Abstract

Asphalt concrete has an extensive application field in road construction. Studies aiming to increase the performance of asphalt concrete have gained importance since the cost of road construction is quite high and resources are limited. On the other hand, researchers have inclined to use various wastes in asphalt concrete since the wastes from houses and industrial production has increased all over the world and the storage areas for these wastes are inadequate. The use of various wastes in asphalt concrete has become important since obtaining aggregate in good quality becomes difficult and bitumen cost has risen. In recent years, studies have increased progressively in relation to recycling of wastes and to increasing asphalt concrete performance with superstructure layers which are less in thickness. In this study, the experimental results have been summarized in relation to the use of modified bitumen in asphalt concrete, which are CR-10 and CR-15 and contain specially-treated tires. The elastic recovery rate of the modified bitumen from waste is 10 times more than normal bitumen. The penetration and softening point values of the modified bitumen s CR-10 and CR-15 are higher than that of others. In addition, these products have a very low heat loss; therefore it can be possible to make castings in cold weather conditions. The behavior of asphalt concretes under repeated loads was investigated and asphalt concretes produced with CR-10 and CR-15 modified bitumen s have proven to be longer lasting. In this way, using waste tires as a modifier in the bitumen not only improve the performance characteristics of the asphalt concrete but also help to

Özet

Asfalt betonunun yol inşaatlarında kullanımı oldukça yaygındır. Yol inşşatı maliyetlerinin yüksek olması ve kaynakların kısıtlı olması nedeniyle, asphalt betonunun performansını artırıcı çalışmalar önem kazanmıştır. Diğer taraftan, tüm dünyada evsel ve endüstriyel atıkların artması, bu atıkların stok alanlarının sınırlı olması nedeniyle araştırmacılar atık malzemelerin asphalt betonunda kullanımı eğilimindedirler. İyi kalitede agrega elde etmenin zorluğu ve bitüm malzemesinin maliyetli olması atıkların asphalt betonunda kullanımının önemini artırmıştır. Son yıllarda, yol inşaatlarında asphalt betonunun performansını artırmaya yönelik çalışmalar hız kazanmıştır. Bu çalışmada, CR-10 and CR-15 isimli, işlenmiş atık lastik içeren modifiye bitümün asphalt betonunda kullanımına yönelik deneysel çalışmalar özetlenmiştir. Bu atıklar ile modifiye edilen bitüm, normal bitume nazaran 10 katı elastik geri dönüş özelliği kazanmaktadır. Penetrasyon ve yumuşama noktası değerleri CR-10 and CR-15 modifiye bitümlerinde daha yüksek çıkmaktadır. Ayrıca bu ürünlerede ısı kaybı çok düşük olduğundan soğuk hava şartlarında döküm yapabilme olanağı sağlanmaktadır. Asphalt betonunun tekrarlı yükler altındaki davranışı incelenmiş ve CR-10 and CR-15 modifiye bitümleri ile üretilen asfalt betonlarının daha uzun ömürlü olduğu ispatlanmıştır. Bu şekilde hem atık lastik kullanılarak asphalt betonunun performans özellikleri artırılabilir, hemde çevresel kirlenmenin önlenmesine katkıda bulunulabilir.
