Abstract

The objective of this study was to improve the performance of flexible pavement through suitable aggregate gradation. Thus, initially, the dynamic modulus of asphalt mixtures |E*| for different aggregate gradations were predicted, and suitable aggregate gradation was determined. Then the performance of three different pavement structures for two aggregate gradations (Mid and Suitable), using AASHTOWare Pavement ME Design 2.5. 5, were evaluated for local conditions of Izmir, Turkey. The analysis result revealed that using suitable values compared to middle values increased the |E*| and improved the rutting and fatigue resistance of all pavement structures for any traffic levels. The output of this study can be used as a guide for hot mixed asphalt mix design and pavement design based on Mechanistic-Empirical Pavement Design Guide as well.

通过合适的骨料级配改善柔性路面性能

本研究的目的是通过合适的骨料级配来改善柔性路面的性能。因此，初步预测了不同骨料级配下沥青混合料的动态模量|E*|，并确定了合适的骨料级配。然后使用AASHTOWare pavement ME Design 2.5对两种骨料级配(中等和适宜)下的三种不同路面结构进行性能分析。5，对土耳其伊兹密尔的当地情况进行了评估。分析结果表明，与中间值相比，选择合适的值可提高所有路面结构在任何交通水平下的车辙性能和抗疲劳性能。本文的研究成果可为热拌沥青混合料的设计和基于力学-经验路面设计指南的路面设计提供指导。

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
