| چکیده | ||
| در این تحقیق اثر پلیمر پسماند پولی بوتادین رابر (PBR)، در ارزیابی عملکردی مخلوط‌های آسفالتی حاوی مصالح خرده آسفالتی (RAP) بررسی شده است. درصدهای مختلف RAP شامل 20، 30 و 50 درصد برای تهیه مخلوط آسفالتی انتخاب شدند. برای تهیه قیر پلیمری، قیر 60/70 با 5 درصد وزنی از پلیمر پسماند PBR مخلوط شده و به‌عنوان قیر تازه در مخلوط‌های آسفالتی حاوی RAP اضافه شد. در این مطالعه آزمایش‌های تیرچه خمشی چهار نقطه‌ای برای ارزیابی رفتار خستگی مخلوط‌ها، آزمایش لاتمن اصلاح شده برای ارزیابی حساسیت رطوبتی و آزمایش ویل تراک هامبورگ برای ارزیابی مقاومت شیارشدگی مخلوط‌های آسفالتی حاوی RAP استفاده شد. نتایج نشان داد که وجود پلیمر ضایعاتی مورداستفاده باعث شده که مقاومت خستگی مخلوط‌های آسفالتی حاوی 20 و 30 درصد RAP نسبت به مخلوط کنترل افزایش قابل‌توجهی داشته باشد. همچنین استفاده از این پلیمر می‌تواند در مخلوط‌های آسفالتی با درصد RAP کمتر از 50 درصد (حدوداً 40 درصد) بدون هیچ‌گونه نگرانی از کاهش مقاومت خستگی آسفالت استفاده کرد. همچنین نتایج نشان داد که با استفاده از قیر پلیمری در مخلوط‌های آسفالتی حاوی RAP ، مقاومت مخلوط‌ها در برابر حساسیت رطوبتی افزایش قابل‌توجهی نسبت به مخلوط کنترل داشته است. نتایج آزمایش ویل تراک هامبورگ هم نشان داد که ترکیب مصالح RAP و قیر پلیمری توانسته است، عمق شیار را تا 70 درصد نسبت به مخلوط کنترل کاهش دهد. | ||

| چکیده [English] | ||
| In this research, the effect of waste polybutadiene rubber (PBR) has been investigated in the performance evaluation of asphalt mixtures containing RAP. Different percentages of RAP, including 20, 30, and 50%, were selected to prepare the asphalt mixture. To prepare polymer-modified bitumen, bitumen 60/70 was mixed with 5% by weight of waste PBR polymer and then added to asphalt mixtures containing different percentages of RAP. In this study, four-point bending beam, modified Lottman and Hamburg Wheel-Track tests were performed to evaluate the fatigue behavior, moisture susceptibility, and the rutting resistance of asphalt mixtures containing RAP, respectively. The results showed that the presence of utilized waste polymer significantly improved the fatigue behavior of asphalt mixtures containing 20 and 30% RAP compared to the control mixture. Also, the use of this polymer can be used in asphalt mixtures with a RAP percentage of less than 50% (about 40%) without any concern about reducing the fatigue resistance of asphalt. Furthermore, the results showed that by using waste PBR in asphalt mixtures containing RAP, the resistance of the mixtures against moisture susceptibility has increased significantly compared to the control mixture. The results of the Hamburg Wheel-track test also showed that the combination of RAP materials and used waste polymer could reduce the rut depth by 70% in comparison with the control mixture. | ||
