| چکیده | ||
| بازیافت و استفاده مجدد از مصالح در دهههای اخیر مورد توجه محققین قرار گرفته است. امروزه، مسائل زیست‌محیطی به دلیل محدودیت منابع و همچنین افزایش هزینه مواد جدید بسیار حائز اهمیت شده است. از آنجا که بیشتر راههای موجود در ایران از نوع آسفالتی میباشند، استفاده از تراشه آسفالتی و مصرف کمتر مصالح جدید میتواند به‌عنوان یک راه‌حل سازگار با محیط‌زیست مطرح گردد. در بازیافت تراشههای آسفالتی، نگرانیهایی در ارتباط با ترک‌های دمای کم وجود دارد. هدف از این پژوهش، بررسی خواص ترک دمای کم مخلوطهای حاوی تراشه آسفالتی، به همراه مواد افزودنی دیگر، جهت معرفی مخلوطی با خصوصیات عملکردی معادل مخلوط آسفالتی پایه میباشد. به این منظور، دو درصد مختلف برای نمونههای آسفالتی (25% و 50% تراشه آسفالتی) در نظر گرفته شد. به‌منظور بهبود خواص چسبندگی آن‌ها، افزودن جوانساز سایکلوژن (10% وزنی قیر تراشه به عنوان درصد بهینه) و برای بهبود مقاومت مخلوط در برابر ترک‌خوردگی، پودر لاستیک (10% وزنی قیر جدید) در نظر گرفته شد. خواص مخلوطها با آزمایش استقامت کششی غیرمستقیم و آزمایش خمش نیم‌استوانه بررسی شد. بازشدگی دهانه ترک در حین آزمایش خمش نیم‌استوانه به کمک تصویربرداری مشخص شد. مطابق این آزمایش، افزودن تراشه آسفالتی به نمونه پایه باعث کاهش انرژی شکست می‌شود. اما افزودن جوانساز و پودر لاستیک به نمونههای بازیافتی، خواص مخلوط در برابر رشد ترک را بهبود میدهد. طبق نتایج، مخلوطهای آسفالتی حاوی تراشه آسفالت به همراه افزودنیها، عملکردی برابر و یا حتی بهتر از مخلوط آسفالتی پایه داشتند. همچنین، شاخص ترکیبی انرژی شکست– بازشدگی دهانه ترک میتواند به عنوان معیار مناسبی جهت بررسی تأثیر تراشه آسفالتی و افزودنی‌های جوانساز و پودر لاستیک در نمونههای مخلوط آسفالتی استفاده شود. | ||

| چکیده [English] | ||
| Recycling and reusing materials have received much attention from researchers in recent decades. Today, environmental issues have become very important due to the limitation of available resources as well as the increase in the cost of new materials. Since most of the existing roads in Iran have flexible pavements, using reclaimed asphalt pavement (RAP) and using fewer new materials can be considered an environmentally friendly solution. In recycling asphalt pavements, there is a major concern related to low-temperature cracking. The purpose of this research is to investigate the low-temperature cracking properties of asphalt mixtures containing RAP along with other additives to introduce a mixture with performance characteristics equivalent to the new asphalt mixture. For this purpose, asphalt mixtures with two different contents of RAP (25% and 50%) were considered. Also, to improve their adhesion properties, the addition of a rejuvenator (10% by weight of RAP binder as the optimal percentage) and to improve the resistance of the mixture against cracking, crumb rubber (10% by weight of new binder) was considered. An indirect tensile strength test and a semi-circular bending test (SCB) were performed to investigate the properties of the mixtures. Also, the crack mouth opening displacement (CMOD) during the SCB test was measured through imaging. According to the SCB test, adding RAP to the base sample reduces the fracture energy. But adding rejuvenator and crumb rubber to the recycled samples improves the properties of the mixture against crack growth. The results showed that the asphalt mixtures containing RAP and additives, according to the tests used in this research, presented equal or even better performance than the new asphalt mixture. Also, the combined index of fracture energy - CMOD can be used as a suitable criterion to investigate the effect of RAP, rejuvenator and crumb rubber in asphalt mixture. | ||
