摘要

本研究探讨了在沥青中加入樱桃和酸樱桃基生物炭的化学、微观结构和流变特性。生物炭是由工业樱桃废料（CW）和酸樱桃废料（SCW）通过缓慢热解产生的，并以 13%、15% 和 17% 的重量比例添加到沥青中。利用扫描电子显微镜进行的微观结构分析表明，沥青表面形态多孔、粗糙，以酸樱桃废料为基础的生物炭比以工业樱桃废料为基础的生物炭的粒度更细。常规测试表明，生物炭的添加量与生物炭的比例成正比，从而增加了沥青的硬度。在沥青中加入 CW 和 SCW 会导致粘度增加（最大值分别为 2.40 倍和 2.59 倍），对温度变化的敏感性降低。渗透指数 (PI) 值从 -3.23 增加到 -2.45，表明其行为已从溶胶过渡到溶胶-凝胶。振荡测试表明抗车辙能力增强（64ºC 时，未老化的 CW 和 SCW 混合物的复合模量 G* 分别增加了 1.94 倍和 1.83 倍）。不过，改性混合物在老化后更容易失去弹性。蠕变恢复分析表明，64ºC 时，在 3.2 kPa 的应力作用下，CW 和 SCW 混合物的抗剪性能有所改善，Jnr 分别降低了 2.19 倍和 1.99 倍，而弹性恢复（R%）则分别降低了约 1.15 倍和 1.06 倍。傅立叶变换红外分析表明，热解后 CH₃ 和 CH₂ 振动减弱，羟基减少。

Effects of using biochar materials obtained from cherry and sour cherry wastes on bitumen modification

This study explores the incorporation of cherry and sour cherry-based biochar into bitumen regarding the chemical, microstructural and rheological properties. Biochar was produced from industrial cherry waste (CW) and sour cherry waste (SCW) via slow pyrolysis and introduced to bitumen with 13 %, 15 %, 17 % by weight. Microstructural analysis using SEM indicated a porous, rough surface morphology, with SCW-based biochar displaying a finer particle size than CW-based biochar. Conventional tests showed that biochar addition increased bitumen stiffness in proportion to the biochar ratio. Incorporation of CW and SCW to bitumen resulted with viscosity increase (maximum 2.40 and 2.59 times, respectively) and less sensitivity to temperature variations. Increased penetration index (PI) values from −3.23 to −2.45 suggested a transition from sol to sol-gel behavior. Oscillation tests demonstrated enhanced rutting resistance (1.94- and 1.83-times greater complex modulus, G* at 64ºC for unaged CW and SCW incorporated blends). However, modified blends showed higher susceptibility to elasticity loss following aging. Creep-recovery analysis revealed improved shear resistance with 2.19- and 1.99-times reduced Jnr at 64ºC under 3.2 kPa stress, while approximately 1.15 and 1.06 times decreased elastic recovery (R%) for CW and SCW incorporated blends, respectively. Fatigue properties were enhanced, with higher A and lower B parameters yielding increased number of cycles to failure (Nf), particularly for 1.35 and 1.26 times for CW-and SCW-modified asphalt binders FTIR analysis revealed diminished CH₃ and CH₂ vibrations, along with a decreased presence of hydroxyl groups after pyrolysis.

期刊介绍： Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged. Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
