Abstract
Asfalt üretiminde uygulamaya konulan bilimsel gelişmelerden biri de ılık karışım asfalt
teknolojisidir. Ilık karışım asfalt teknolojisi ile daha düşük sıcaklıklarda asfalt üretimi mümkün
olmaktadır. Bu çalışmada, Pawma-1 (%0,35) ve Low Energy and Low Carbon-Dioxide Asphalt Pavement
(Leadcap) (%1,5) ılık karışım asfalt katkı maddeleri ile Stiren-Butadien-Stiren (SBS) (%2) katkı maddesi
karışım numunelerinde denenmiştir. Bununla beraber, sönmüş kirecin ılık karışım asfaltlarda filler olarak
kullanımının etkileri de incelenmiştir. Çalışmada TÜPRAŞ rafinerisinden temin edilen bitüm (B50/70) ve
agrega olarak Elazığ Hankendi bölgesinden temin edilen kalker türü kırmataş malzeme kullanılmıştır.
Modifiye bağlayıcılar hazırlandıktan sonra Marshall yöntemine göre optimum bitüm oranları belirlenerek
karışım numuneleri hazırlanmıştır. Karışım numunelerinin yarısında filler yerine %2 oranında sönmüş
kireç kullanılmıştır. Hazırlanan numuneler üzerinde Marshall stabilite ve akma deneyi (ASTM D-1559)
uygulanmıştır. Leadcap, Pawma-1 ve SBS katkıları ile hazırlanan karışımlarda stabilite artmıştır. Sönmüş
kirecin, ılık karışım asfaltların stabilitelerini arttırdığı görülmüştür. Sönmüş kireç katkılı SBS modifiyeli
karışımların en olumlu sonuçları verdikleri tespit edilmiştir.

Abstract
One of the scientific advances put into practice in asphalt production is warm mix asphalt
technology. By warm mix asphalt technology, it is possible to produce asphalt at lower temperatures. In
this study, Pawma-1 (%0.35) and Low Energy and Low Carbon-Dioxide Asphalt Pavement (Leadcap)
(%1.5) warm mix asphalt admixtures and Styrene-Butadiene-Styrene (SBS) (%2) admixture were tested
in mixture samples. The effects of the use hydrated lime in warm mix asphalt as filler, have also been
examined. Bitumen (B50/70) obtained from TÜPRAŞ refinery was used in the study. Limestone type
crushed stone material obtained from Elazığ Hankendi region was used as aggrates. After preparing the
modifier binders, mixture samples were prepared by determining the optimum bitumen contents
according to the Marshall method. 2% hydrated lime was used instead of filler in half of the mixture
samples. Marshall stability and yield test (ASTM D-1559) were applied on the prepared samples.
Stability increased with Leadcap, Pawma-1 and SBS additives. It has been shown that the hydrated lime
increases the stability values of warm mix asphalts. It has been determined that SBS modified mixtures
with hydrated lime gave the most positive results.
