Abstract

İklimsel
farklılıkların sıkça yaşandığı bölgelerde mühendislik yapıları farklı yükler
altında olumsuz etkilemektedir. Bu etkinin iri taneli zeminlerde çeşitli atık
malzemeler katılımıyla azaltılması yönünde çalışmalar yapılmaktadır. Bu çalışma
da atık lastik parçalarıyla (AL) güçlendirilmiş iri taneli zeminin (TZ)
donma-çözülme sonucu mukavemetlerindeki değişim incelenmiştir. Deneyler
standart proktor enerjisi altında sıkıştırılması ile hazırlanan iri taneli
zemin numuneleri üzerinde yürütülmüştür. Bu iri taneli zemin örneğine

Investigation on the variation of strength of coarse grained soils reinforced with waste tires pieces as a result of freezing and thawing cycles

Abstract

In
regions where climatic differences frequently are affects especially engineering
structures under different loads. This effect is being studied to reduce the
participation of various waste materials in coarse grained soil. In this study,
the changes in strength of coarse grained soil (CG) reinforced with scrap tire
pieces (ST) was investigated under freezing- thawing conditions. Experiments
were conducted on coarse grained samples prepared by compression under standard
proctor energy. Unconfined compressive strength values of coarse grained soil
sample with



















 and

 addition of scrap tires were determined at
studied temperature (

 oC) on days 1, 7 and 28. The highest increase rate
of strength was
