| یکی از نیازهای طراحی روسازی آسفالتی به روش مکانیستیک – تجربی تعیین مشخصات ویسکوالاستیک مخلوط آسفالتی، از جمله مدول دینامیک و زاویه فاز، است. از آنجایی که آزمایش تعیین مدول دینامیک مخلوط آسفالتی زمانبر و گران است، مدلهایی جهت پیشبینی آن توسط محققین مختلف ارائه شده است. هدف از مطالعه حاضر، بررسی برخی مدلهای پیشبینی موجود جهت تعیین خواص ویسکوالاستیک مخلوطهای آسفالتی داغ، گرم و حاوی خرده آسفالت است. برای این منظور، مخلوطهای آسفالتی با دو نوع دانهبندی (با اندازه سنگدانه بیشینه اسمی 5/9 و 19 میلیمتر) که معرف مخلوطهای لایه رویه و آستر هستند و نیز سه نوع قیر خالص، قیر اصلاحی با افزودنی ساسوبیت و قیر بازیافتی به روش روسازی ممتاز طراحی شدند. آزمایشهای رئومتر برشی دینامیک روی قیرها و تعیین مدول دینامیک روی مخلوطها انجام شدند. مدل تجربی NCHRP 1-40D و مدلهای میکرومکانیکی Hirsch و شکل اصلاح شده آن برای پیشبینی مدول دینامیک مخلوط آسفالتی با دادههای آزمایشگاهی ارزیابی شدند. با بررسی نتایج مشخص شد که مدل تجربی NCHRP با انجام واسنجی نتایج خیلی خوبی دارد (R2>0.95) و پس از آن مدلهای نیمه تجربی و میکرومکانیکی Hirsch اصلاح شده و Hirsch عملکرد مناسبی داشتند. تمامی مدلها در پیشبینی مدول مخلوطهای با دانهبندی ریزتر عملکرد بهتری داشتند. به نظر میرسد که مدلهای مورد بررسی در به حساب آوردن مقاومت ناشی از برخورد سنگدانهها چندان موفق عمل نمیکنند. استفاده از مدلهای پیشبینی مدول برای پیادهسازی روش طراحی جدید در سطح 2 مناسب میباشد. | ||

| One of the requirements for mechanistic-empirical design of asphalt pavement is determining the viscoelastic properties of asphalt mixture, including dynamic modulus and phase angle. Since the dynamic modulus test of asphalt mixture is time consuming and expensive, some prediction models have been proposed by various researchers. The purpose of the present study was to investigate some of the available predictive models to determine the viscoelastic properties of hot, warm and RAP-contained asphalt mixtures. For this aim, asphalt mixtures with two types of gradation (with a nominal maximum aggregate size of 9.5 and 19 mm) representing the mixtures prepared for surface and binder layers, as well as three kinds of bitumen, including neat bitumen, Sasobit-modified bitumen and reclaimed bitumen, were designed according to Superpave method. Dynamic shear rheometer and dynamic modulus tests were performed on the bitumen and the mixtures, respectively. The empirical model of NCHRP 1-40D and micro-mechanical models of Hirsch and its modified form were evaluated for estimating the dynamic modulus of asphalt mixtures using laboratory measurements. It was found that the empirical model of NCHRP performed very well after calibration (R2> 0.95) and then the semi-empirical and micromechanical models of modified Hirsch and Hirsch had a good performance. All models had a better predictability for the modulus of fine graded mixtures. It seems that the considered models are not successful in taking into account the resistance from aggregates interlocking. Application of dynamic modulus prediction models is suitable for implementation of the new design method at Level 2. | ||
