| Summary: | The objective of the research is to gather information on the properties of shredded
tyre in different percentage of addition with sand. A comparison will also be made to
find mixture that obtained Waste tyre disposal is a problem faced by every country in
the world today. In America alone, approximately 280 million tires are discarded
each year by American motorists. In America steps had been taken to counter this
problem where at least 15 states have utilized scrap tire shreds or chips mix with soil
as a lightweight fill material for the construction of embankments or backfills. The
most obvious advantage is that of reduced unit weight, which is especially beneficial
in situations where an embankment is to be constructed over an area with low
bearing support. Tyre shred can be a very economical alternative to imported earth
borrow.In Malaysia however, no effort had been done yet to counter this problem.
This is may due to lack of confidence in utilizing waste tyre. This can be countered
by conducting research to gather knowledge on this material.
the most valuable engineering properties. Past research had show that the mixture
possessed properties suitable for engineering use such as well gradation in particles,
low unit weight and acceptable internal angle of friction.
A property of this mixture is determined by conducting a sieve test, proctor test and
shear box test. The mixture is determined by percentage of shredded tyre added to
certain weight of sand river. The percentage of shredded tire is 10%, 30%, 50%, 70%
and 90% of dry weight of river sand. 100% Sand River and 100% shredded tire act as
reference.
The result of the testing indicated that 30% addition of tyre produce the best
properties for engineering used. In this mixture, it is classified as a well graded
particles, a maximum dry density of 1.5 Mg/m3 with optimum moisture content of
12.9%. The 30% mixture of tyre also possesses an angle of internal friction of 300
with cohesion value of 7.88Kpa. The results also indicate tyre can be stated as a
cohesion agent to the mixture while sand as a factor to the increase in internal angle
of friction. The availability of tyre in mixture also resulted a lighter mass suitable for
embankment. |
