Abstract Waste material such as used tires is increasing every year, which poses environmental problems. However, such material has been used in several geotechnical applications as alternative lightweight backfill in highway embankments and/or behind retaining walls, providing environmental, economic and technical benefits. These applications require knowledge of engineering properties of soil-tire rubber mixtures. The present study aims to show the possibility of tire rubber usage in sand by evaluating the shear strength and deformability of sand mixed with granulated rubber, in weight percentages between 0 and 50%. The tire rubber content was found to influence the stress-strain and deformation behavior of the mixtures. The shear strength of sand mixed with 10% or 20% tire rubber was higher than that measured for sand only. However, the trend for TRC = 30–50% was different. Samples with a rubber content of 30-50% exhibited a rapid decrease in the stress ratio compared with that of sand. The major principal strain at maximum stress ratio was found to increase with increasing tire rubber content. However, it was observed that the lateral strains (minor and intermediate principal strains) of samples reduced significantly with the addition of tire rubber to the sand.

Cement Soil

Unconfined compressive strength tests of soil with different cement dosage of stabilization have been conducted to determine the optimum cement stabilizing dosage. And, the shear strength and deformation of the geocell reinforced cement soil have been investigated through a serial of direct shear tests and plate-loading tests. The results show that there is a significant improvement on shear strength and modulus of the soil by reinforcement. Moreover, FEM has been used to simulate and analyze the performance of abutment with geocell reinforced cement soil backfill. And the comparison of the computing results to field testing results has been carried out. The research results indicate that: the abutment with wedge-shape geocell reinforced cement soil backfill has remarkable effect on decreasing the differential settlement on bridge-embankment transition section. The gradient of settlement along the longitudinal direction of bridge-embankment gets much more smooth-going and less.

The Relationship

This paper studies relationship between soil-cement parameters and unconfined compressive strength. The research in tensile strength and deformation modulus of soil-cement is an important basis for soil-cement failure mechanism and intensity theory. They also impact cracks, deformation and durability of cement-soil structure. Shear strength and deformation of soil-cement is important to the destruction analysis and finite element calculations. Therefore it needs to study on tensile strength, shear strength and deformation modulus of soil-cement. Based on previous experiments, the relationship of tensile strength, shear strength, deformation modulus and unconfined compressive strength of soil-cement are quantitatively studied.
