Özet:

 This study investigated the effects of using lime of three different origins in the mixture in specific proportions instead of fillers in hot mix asphalts. The performance changes of the mixture were investigated when three different hydrated powdered limes produced from the quarries in the Kavak district of Samsun were used as fillers to varying rates in the hot asphalt mixtures. In the study, hot mix asphalt samples were prepared by reducing the amount of filler in the mixture by 0.5, 1, 1.5, and 2, as well as lime-free samples, by adding lime of three different origins, which were supplied in the same amount. Then, the same sample group was reproduced and conditioned according to the AASHTO T 283 standard to compare and investigate the effects of water damage on the performance of the hot mix asphalt. The results of both groups of samples were compared according to Marshall stability and flow values. In the analyses made, it has been determined that the sum of CaO and MgO is greater than the 90 threshold recommended in the Highways Technical Specification HTS, and the SO3 is less than the 2 threshold recommended in the HTS are effective in increasing the pavement performance in both cases.

 Çalışmada, sıcak karışım asfaltlarda filler yerine üç farklı menşeili kirecin belirli oranlarda karışımda kullanımının etkileri araştırılmıştır. Samsun ili Kavak ilçesinde bulunan ocaklardan üretilen üç farklı sönmüş toz kirecin, sıcak asfalt karışımlarında farklı oranlarda filler olarak kullanılması durumunda karışımın performans değişimleri incelenmiştir. Çalışmada sıcak karışım asfalt numuneleri, kireçsiz numunelerin yanında karışım içerisindeki filler miktarı 0.5, 1, 1.5, 2 oranlarında azaltılarak yerine aynı miktarda temin edilen üç farklı menşeili kireç ilave edilerek hazırlanmıştır. Ardından, su hasarının sıcak karışım asfaltın performansına etkilerini karşılaştırmak ve araştırmak için aynı numune grubu tekrar üretilerek AASHTO T 283 standardına göre koşullandırılmıştır. Marshall stabilite ve akma değerlerine göre her iki grup numunenin sonuçları karşılaştırılmıştır. Yapılan analizlerde her iki durumda da CaO ve MgO toplamının Karayolları Teknik Şartnamesinde KTŞ önerilen 90 eşiğinden büyük olmasının ve SO3ün KTŞde önerilen 2 eşiğinden küçük olmasının üstyapı performansını arttırır şekilde etkili olduğu tespit edilmiştir.
