| با توجه به مزایای مهم اقتصادی و زیستمحیطی مخلوط آسفالت کمانرژی و نیاز به شناخت و بررسی بیشتر این آسفالت به دلیل اندک تحقیقات صورت گرفته، در این مقاله، به ارزیابی و بررسی خصوصیات ویسکوالاستیک این نوع مخلوط آسفالتی با استفاده از آزمایش مدول دینامیک پرداخته شد. بهدلیل ضعف مکانیکی مخلوطهای آسفالتی مزبور و با عنایت به ماهیت زیستمحیطی این نوع آسفالت، افزودنی سازگار با محیطزیست جهت اصلاح آن در اولویت قرار گرفت. از اینرو، پودر لاستیک در سه سطح 10، 15 و 20 درصد وزن قیر جهت اصلاح نمونهها انتخاب گردید. نمونههای آسفالتی شاهد و اصلاح شده مطابق با روش سوپرپیو طراحی و متراکم شدند و جهت تعیین خصوصیات ویسکوالاستیک آنها در دماها و فرکانسهای مختلف تحت آزمایش مدول دینامیک قرار گرفتند. منحنی جامع مخلوطهای آسفالتی نشان داد که در دمای زیاد (فرکانس کم) بیشترین مدول دینامیک متعلق به مخلوط آسفالتی کمانرژی با 15 درصد پودر لاستیک است. لذا، این مخلوط دارای بیشترین مقاومت شیارشدگی نسبت به سایر نمونهها است. از طرفی، مقایسه منحنی جامع مخلوطهای آسفالتی در دمای کم (فرکانس زیاد) به ترتیب نشاندهنده کم بودن سفتی نمونههای آسفالت کمانرژی فاقد افزودنی و آسفالت کمانرژی دارای 15 درصد افزودنی و مقاومت آنها در برابر ترکخوردگی بود. همچنین، ارزیابی خصوصیات ویسکوالاستیک نمونههای آزمایش مؤید این حقیقت بود که بیشترین خاصیت الاستیک متعلق به نمونه آسفالت کمانرژی اصلاح شده با ۱۵ درصد پودر لاستیک و ویسکوزترین مخلوط، نمونه آسفالتی داغ میباشد. | ||

| چکیده [English] | ||
| Considering the important economic and environmental benefits of low energy asphalt mixture and the need to know and study more about this asphalt due to little research, in this article, the linear viscoelastic properties of this type of asphalt are evaluated using dynamic modulus test. Due to the mechanical weakness of this asphalt mixture and considering its environmental nature, an additive compatible with the environment was selected to modify it. Therefore, crumb rubber in three levels of 10, 15 and 20% by weight of asphalt binder was used to modify the samples. Controlled and modified asphalt samples were designed and compacted according to the superpave method and were tested to determine the dynamic modulus and their viscoelastic properties at different temperatures and frequencies. The master curve of asphalt mixtures showed that at high temperature (low frequency) the highest dynamic modulus belongs to low energy asphalt mixtures with 15% rubber powder. Therefore, this mixture has the highest rutting strength compared to other mixtures. On the other hand, comparison of the master curve of asphalt mixtures at low temperature (high frequency) showed low stiffness of low energy asphalt samples without additive and low energy asphalt with 15% additive and their resistance to cracking, respectively. Evaluation of the viscoelastic properties of the test specimens also confirmed the fact that the highest elasticity belonged to the low-energy asphalt sample modified with 15% crumb rubber and the most viscous mixture was the hot asphalt sample. | ||
