Abstract

Polymers are popular materials as an additive to improve the performance of hot mix asphalt (HMA). To this aim, acrylic latex was chosen to improve the performance of asphalt mixture. In this study, it was investigated that the performance of hot mix asphalt with acrylic latex additive in three percentages (1%, 2% and 3%). Design bitumen contents were determined for all acrylic latex additive. Indirect Tensile Strength and moisture susceptibility of acrylic latex added HMA was conducted using test procedure of AASHTO T283. According to the results, design bitumen contents were increased by acrylic latex. Although the bitumen content was increased, both the indirect tensile (IDT) strength and the moisture resistance were improved by acrylic latex. Best performance was obtained by 3% acrylic latex additive. It is suggested that the percentage of acrylic latex would be increased for further researches.

Akrilik Lateksin Bitümlü Sıcak Karışımların Nem Hassasiyeti Üzerindeki Etkisinin Araştırılması

Abstract

Polimerler Bitümlü Sıcak Karışımların (BSK) performansını artırmak amacıyla kullanılan popüler katkı malzemeleridir. Bu çalışmada, asfalt karışımların performansını artırmak amacıyla akrilik lateks seçilmiştir. Akrilik lateks karışıma üç farklı oranda (%1, %2 ve %3) karıştırılarak bitümlü sıcak karışımların performansı incelenmiştir. Dizayn bitüm içerikleri her bir oran için ayrı ayrı belirlenmiştir. Akrilik lateks ile karıştırılmış BSK için İndirekt çekme dayanımı ve nem hassasiyeti AASHTO T283 test prosedürü dikkate alınarak belirlenmiştir. Elde edilen sonuçlara göre, dizayn bitüm içeriği artırılmıştır. Bitüm içeriği artmasına rağmen, hem indirekt çekme (IDT) dayanımı hem de neme karşı dayanımda iyileştirme elde edilmiştir. En iyi performansı gösteren akrilik lateks katkı oranı %3 olarak belirlenmiştir. Sonraki çalışmalar için akrilik lateks oranının artırılması önerilmektedir.
