Abstract

In this article by adding different percentages of carbon fiber with high strength and doing the necessary Marshall tests, it was observed that the Marshall Resistance and its Flow increased. Due to their armed properties, the carbon fibers have a positive effect on Marshall Resistance. According to the results, in-creasing the percentage of fibers, reduces the resistance, so that the resistance of the sample containing 1.5% of carbon fiber is almost 32% more than the resistance of the sample without fiber. According to the results, the increased resistance compared to the previous researches and other fibers stems from the kind of fiber used in it and its high resistance. After increasing the fiber percentage to 3, a 12% decrease in the resistance was seen. On the other hand, by changing the percentage of the fibers added to the aggregates, the Flow will change, so that the sample containing 3% of fiber is almost 189% more Flow than the base sample. The economic analysis was used for a three-lane road. The results showed that economically speaking, due to their high price, these types of fibers are recommended to be used in restricted and optimal areas.

高强度碳纤维对热拌沥青（HMA）影响的经济技术研究

本文通过添加不同比例的高强度碳纤维，并进行必要的马歇尔试验，观察到马歇尔阻力及其流动性的增加。由于其武装性能，碳纤维对马歇尔阻力有积极影响。根据结果，随着纤维百分比的增加，电阻降低，因此含有1.5%碳纤维的样品的电阻几乎比没有纤维的样品高32%。结果表明，与以前的研究和其他纤维相比，电阻的增加源于其中使用的纤维种类及其高电阻。在将纤维百分比增加到3之后，可以看到电阻降低了12%。另一方面，通过改变添加到聚集体中的纤维的百分比，Flow将发生变化，因此含有3%纤维的样品的Flow几乎比基础样品多189%。经济分析用于一条三车道道路。结果表明，从经济角度讲，由于这些类型的纤维价格高，建议在限制和最佳区域使用。

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.
