Investigation on the variation of strength of coarse grained soils reinforced with waste tires pieces as a result of freezing and thawing cycles
Öz
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
in CG+
ST (
)
mixture,
in CG+
ST (
)
mixture and
in CG+
ST (
)
mixture. The freeze-thaw test was applied on this mixture. The results showed
that while the strength rate of CG+
ST (
)
and CG+
ST (
)
mixtures decreased to
and
respectively; the strength of CG+
ST (
)
mixture increased to
