In this study, we analyzed the potential of employing an innovative eco-friendly resin-based binder, rather than bitumen, for the production of emulsions intended for road pavement applications. Therefore, the goal of this research was to better understand both the novel biobinder and new bioemulsion design and manufacturing processes. Initially, the resin-based biobinder underwent comprehensive characterization. Three physical properties—needle penetration, ring and ball softening points, and density—were determined. Fourier-transform infrared spectroscopy (FTIR) was employed to analyze the chemical functionality. Furthermore, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were conducted to investigate the thermal properties of the biobinders. Lastly, rheological analysis of the resin-based biobinder was carried out utilizing viscosity graphs generated by a dynamic shear rheometer (DSR). The results were compared with those obtained for two commercial penetration-grade bitumen samples (B35/50 and B50/70). Secondly, some bitumen emulsions (bioemulsions) were manufactured using 100% of resin-based biobinders in place of bitumen. These bioemulsions were characterized using standard tests for bitumen emulsions. Resin-based biobinders exhibit considerable potential. Specifically, their penetration grade closely resembles that of commercially available penetration-grade bitumen. Moreover, their light coloration facilitates the production of environmentally harmonious pavements. Furthermore, a notable enhancement in workability was attained. Additionally, all bioemulsions met standard specifications. Owing to their viscosity and other characteristics, these bioemulsions could be obtained at lower temperatures with ease, enabling the preparation of emulsions with higher proportions of binder. This, in turn, implies reduced energy consumption and consequently, diminished CO emissions.

用于道路路面应用的由树脂基生物粘合剂制成的可持续乳液的表征

在这项研究中，我们分析了采用创新的环保树脂基粘合剂（而不是沥青）来生产用于道路路面应用的乳液的潜力。因此，本研究的目标是更好地了解新型生物粘合剂和新型生物乳液的设计和制造工艺。最初，基于树脂的生物粘合剂进行了全面的表征。测定了三种物理特性——针入度、环球软化点和密度。采用傅里叶变换红外光谱（FTIR）来分析化学官能度。此外，还进行了热重分析（TGA）和差示扫描量热法（DSC）来研究生物粘合剂的热性能。最后，利用动态剪切流变仪（DSR）生成的粘度图对树脂基生物粘合剂进行流变分析。结果与两个商业渗透级沥青样品（B35/50 和 B50/70）获得的结果进行了比较。其次，一些沥青乳液（生物乳液）是使用 100% 树脂基生物粘合剂代替沥青制造的。使用沥青乳液的标准测试来表征这些生物乳液。树脂基生物粘合剂表现出巨大的潜力。具体来说，它们的针入度等级与市售的针入度级沥青非常相似。此外，它们的浅色有利于生产环境和谐的路面。此外，作业性也显着提高。此外，所有生物乳液均符合标准规格。由于其粘度和其他特性，这些生物乳液可以在较低温度下轻松获得，从而能够制备具有更高比例粘合剂的乳液。反过来，这意味着能源消耗的减少，从而减少二氧化碳的排放。
