| چکیده | ||
| روسازیهای ساخته شده توسط مخلوط آسفالتی داغ با قرار گرفتن در برابر رطوبت و نزولات جوی دچار خرابی و مشکلات جدی میگردند. به منظور بررسی پتانسیل خرابی رطوبتی مخلوطهای آسفالتی، آزمایشهای مختلفی ارائه شده که روی مخلوط متراکم یا سست انجام میگیرند. معمولاً، آزمایشهای انجام شده روی مخلوط متراکم، مانند آزمایش کشش غیر مستقیم ITS، نیاز به هزینه و وقت بیشتری نسبت به آزمایشهای انجام گرفته روی مخلوط سست، مانند آزمایش آب جوشان، دارند که یکی از دلایل آن، وابستگی نتایج این آزمایشها به قضاوت انسانی است. در این مقاله، سعی شده با ارائه یک شاخص جدید عریانشدگی، نتایج کیفی و مبتنی بر قضاوت انسانی حاصل از آزمایش آب جوشان به نتایج کمی تبدیل شوند. به همین منظور، با استفاده از روش قطعهبندی تصویر به صورت k-means، نواحی عریان شده تعیین و شاخصی مبتنی بر نتایج حاصل از این روش ارائه شد. به منظور ارزیابی دقت نتایج استخراج شده توسط این شاخص، مدل آماری که ارتباط بین این شاخص و نتایج حاصل از آزمایش ITS را بیان میکند برازش داده شد. با توجه به معنیداری ضرایب مدل آماری در سطح اطمینان 95% و همچنین بالا بودن مقدار R2 (91/0) میتوان نتیجه گرفت که این شاخص برای ارزیابی حساسیت رطوبتی مخلوطهای آسفالتی مناسب میباشد. علاوه بر این، اثر خرده تراشه آسفالتی و ماده ضد عریانشدگی بر حساسیت رطوبتی نیز مورد سنجش قرار گرفت. نتایج نشان داد که با افزایش خرده تراشه آسفالتی و مقدار ماده ضد عریانشدگی، عملکرد مخلوط آسفالتی در مقابل حساسیت رطوبتی بهبود مییابد. به طوری که با افزودن خرده تراشه آسفالتی و مادهی ضد عریانشدگی به ترتیب به میزان 60 و 5/1 درصد، شاخص TSR افزایش پیدا کرده و از 71% به 95% رسید. | ||

| چکیده [English] | ||
| Hot Mix Asphalt (HMA) concrete deterioration due to atmospheric moisture is one of the common problems with flexible pavements. Different tests are used on loose or compacted specimens to evaluate HMA moisture susceptibility. Tests on compacted specimens, such as Indirect Tensile Strength (ITS), are commonly slower and more expensive in comparison to loose mixture tests such as boiling test; but their results are commonly subjective. This paper aims at developing a new stripping index to quantify subjective results of boiling test. Therefore, k-mean classification method was used to identify stripped areas in mixture and a stripping index was developed based on the results. In order to evaluate the accuracy of results of this index, a statistical model was used to find the relationship between the results of this index and the results of ITS. Considering that the model was significant at 95% confidence level and the high value of R2 (0.91), it was concluded that the index is a proper tool for evaluating asphalt concrete moisture susceptibility. In addition, the effects of using Reclaimed Asphalt Pavement (RAP) material and a liquid anti-stripping agent on moisture susceptibility was evaluated. Results showed that application of RAP and anti-stripping agent can significantly decrease moisture susceptibility, such that increasing RAP by 60% and anti-stripping material by 1.5%, the Tensile Strength Ratio (TSR) increased from 71% to 95%. | ||
