Millions of PET bottle wastes occur in the world. These wastes are used as additives in different ways in solid form in many areas However, using PET bottle waste in solid form limits their usability in some areas (geotechnics, building materials). In this study, the effect of liquefied PET bottle waste(LPBW) on some physical and mechanical properties of fine-grained soil was investigated. For this purpose, Atterberg Limits (wL, wP) and unconfined compressive strength tests were carried out with the samples prepared by adding different ratios (5%, 10%, 15% and 20%) to the mixing liquid of the fine-grained soil, which was turned into viscous liquid PET bottle wastes. From the results of the experiments carried out in the laboratory, it has been shown that adding liquefied PET bottle waste material to the mixing water at a rate of up to 5% increases the unconfined compressive strength. In addition, it was determined that the workability of fine grained soils increased with the increase of liquefied PET bottle waste added to the mixing water.

Dünya’da çevresel sorunlara yol açan milyonlarca adet PET þiþe atýðý ortaya çýkmaktadýr. PET þiþe atýðý katý formda farklý þekillerde katký malzemesi olarak deðerlendirilmektedir. Ancak PET þiþe atýklarýný katý halde deðerlendirmek bazý alanlarda(geoteknik, yapý malzemesi) kullanýlabilirliklerini sýnýrlý kýlmaktadýr. Bu nedenle çalýþmada sývýlaþtýrýlmýþ PET þiþe atýklarýnýn(SPÞA), ince taneli zeminin bazý fiziksel ve mekanik özellikleri üzerindeki etkisi araþtýrýlmýþtýr. Viskoz sývý haline getirilen PET þiþe atýklarý ince taneli zeminin karýþým sývýsýna farklý oranlarda (%5, %10, %15 ve %20) ilave edilerek hazýrlanan numuneler ile Atterberg Limitleri (wL, wP) ve serbest basýnç mukavemeti deneyleri yapýlmýþtýr. Laboratuvarda yapýlan deney sonuçlarýndan sývýlaþtýrýlmýþ PET þiþe atýk malzemesinin %5 oranýna kadar karýþým suyuna ilave edilmesi serbest basýnç mukavemetini artýrdýðýný göstermiþtir. Ayrýca karýþým suyuna ilave edilen sývýlaþtýrýlmýþ PET þiþe atýk oranýnýn artmasý ile ince taneli zeminlerin iþlenebilirliðinin arttýðý belirlenmiþtir.
