Adhesion Characteristics of an Asphalt Binder–Aggregate Interface Based on Molecular Dynamics

Materials, Год журнала: 2025, Номер 18(5), С. 981 - 981

Опубликована: Фев. 23, 2025

To investigate the adhesion properties of asphalt binder-aggregate interfaces, contact angle tests were performed on base, aged, and SBS# with limestone basalt aggregates. A molecular dynamics simulation model was established to analyze interfacial characteristics. The results indicate good consistency between experimental findings. exhibited superior surface free energy compared base asphalt, whereas aging reduced performance. aggregates is closely related their compositions. When moisture penetrates mixture, significantly increases, that basalt, exhibiting stronger than asphalt. modifier enhanced aggregates, thereby providing resistance damage. findings this study possess referential value for selection, modification, performance optimization pavement materials.

Low-Temperature Cracking and Improvement Methods for Asphalt Pavement in Cold Regions: A Review

Buildings, Год журнала: 2024, Номер 14(12), С. 3802 - 3802

Опубликована: Ноя. 28, 2024

The advantages of asphalt pavement in terms driving comfort, construction efficiency, and ease maintenance have established it as the predominant choice for high-grade pavements at present. However, being highly sensitive to temperature stress, performance is significantly influenced by external environmental conditions loading, making susceptible various distress phenomena. Particularly high-latitude regions, cracking severely limits pavement’s functional service lifespan under cold climatic conditions. To enhance low-temperature resistance tools such VOS viewer 1.6.20 Connected Papers were utilized systematically organize, analyze, summarize relevant research from past 40 years. results reveal that shrinkage cracks thermal fatigue represent primary forms these regions. Cracking regions primarily structural design, materials, technology, Among factors, surface layer stiffness, base type, rate decrease exert most significant impact on resistance, collectively accounting approximately 45.4% all cracking-related factors. can be effectively improved through several strategies, including adopting full-thickness with a skeleton-dense structure or reduced average particle size, incorporating layers, appropriately increasing thickness upper compaction lower layer, utilizing continuous techniques, applying advanced materials. High-performance modifiers SBR SBS, nanomaterials good performance, warm mixing processes designed proven particularly effective. improvement methods, modification has demonstrated superior effectiveness enhancing deformation capacity its mixtures, boosting pavements. Asphalt accounts 50% methods evaluated this study, an reaching up 143%. This paper provides valuable insights into underlying causes offers essential guidance improving quality challenging environments.
