چکیده

یکی از مهمترین پیشرفت‌ها در تکنولوژی راهسازی استفاده از رویه‌های بتنی می‌باشد. از این رویه‌ها در راه‌هایی که به حداکثر عملکرد و کمترین تعمیرات در زمان بهره ورداری نیاز دارند، استفاده می‌گردد. از طرفی در دهه‌ی اخیر به منظور بهبود عملکرد بتن، استفاده از کامپوزیت‌های سیمانی و الیاف رایج شده است. در این تحقیق به بررسی نقش الیاف‌های فولادی و پلی پروپیلن در بهبود رفتار رویه‌های کامپوزیتی سیمانی خود تراکم پرداخته شده است. برای این منظور، تعداد 127 عدد نمونه مکعبی، استوانه‌ا‌ی و دیسکی در 11 طرح اختلاط مختلف ساخته شد. همچنین نمونه‌های خمشی دو لایه در 17 طرح اختلاط مختلف حاوی الیاف‌های فولادی، پلی پروپیلن و ترکیبی از آن‌ها ساخته شده است. بر روی نمونه‌ها، آزمایشات فشار، کشش برزیلی، ضربه‌ی وزنه افتان، جذب آب نیم ساعته و 72 ساعته وخمش سه نقطه‌ای مطابق با ضوابط نشریه 731 انجام گرفت. نتایج نشان دهنده‌ی تاثیر مطلوب‌تر الیاف فولادی نسبت به الیاف پلی پروپیلن بر روی خصوصیات مکانیکی و ضربه‌ای نمونه‌ها می‌باشد.

چکیده [English]

One of the most important advances in road construction technology is the use of concrete pavements. These pavements are used in roads that require maximum performance and minimum repairs at the time of use. On the other hand, in recent decades, the use of cementitious composites and common fibers Has become popular to improve concrete performance. In this research, the role of steel and polypropylene fibers in improving the behavior of self-compacting cementitious composites pavements has been investigated. For this purpose, 127cubes specimens, cylinders and discs were made in 11 different mixing design.Two-layer flexural specimens were made in 17 different mixing designs containing steel fibers, polypropylene and a combination of them. On specimens, compressive tests, splitting test, drop weigth impact test and water absorption for half an hour and 72 hours and three point flexural test in accordance with the regulations of the 731 code have been done. the results showed that the more favorable effect of the steel fibers than the polypropylene fibers on the mechanical and impact properties the specimens.
