Recycled Pavement(再生路面)研究综述
Recycled Pavement 再生路面 - The results demonstrated that the maximum use of 20% RAP binder (33% RAP material) was allowed in the recycled pavement using nanomodified binder. [1] In recent years, researchers have generally paid attention to two main approaches: the application of rubber modified asphalt and the performance enhancement of recycled pavement. [2] Moreover, under the condition of ensuring the road performance of recycled pavement, with the increasing proportion of reclaimed asphalt pavement, the environmental benefit of recycled pavement is higher. [3] In Spain, in the absence of tests specifically designed to determine the behavior of recycled pavements stabilized with cement, these materials are treated as soil-cement or cement-bound granular material. [4] Considering that the recycled structure (FA and AC overlay) is based on a remaining cement bound material (CBM) layer, the recycled pavement can be characterized as “non-conventional”. [5]结果表明,使用纳米改性粘合剂的再生路面允许最大使用 20% RAP 粘合剂(33% RAP 材料)。 [1] 近年来,研究人员普遍关注两种主要途径:橡胶改性沥青的应用和再生路面的性能增强。 [2] 而且,在保证再生路面路面性能的情况下,随着再生沥青路面比例的增加,再生路面的环境效益更高。 [3] 在西班牙,由于没有专门设计用于确定用水泥稳定的再生路面的性能的测试,这些材料被视为土壤水泥或水泥结合的颗粒材料。 [4] 考虑到再生结构(FA 和 AC 覆盖层)基于剩余的水泥粘合材料(CBM)层,再生路面可以被描述为“非常规”。 [5]
Cold Recycled Pavement 冷再生路面
Asphalt-treated cold recycled pavements, including cold in place recycling, full depth reclamation, and cold central plant recycling, are becoming popular rehabilitation options because they are economical, sustainable, and provide good performance. [1] In addition, the study presents a framework for the design and analysis of cold recycled pavement layers and a method to integrate the plasticity behavior of partially-bonded and unbounded layers for pavement evaluation. [2] The proposed cold recycled pavement evaluation indexes were divided into three fuzzy grades of evaluation indexes and subindexes. [3] The characterization of cold recycled pavement materials at an early stage of their life, right after compaction, is difficult, especially if classical tests are used. [4] Meanwhile, the National Center for Asphalt Technology also constructed four cold recycled pavement sections in the field. [5]沥青处理的冷再生路面,包括现场冷再生、全深度再生和中央工厂冷再生,正成为流行的修复选择,因为它们经济、可持续并提供良好的性能。 [1] 此外,该研究提出了一个设计和分析冷再生路面层的框架,以及一种整合部分粘合层和非粘合层的塑性行为以进行路面评估的方法。 [2] 提出的冷再生路面评价指标分为三个模糊等级的评价指标和子指标。 [3] 冷再生路面材料在其生命的早期阶段(即压实后)的表征是困难的,尤其是在使用经典测试的情况下。 [4] 同时,国家沥青技术中心还在现场建设了四个冷再生路面段。 [5]

Furthermore, easily recycled pavement materials, and safe and efficient pavement construction are also important areas for development in road engineering. [1] Overall, a procedure was proposed to select the appropriate dosage and type of rejuvenator for polymer modified binders toward engineering durable and long-lasting recycled pavement materials. [2] The characterization of cold recycled pavement materials at an early stage of their life, right after compaction, is difficult, especially if classical tests are used. [3] Key words: Soil-cement stabilization, road pavement, recycled pavement material, unconfined compressive strength, soil particle size distribution. [4] use of recycled pavement materials, stabilization of locally available poor-quality materials, and use of reinforced pavement. [5]此外,易于回收的路面材料和安全高效的路面施工也是道路工程发展的重要领域。 [1] 总体而言,提出了一种程序来选择聚合物改性粘合剂的合适剂量和类型的再生剂,以设计耐用和持久的再生路面材料。 [2] 冷再生路面材料在其生命的早期阶段(即压实后)的表征是困难的,尤其是在使用经典测试的情况下。 [3] 关键词:土壤水泥稳定化,路面,再生路面材料,无侧限抗压强度,土壤粒度分布。 [4] 使用再生路面材料,稳定当地可用的劣质材料,以及使用加筋路面。 [5]

In addition, the study presents a framework for the design and analysis of cold recycled pavement layers and a method to integrate the plasticity behavior of partially-bonded and unbounded layers for pavement evaluation. [1] Direct shear tests and gyratory compaction were used to evaluate the bond strength between the old and recycled pavement layers and the workability of the regenerated mixtures under the various heating conditions, respectively. [2]此外,该研究提出了一个设计和分析冷再生路面层的框架,以及一种整合部分粘合层和非粘合层的塑性行为以进行路面评估的方法。 [1] 直接剪切试验和回转压实分别用于评估旧路面和再生路面层之间的粘合强度以及再生混合物在各种加热条件下的工作性。 [2]
