Abstract

Nanomaterial have been considered as one of the new additives by researchers for use in asphalt pavement. In this study, economic analysis along with technical analysis of the effect of different percentages of Nano carbon black on a 1 km long road was evaluated. The results showed that the addition of Nano carbon black to the asphalt mixture in low percentages reduced the Marshall stability due to the lack of proper bonding between bitumen and Nano carbon black. By increasing the percentage of Nano carbon black in the asphalt mix, Marshall Stability increased. Also, Nano carbon black has clearly shown potential for improving the permanent deformation resistance of the modified asphalt mixture. During the Marshall Quotient test, more than two times increase in rutting resistance has been observed by adding more than 10% Nano carbon black to the asphalt mixture. On the other hand, the results of economic analysis showed that the project has become uneconomic in different percentages; however, due to the positive effect of adding Nano carbon black on the technical properties of asphalt mixtures, it is recommended that Nano carbon black be used sparingly in areas where the pavement suffers from a lack of load-bearing capacity.

纳米炭黑对沥青混合料影响的技术经济研究

纳米材料被研究人员认为是一种新型的沥青路面添加剂。在本研究中，对不同百分比的纳米炭黑对1公里长道路的影响进行了经济分析和技术分析。结果表明，在沥青混合料中加入低百分比的纳米炭黑，由于沥青与纳米炭黑之间缺乏适当的结合，降低了马歇尔稳定性。通过增加纳米炭黑在沥青混合料中的百分比，马歇尔稳定性提高。此外，纳米炭黑在提高改性沥青混合料的永久变形抗力方面也显示出了明显的潜力。在马歇尔商试验中，通过在沥青混合料中添加10%以上的纳米炭黑，可以观察到抗车辙性增加了两倍以上。另一方面，经济分析结果表明，该项目在不同的百分比上都变得不经济；然而，由于添加纳米炭黑对沥青混合料的技术性能有积极影响，建议在路面缺乏承载能力的地区谨慎使用纳米炭黑。

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.
