Abstract

Abstract

Rubber particles from crushed waste tires mixed with soil can improve the engineering properties of soil. In order to improve the utilization rate of waste tires and solve the engineering problems of expansive soils， this study took the expansive soil in the Jiutai area of Jilin Province as the research object. Freezing and swelling tests of modified expansive soil under different factors （water content， particle size， and mix proportion） were carried out in a closed system to investigate the effects of freezing and swelling， temperature change， and moisture migration on modified expansive soil. This paper analyzed the coupling effects of rubber particle dosage， rubber particle size， and water content. The test results showed that the deformation of expanded soil was closely related to initial water content， rubber particle dosage， and rubber particle size： specimens with low water content and small rubber particle size exhibited frost contraction， while those with high water content and large rubber particle size showed frost expansion. An appropriate amount of rubber particle dosage could suppress both the frost expansion and frost contraction of the soil samples. The distribution of the final water content of the expansive soil along the depth direction was characterized as follows： water content in the frozen area increased， water accumulated in the freezing front， and water content in the unfrozen area decreased.
- expansive soil,
- rubber granules,
- frost expansion,
- freezing fronts
