| چکیده | ||
| گسترش شبکه حمل و نقل سبب شده است تا نیاز بیشتری به آنالیز هزینه چرخه عمر و افزایش طول عمر مخلوط‌های آسفالتی احساس شود. به منظور بهبود خصوصیات عملکردی مخلوط‌های آسفالتی روشهای متعددی وجود دارد که یکی از آ‌ن‌ها اصلاح قیر با استفاده از مواد اصلاح کننده است. در سال‌های اخیر با ابداع و گسترش تولید انواع نانومواد توجه خاصی به استفاده از این مواد برای بهبود خواص رئولوژیکی قیر معطوف شده است. بر این اساس، در این پژوهش به بررسی تاثیر نانواکسید مس بر رفتار رئولوژیکی قیر و خصوصیات مکانیکی مخلوط آسفالت پرداخته شده است. از این رو، از آزمایش رئومتر برش دینامیکی برای تعیین مشخصات قیرهای پایه و اصلاح شده در دماهای میانی و بالا و همچنین آزمایش‌های خستگی به روش کشش غیرمستقیم و خزش دینامیکی به منظور بررسی عملکرد مخلوط‌های آسفالتی در مقابل ترک‌خوردگی خستگی و شیارشدگی استفاده شده است. نتایج آزمایش‌های رئولوژیکی قیر نشان می‌دهد که استفاده از نانواکسید مس در 1 و 2 درصد وزن قیر باعث بهبود پارامتر شیارشدگی به ترتیب در قیرهای پیرنشده و پیر شده بین 343-49 و 250-57 درصد و همچنین بهبود پارامتر خستگی در قیرهای پیر شده‌ی بلند مدت از 40-11 درصد شده است. نتایج آزمایش‌های خستگی نشان می‌دهد عمر نمونه‌های حاوی 1 و 2 درصد از این افزودنی در دمای 5 و 20 درجه سانتی‌گراد به ترتیب 16-9 و 31-6 درصد بهبود یابد. همچنین، نتایج پتانسیل شیارشدگی نشان می‌دهد استفاده از 1 و 2 درصد نانواکسیدمس باعث کاهش تغییر شکل ماندگار به ترتیب 35-13 و 37-18 درصد شده است. | ||

| چکیده [English] | ||
| The performance of the asphalt mixture against damage is related to two main factors: external factors and internal factors. External factors are characteristics that are related to environmental factors such as weather conditions, drainage, and traffic. Internal factors are characteristics that are related to the asphalt mixing design, such as the properties and amount of aggregate, the properties and amount of bitumen, the properties of the filler, and the asphalt mixing mix design. Although bitumen has a small volume of asphalt mixture, its role in different temperatures on different failures of asphalt mixture is very important. The growth of the transportation network has led to a special need for the life cycle cost analysis and increase the lifespan of asphalt mixtures. There are several ways to improve the performance of asphalt mixtures, one of which is bitumen modification using modifiers. In recent years, with the invention and expansion of the production of nanomaterials, special attention has been paid to the use of nanomaterials to improve the rheological properties of bitumen. Accordingly, this study evaluates the effect of copper nano oxide on the rheological behavior of bitumen and the mechanical properties of the asphalt mixture. Therefore, the dynamic shear rheometer is used to determine the specifications of bitumens at medium and high temperatures, as well as fatigue and dynamic creep tests to investigate the performance of asphalt mixtures against fatigue cracking and rutting. The results of bitumen rheological experiments show that the use of copper nano oxide at 1 and 2 percent by weight of bitumen improves the rutting parameter in unaged and short-term aged bitumen from 49-343 and 57-257 percent, respectively, and also improves the fatigue parameter in long-term aged bitumen from 11-40 percent. The results of fatigue tests show that the fatigue life of samples containing 1 and 2 percent of this additive at 5 and 20 °C will improve by 9-16 percent and 6-31 percent, respectively. Also, the results of the rutting potential show that the use of 1 and 2 percent of nano oxide has reduced the permanent deformation change of 13-35 and 18-18 percent, respectively. | ||
