چکیده
One of most important behaviors expected from bitumen is elastic behavior. More elasticity in bitumen and hot mix asphalt leads to less distress and deterioration in asphalt. Bitumen as a visco-elastic material has elastic behavior and viscose behavior. To be desirable, the portion of bitumen elastic behavior must be more than its viscose behavior. To enhance the properties of bitumen different additives are added to it. In this study crumb reclaimed rubber (CRR) as a polymer and filler was added to bitumen to modify and increase its elasticity. It was seen that CRR is very effective on performance of bitumen; and by different performed tests it was obtained that, this additive is able to rise and improve the amount and portion of elastic behavior of bitumen. Elastic recovery test and rheological assessing was done to investigate the amount and quality of effects of CRR on bitumen properties.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
