摘要

生物再生剂是利用可持续生物原料生产的再生剂。本研究在再生材料(如再生沥青路面(RAP))中使用了生物再生剂,以确定其对沥青混凝土磨耗层(ACWC)混合料的沥青粘结膜厚度(ABFT)和弹性模量(Smix)的影响,该混合料在最佳粘结剂含量(OBC)下进行了测试。使用扫描电子显微镜对 ABFT 进行了研究,而 Smix 则是在 20-40 °C 试验温度下使用 UMATTA 通过沥青混合料试验确定的。沥青混合料是用 RAP(0-30%)、Pen 60/70、集料和两种生物再生剂(即椰壳生物沥青(BioCS)和 BitutechRAP(来自树木))制备的。此外,还为每种混合物建立了 Smix 模型。每种混合料的微观结构测试结果得出的 ABFT 值都符合沥青混合料粘附标准的最低 ABFT 要求,从微观结构上证明生物再生剂在恢复 ACWC 混合料中 30%RAP 的性能方面效果良好。两种生物再生剂都能激活 RAP(RA 粘结剂)的沥青,因为它们仍能产生 Smix。RAP 和 BioCS 混合料产生的 Smix 值大于 RAP 和 BitutechRAP 混合料产生的 Smix 值。在得出的 Smix 模型中,对 ACWC + RAP + BioCS 和 ACWC + RAP + BitutechRAP 有影响的体积参数分别是矿物集料中的空隙和沥青中的空隙。根据微观结构模型、机械模型和 Smix 模型的结果,BioCS 作为印尼本地的生物再生剂,具有显著的潜力,可使再生材料的再生率达到 30%。

Effect of biorejuvenator types on microstructure, mechanistic performance, and resilient modulus prediction model of asphalt concrete containing recycled materials in Indonesia

Biorejuvenators are rejuvenating agents produced from sustainable biological raw materials. In this study, a biorejuvenator was used in recycled materials, such as reclaimed asphalt pavement (RAP), to determine its effect on the asphalt binder film thickness (ABFT) and resilient modulus (Smix) of an asphalt concrete wearing course (ACWC) mixture, which was tested at the optimum binder content (OBC). The ABFT was investigated using scanning electron microscopy and the Smix was determined from the asphalt mixture test using UMATTA at test temperatures of 20–40 °C. The asphalt mixture was prepared with RAP (0–30%), pen 60/70, aggregates, and two types of biorejuvenators, namely coconut shell bioasphalt (BioCS) and BitutechRAP (from trees). Furthermore, an Smix model was developed for each mixture type. The ABFT value obtained from the microstructural test results for each mixture corresponded with the minimum ABFT requirements for the adhesion criteria of the asphalt mixture, microstructurally demonstrating that the biorejuvenators worked well to restore the performance of 30%RAP in the ACWC mixture. Both types of biorejuvenators could activate the bitumen of the RAP (RA binder) because they could still produce Smix. The value of Smix produced from the RAP and BioCS mixture was greater than that produced from the RAP and BitutechRAP mixture. In the resulting Smix model, the influential volumetric parameters for ACWC + RAP + BioCS and ACWC + RAP + BitutechRAP were the voids in mineral aggregate and voids in asphalt, respectively. Based on the results of the microstructural, mechanistic, and Smix models, BioCS, as a local Indonesian biorejuvenator, has significant potential to rejuvenate recycled materials up to 30%.
