Fortunately, the utilization of WEO as an additive in asphalt pavement crack sealant offers both economic benefits and engineering feasibility. In this study, an eco-friendly crack sealant was prepared using WEO and crumb rubber (CR) modified asphalt (WCRA). The viscoelasticity, storage stability, adhesion, and water resistance properties of the sealant were tested to evaluate its suitability for crack repair. In addition, molecular dynamic (MD) simulation was employed to elucidate the interface adhesion mechanism of the sealant-crack wall interface. The test results demonstrated that the viscosity of the sealant is primarily proportional to the content of CR and inversely proportional to WEO. Furthermore, the storage stability is satisfactory after the addition of moderate WEO. The medium and high temperature flexibility of the sealant is between base asphalt and SBS-modified asphalt. Based on the laboratory tests, 35% (by weight of base asphalt) microwave-treated CR and 25% (by weight of CR) WEO are the optimal proportions for preparing the sealant. MD simulation demonstrated that CR inhibits the diffusion of asphalt components and aggregates asphaltenes in close proximity to the crack wall surface. WEO not only stimulates molecular activity but also maintains the equilibrium of the asphalt colloid system, which is conducive to the penetration and water resistance of the sealant. The study will provide a reference for the utilization of waste materials and the cost-effective repair of asphalt pavements.</p></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141540778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These biofillers present diverse fundamental characteristics, making them promising substitutes for carbon black or inorganic mineral-based fillers, reducing reliance on petroleum. They possess biodegradable properties, resulting in a reduced environmental footprint, as well as lower density and cost compared to conventional counterparts. Furthermore, their unique properties, such as high specific strength and stiffness, render them well-suited for various rubber applications.

Rubber composites incorporating biofillers offer the dual advantages of economic efficiency and environmental sustainability.
