چکیده

امروزه با رشد جمعیت و افزایش آلودگی آب‌وهوا، موضوع تصفیه آب و استفاده از نانومواد مورد توجه همگانی قرارگرفته است. با توجه به اینکه مسائل محیط­زیستی نظیر کاهش آلاینده‌های موجود در محیط‌های متخلخل نظیر آسفالت از اهمیت برخوردار است، لذا هدف این پژوهش تعیین آزمایشگاهی نقش نانومواد بر بهبود قابلیت انعطاف‌پذیری و حذف آلودگی در آسفالت متخلخل در رواناب سطحی شهری بود. بدین منظور برای ارتقای عملکرد مکانیکی آسفالت متخلخل و کاهش آلاینده­های موجود در رواناب سطحی از نانوذرات تیتانیوم دی‌اکسید و نانوذرات گرافن اکسید  استفاده شد. لذا، 11 نمونه در نظر گرفته شد که ابتدا آسفالت بدون نانو مواد ساخته شد سپس 4 نمونه آسفالت متخلخل حاوی نانوذرات تیتانیوم دی‌اکسید و 4 نمونه آسفالت متخلخل حاوی نانوذرات گرافن اکسید با غلظت 2 الی 8% ساخته شد. نتایج آزمایش مدول انعطاف‌پذیر نشان داد که نمونه آسفالتی حاوی نانوذرات گرافن اکسید با غلظت 6% بهترین عملکرد داشته است و به‌عنوان درصد نانومواد بهینه معرفی شد و در بخش محیط­زیستی، نمونه آسفالتی حاوی نانوذرات تیتانیوم دی‌اکسید با غلظت 8% بهترین عملکرد را داشت.

چکیده [English]

Today, with the growth of the population and the increase in water, and air pollution, the issue of water purification and the use of nanomaterials has been the focus of many researchers. Considering that environmental issues such as the reduction of pollutants in porous environments such as asphalt are important. Therefore, the aim of this research was to investigate the role of nanomaterials in improving flexibility and removing pollution in porous asphalt in urban surface runoff. For this purpose, titanium dioxide and graphene oxide nanoparticles were used to improve the mechanical performance of porous asphalt and to reduce the pollutants in the surface runoff. Hence, 11 samples were considered; first asphalt without nanomaterials was made, then 4 porous asphalt samples containing titanium dioxide nanoparticles and 4 porous asphalt samples containing graphene oxide nanoparticles with a concentration of 2-8% were made. The results of the flexible modulus test showed that the asphalt sample containing graphene oxide nanoparticles with a concentration of 6% performed best and was introduced as the optimal nano percentage, and in the environmental section, the asphalt sample containing titanium dioxide nanoparticles with a concentration of 8% was the best.
