Abstract

Marshall Test is one of the tests used for asphalt mixture. This test has six parameters, including stability, unit weight, flow, void in mineral aggregate, voids in total mix, and voids filled with asphalt. Further, the additional cost of various additives to the asphalt mixture for building one kilometer of the road is a negative parameter. However, using additives improves the technical characteristics of the asphalt mixture. Therefore, making a proper choice among the alternatives would be a hard task. This paper tries to provide an appropriate method for mixing the design of asphalt mixtures to select the best alternative by considering all technical criteria. For this purpose, the concordance analysis method, which is one of the compensation models of the Multi-Criteria Decision-Making (MCDM), was used. The results showed that the concordance analysis method using a pairwise comparison strategy combines the different criteria to prioritize alternatives and to propose the best alternative. Therefore, this method can be used as a superior method for mixing the design of asphalt mix compared to conventional methods.

多准则决策在沥青混合料合理配比中的应用

马歇尔试验是用于沥青混合料的试验之一。该试验有六个参数，包括稳定性、单位重量、流量、矿物骨料中的空隙、总混合料中的空隙和沥青填充的空隙。此外，用于修建一公里道路的沥青混合料的各种添加剂的额外成本是一个负参数。然而，使用添加剂改善了沥青混合料的技术特性。因此，在备选方案中作出适当选择将是一项艰巨的任务。本文试图为沥青混合料的混合设计提供一种合适的方法，通过考虑所有技术标准来选择最佳的替代方案。为此，使用了作为多准则决策（MCDM）补偿模型之一的一致性分析方法。结果表明，使用成对比较策略的一致性分析方法结合了不同的标准来确定备选方案的优先级并提出最佳备选方案。因此，与传统方法相比，该方法可以作为一种优越的沥青混合料混合设计方法。

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
