Stabilization of highway embankment using stabilized cohesive frictional soil with shredded scrap tire / Anas Ibrahim … [et al.]

Limitation of exceptional construction sites, particularly due to fast
growing of human population and economic development is common
nowadays in Malaysia. Utilization of waste materials, which are
lightweight, was one of the possible solutions that can be used to
solve bearing capacity and settlement problems of embankments on
soft compressible soil. It has been found that the utilization of tire
shreds in highway construction offers economic and environmental
benefits. Research focused on the determination of physical and
engineering properties of stabilized cohesive frictional soils using
shredded scrap tires. Laboratory tests according to British Standard
1377 were performed on untreated cohesive frictional soil, 100%
shredded tire and mixtures of the soil and shredded tire by ratios of
90%-10%, 70%-30%, 50%-50%, 30%-70% and 10%-90%. Results
show that admixtures of soil and shredded tires by ratio of 70%-
30% give highest improvement in term of shear strength parameters
with 23% improvement of internal friction angle compared to the
untreated cohesive frictional soil with 31° of internal friction angle.
Mixtures of 50%-50% produced the best lightweight mixtures with
internal friction angle value was 34° and the maximum dry density
was 44% lower compared to the untreated soils respectively.
