| چکیده | ||
| با توسعه شبکه حمل و نقل، بخش زیادی از درآمد های کشور ها صرف تعمیر و نگهداری راه ها می شود. با توجه به معایب روسازی آسفالتی نسبت به روسازی بتنی و افزایش هزینه قیر، استفاده از روسازی بتنی توجیه اقتصادی پیدا کرده است. یکی از انواع روسازی بتنی، روسازی بتن غلتکی می باشد. از مهمترین عوامل تاثیرگذار بر مقاومت روسازی بتن غلتکی، نوع و کیفیت سنگدانه های آن است. سابقه کاربرد روسازی بتن غلتکی عمدتاً جهت جاده ها و یا روسازی های با سرعت ترافیک پایین بوده است هرچند که امروزه با پیشرفت تکنولوژی و ساخت فینیشرهای با کارایی بالاتر و قدرت تراکم بیشتر امکان استفاده از آن برای سرعت های بالاتر فراهم شده است. در این تحقیق به بررسی امکان استفاده از سنگدانههای سرامیک ضایعاتی به منظور جایگزینی با سنگدانه های طبیعی در بتن غلتکی پرداخته شد. استفاده از مواد ضایعاتی نه تنها باعث کاهش مواد ضایعاتی و بازیافت مناسب آن ها می گردد بلکه با کاهش مصرف مصالح طبیعی نیز به اقتصاد ساخت و محیط زیست کمک خواهد کرد. نتایج آزمایش ها نشان می دهد که مقاومت فشاری و کششی بتن غلتکی در سن 28 روز با جایگزینی سنگدانه های سرامیکی به عنوان ریز دانه باعث افزایش چشمگیر مقاومت فشاری و کششی به ترتیب تا 39 و 2/5 مگاپاسکال میشود. همچنین استفاده از سنگدانه های سرامیکی به عنوان درشت دانه هم، مقاومت فشاری وکششی بتن غلتکی را در مقایسه با نمونه شاهد بهبود می بخشد. نتایج این پژوهش گویای اهمیت کاربرد سنگدانه های سرامیکی جهت بهبود عملکرد بتن غلتکی می باشد. در نهایت به دلیل استفاده از سنگدانه های سرامیکی در بتن وزن مخصوص آن کاهش و جذب آب آن به دلیل جذب آب بیشتر سنگدانه های سرامیکی افزایش یافته است. | ||

| چکیده [English] | ||
| With the development of the transportation network, much of the country's revenue is spent on road maintenance. Due to the disadvantages of asphalt pavement over concrete pavement and increased bitumen cost, the use of concrete pavement has made economic justification. One type of concrete pavement is roller concrete pavement. One of the most important factors affecting pavement strength of roller concrete is the type and quality of its aggregates. The history of roller concrete pavement use has been mainly for low-speed roads or pavements, although today with the advancement of technology and the development of higher-performance finishers and higher compressive strength, it has been possible to use them at higher speeds. In this study, the possibility of using scrap ceramic aggregates for replacement with natural aggregates in roller concrete was investigated. The use of waste materials will not only reduce waste and recycle it properly but will also help to reduce the consumption of natural materials in the construction and environment economy. Experiments on compressive strength, tensile strength, specific gravity and water absorption were performed on roller concrete specimens. Experimental results show that the compressive and tensile strength of roller concrete at 28 days of age by the replacement of ceramic aggregates as fine grains significantly increases the compressive and tensile strengths by 39 and 5.2 MPa, respectively. The use of ceramic aggregates as coarse grains also improves the compressive and tensile strength of the roller concrete compared to the control. The results of this study indicate the importance of using ceramic aggregates to improve the performance of roller concrete. Finally, due to the use of ceramic aggregates in concrete, its specific weight has decreased and its water absorption has increased due to the absorption of more ceramic aggregates. | ||
