MİKRODALGA ISITMA İLE GELİŞTİRİLEN ÇOK İNCE ASFALT KAPLAMANIN KIRILMA DİRENCİ VE KENDİ KENDİNİ İYİLEŞTİRME POTANSİYELİ

Öz

Çok ince asfalt kaplamalar, azaltılmış kalınlıkları nedeniyle kayma direncinin artırılması, gürültünün azaltılması ve tekerlek izi direncinin iyileştirilmesi gibi birbiriyle çelişen ihtiyaçların dikkatli bir şekilde dengelenmesini gerektirir. Bu dengenin sağlanması, nominal maksimum agrega boyutunun (NMAS) küçültülmesini ve daha kaba agrega derecelendirmelerinin kullanılmasını içerir. Bu tasarım karmaşıklığı, çatlamaya daha yatkın olan yarı yoğun dereceli çok ince kaplamalar için özellikle kritik öneme sahiptir. Bu bağlamda, çok ince asfalt kaplamaların mikrodalga ısıtma yoluyla iyileşme potansiyelinin araştırılması, ekonomik ve çevresel etkileri en aza indirirken kaplama ömrünü uzatmak için umut verici bir fırsat sunmaktadır. Bu çalışma, mikrodalga ısıtma altında Yarım Dairesel Eğilme (SCB) testi kullanılarak uygulanan Kırılma–İyileşme–Kırılma (FHF) döngüleri aracılığıyla iki farklı karışımın çatlama direnci ve kendi kendini iyileştirme yeteneklerini incelemekte ve karşılaştırmaktadır. İncelenen karışımlar; çok ince kaplamalar için tasarlanmış yarı yoğun agrega derecelendirmesi (BBTM8) ve %50 geri kazanılmış asfalt kaplama (RAP) içeren, bağlayıcı tabaka için kullanılan yoğun dereceli agrega karışımıdır (ACL 16+). Sonuç olarak, ACL karışımı daha yoğun derecelendirme yapısı, daha büyük NMAS değeri, daha yüksek sertliği ve daha fazla RAP içeriği sayesinde 37,1 N/mm³/² değerinde kırılma tokluğu (KIC) sergilemiştir. Buna karşılık, BBTM8 karışımının başlangıçtaki KIC değeri 18,4 N/mm³⁄² olarak ölçülmüştür. Ancak mikrodalga ısıtma sonrasında, daha yüksek hava boşluğu içeriğinin de katkısıyla BBTM8 karışımının KIC değeri önemli ölçüde artarak ACL karışımının seviyesine yaklaşmıştır. FHF döngüsü sonuçları, BBTM8 karışımının ACL karışımına kıyasla daha yüksek kırılma direnci ve daha etkin bir iyileşme performansı gösterdiğini ortaya koymuştur.

FRACTURE RESISTANCE AND SELF-HEALING POTENTIAL OF VERY THIN ASPHALT OVERLAY ENHANCED BY MICROWAVE HEATING

Abstract

Very-thin asphalt overlay mixtures require a careful balance of competing demands, such as enhancing skid resistance, reducing noise, and improving rutting resistance, due to their reduced thickness. Achieving this balance involves reducing the nominal maximum aggregate size (NMAS) and incorporating coarser aggregate gradations. This design complexity is particularly critical for semi-dense graded very-thin overlays, which are more susceptible to cracking. In this context, investigating the healing potential of very-thin asphalt overlays through microwave heating offers a promising opportunity to extend pavement life while minimizing economic and environmental impacts. This study investigates and compares the cracking resistance and self-healing capabilities of two mixtures by applying Fracture–Healing–Fracture (FHF) cycles using Semi-Circular Bending (SCB) testing under microwave heating. The mixtures examined include a semi-dense aggregate gradation (BBTM8) designed for very-thin overlays, and a dense-graded aggregate mixture (ACL 16+) intended for binder courses and containing 50% reclaimed asphalt pavement (RAP). As a result, the ACL mixture exhibited a fracture toughness (KIC) value of 37.1 N/mm³⁄², attributed to its denser gradation, larger NMAS, higher stiffness, and greater RAP content. In contrast, the initial KIC value of the BBTM8 mixture was 18.4 N/mm³⁄². However, following microwave heating, the KIC value of the BBTM8 mixture increased significantly and approached that of the ACL mixture, aided by its higher air void content. The FHF cycle results revealed that the BBTM8 mixture demonstrated higher fracture resistance and more efficient recovery performance than the ACL mixture.
