Abstract

Very Thin Asphalt Overlay (VTAO) has been introduced as an alternative to traditional thick overlays, seal coats, and micro-surfacings. Nonetheless, there are some challenges that still remain regarding the application of VTAOs (such as mixture type, cohesiveness, wear resistance, cracking and durability), particularly in heavy traffic urban areas. Therefore, this paper presents an extensive comparative evaluation of the mechanical performance, durability and safety issues (cohesiveness, adhesiveness, ageing, cracking, plastic deformation, permeability, macrotexture, skid and wear resistance, and fuel resistance) of a VTAO (20 mm thick) and a high performance BBTM 11B (35 mm thick), commonly used as an open-graded mixture for pavement overlays. The results demonstrated that VTAO is an appropriate material for urban pavements as it provides good durability and resistance to the propagation of defects. Nonetheless, further studies are required to improve its behavior under distresses related to plastic deformations and safety properties.

超薄沥青覆盖层作为城市道路可持续修复策略的力学性能评价

超薄沥青覆盖层(VTAO)作为传统的厚覆盖层、密封层和微表面的替代方案被引入。尽管如此，VTAOs的应用仍然存在一些挑战(例如混合物类型、黏结性、耐磨性、开裂性和耐久性)，特别是在交通繁忙的城市地区。因此，本文对VTAO(20毫米厚)和高性能BBTM 11B(35毫米厚)的机械性能、耐久性和安全性问题(粘结性、黏附性、老化性、开裂性、塑性变形、渗透性、宏观结构、防滑和耐磨性以及耐燃油性)进行了广泛的比较评估，这两种材料通常用作路面覆盖层的开级配混合料。结果表明，VTAO具有良好的耐久性和抗缺陷扩展能力，是一种适合用于城市路面的材料。然而，需要进一步的研究来改善其在与塑性变形和安全性能有关的灾难下的行为。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
