulation models, and developing intelligent construction technologies to achieve more efficient and durable blending.

The primary parameter used to evaluate the resilient response of UGMs in pavements is the resilient modulus (MR). The MR is widely used in calculating stress-strain states for flexible pavement design and as a control parameter during the construction process. It is also employed to understand the progression of distresses, such as fatigue cracking and rutting. The main objective of this study was to conduct a literature review on the resilient behavior of UGMs. This manuscript presents and describes the MR and the factors that influence it. It also outlines the evolution of the mathematical equations most commonly used to estimate and predict this physical parameter. Conclusions and recommendations for future research are provided at the end of the article. Despite the large amount of research done on the subject, the resilient behavior of UGM has not yet been fully understood. This is since these materials are highly heterogeneous and show nonlinear-anisotropic behavior under different cyclic loading paths and water contents. Likewise, these materials undergo different behaviors depending on their macro and microscopic properties (gradation, density, porosity, texture, mineralogy, particle geometry and orientation, temperature, among others). On the other hand, the main limitation of the mathematical equations is that their parameters are difficult to determine experimentally and are not constants of the material (they are state variables that can change with multiple factors). Additionally, these equations do not consider the boundary conditions to which UGM in pavements are exposed. Moreover, they are obtained from repeated load triaxial (RLT) tests, which cannot simulate the three cyclic stress components (vertical, horizontal, and shear) to which UGMs are subjected in a pavement. In recent years, there has been an increase in studies evaluating the use of recycled aggregates and the effect of temperature (particularly at subzero temperatures), but more research is still needed to reach definitive conclusions.</div></div>","PeriodicalId":100830,"journal":{"name":"Journal of Road Engineering","volume":"5 3","pages":"Pages 394-413"},"PeriodicalIF":8.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144997635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 2D laser analysis aims at collecting surface texture indicators, while noise-related indicators were derived according to ISO 10844 standards. Noise levels were predicted using the SPERoN® model (statistical physical explanation of rolling noise), analysing the vibro-dynamic and the aerodynamic contributions separately. Correlations between tire/road noise levels predicted by the model and surface texture indicators elucidate the key factors influencing noise generation mechanism. The findings indicate that lower nominal maximum aggregate size (NMAS) and uniformly shaped artificial aggregates substantially mitigate rolling noise.

This paper summarized and analyzed the impact of plateau environments on concrete’ properties and proposed methods to improve the performance of concrete in plateau environment. The results indicated that low humidity and high evaporation rates in plateau regions inhibit the hydration of cement in concrete, leading to an increased content of micro-pores ranging from 500 to 1000 ​nm and raising the risk of early-stage cracking, thus reducing the impermeability of concrete. The low atmospheric pressure (AP) condition of 60 ​kPa decreases the entrained air content in concrete by over 20%, diminishes the pores under 200 ​μm, and increases the average air-voids diameter and spacing factor, resulting in a decrease of more than 5% in the 28 ​d compressive strength of concrete. Consequently, the durability of concrete is compromised. Saponin and rosin-based air-entraining agents are recommended to improve the performance of concrete in plateau environments.
