摘要

摘要由于高质量骨料供应的枯竭,在路面结构层中加入少量软质材料(如泥)已成为必要。本研究旨在探讨胶凝稳定路面材料(CSMM)的力学特性,为路面力学设计提供参考。测试包括无侧限抗压强度、浸水状态下的加州承载比、弯曲强度、间接抗拉强度、耐久性和收缩行为,通过全面的实验室调查程序。在这次调查中,收集的样本来自印度东部的比哈尔邦。各种力学特性之间的关系已经发展为路面分析。为了研究路面结构的性能,按照标准获得了这些性能。在研究结果的基础上,讨论了强度和收缩特性在决定CSMM作为道路基层和基层应用的可接受性方面的有效性。关键词:机械设计;自收缩;最终干燥收缩披露声明作者未报告潜在利益冲突。

Mechanical characterisation of cementitiously stabilised moorum for use as structural layers in paving road construction
AbstractDue to the depletion of supplies for high-quality aggregates, it has become necessary to incorporate marginally soft materials like moorum in pavement structural layers. This study aimed to investigate the mechanical characteristics of cementitiously stabilised moorum materials (CSMM), which would be relevant during the mechanistic design of pavements. The tests includes the unconfined compressive strength, california bearing ratio in a soaked state, flexural strength, indirect tensile strength, durability and shrinkage behaviour through a comprehensive laboratory investigation procedure. In this investigation, the collected moorum sample was from Bihar, the eastern state of India. Relationships between various mechanical characteristics have been developed for pavement analyses. The properties are achieved as per standards to study the behaviour of the pavement structures. Based on the research findings, the effectiveness of the strength and shrinkage characteristics in determining the acceptability of CSMM as a road base and subbase applications have been discussed.KEYWORDS: Mechanistic designIDTMORautogenous shrinkageultimate drying shrinkage Disclosure statementNo potential conflict of interest was reported by the author(s).

期刊介绍: The international journal Road Materials and Pavement Design welcomes contributions on mechanical, thermal, chemical and/or physical properties and characteristics of bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, geo-composites, new and innovative materials, as well as mix design, soil stabilization, and environmental aspects of handling and re-use of road materials. The Journal also intends to offer a platform for the publication of research of immediate interest regarding design and modeling of pavement behavior and performance, structural evaluation, stress, strain and thermal characterization and/or calculation, vehicle/road interaction, climatic effects and numerical and analytical modeling. The different layers of the road, including the soil, are considered. Emerging topics, such as new sensing methods, machine learning, smart materials and smart city pavement infrastructure are also encouraged. Contributions in the areas of airfield pavements and rail track infrastructures as well as new emerging modes of surface transportation are also welcome.
