چکیده

چکیده در این تحقیق به ارزیابی تأثیر استفاده از افزودنی‌های گریپر، تراگریپ و وتمول-950 به‌عنوان مواد افزودنی ضد عریان شدگی بر خواص مکانیکی مخلوط‌های آسفالتی داغ پرداخته‌شده است. بدین منظور از آزمایش‌های مکانیکی مختلف نظیر خزش دینامیکی، آزمایش مدول برجهندگی در دمای 25 درجه‌ی سانتی‌گراد، آزمایش کشش غیرمستقیم و آزمایش خمش نیم ‌دایره‌ای در دمای 25 درجه‌ی سانتی‌گراد استفاده گردید. نتایج آزمایش‌های مکانیکی نشان داد که همه‌ی افزودنی‌های مورداستفاده در این تحقیق مقاومت در برابر حساسیت رطوبتی، مقاومت در برابر شیار شدگی و مقاومت در برابر ترک‌خوردگی مخلوط‌های آسفالتی را افزایش دادند. به‌طوری‌که مخلوط آسفالتی حاوی افزودنی تراگریپ نسبت به بقیه‌ی افزودنی‌های مورداستفاده در این تحقیق، با افزایش 43 درصدی مقاومت در برابر شیار شدگی و 6/49 درصدی مقاومت در برابر ترک‌خوردگی بیشترین مقاومت را در برابر ترک‌خوردگی و شیار شدگی از خود نشان داده است. همچنین مخلوط آسفالتی حاوی وتمول-950 با 25 درصد افزایش مقاومت در برابر خرابی رطوبتی بیشترین مقاومت در برابر حساسیت رطوبتی را از بین افزودنی‌های مختلف این تحقیق نشان داده است. از طرف دیگری نتایج آنالیز همبستگی بین نتایج آزمایش‌های عملکردی مخلوط‌های آسفالتی نشان داد که بین برخی آزمایش‌های انجام‌ شده همبستگی و ارتباط بیشتری وجود دارد. به‌طوری‌که ضریب همبستگی بین پارامتر نسبت مقاومت کششی غیرمستقیم و نسبت مدول برجهندگی در حالت تر و خشک (TSR و RMR) با 974/0 بیشترین همبستگی را بین پارامترهای مختلف آزمایش‌های عملکردی دارد.

چکیده [English]

In this study, the effect of using GRIPPER, TeraGrip and WETMUL-950 additives as anti-stripping additives on the mechanical properties of hot mix asphalt has been investigated. For this purpose, various mechanical tests such as dynamic creep at 54.4°C, resilient modulus test at 25°C, indirect tensile test and semi-circular bending test at 25°C were used. The results of mechanical tests showed that all additives used in this study increased the moisture damage, rutting and crack resistance of asphalt mixtures. Asphalt mixture containing TeraGrip compared to other additives used in this study showed the highest resistance to rutting and cracking, resulting in 43% increase in rutting resistance and 49.6% in crack resistance. Moreover, asphalt mixture containing WETMUL-950 showed 25% increase in moisture damage resistance (i.e., the highest resistance to moisture sensitivity among the various additives used in this study). On the other hand, the results of correlation analysis between the results of performance tests of asphalt mixtures showed that there was more correlation and relation between the performed tests. So that the correlation coefficient between the parameter of indirect tensile strength ratio and resilient modulus ratio under wet and dry conditions (TSR and RMR) with 0.974 has the highest correlation between different parameters of mechanical tests.
