Geogrids provide reinforcement for aggregate materials through interlocking between granular particles and geogrid apertures. The reinforcement or stabilization effect of a geogrid can be quite different when used with similar aggregate types but having different particle size distributions. This paper describes recent research efforts at the University of Illinois focused on triaxial compressi...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

Dynamic behavior of soil are evaluated relative to a number of factors including: strain level, density, number of cycles, material type, fine content, geosynthetic inclusion, saturation, and effective stress .This paper investigate the dynamic behavior of saturated reinforced sand under cyclic stress condition. The cyclic triaxial tests are conducted on remolded specimens under various CSR whi...

This study presented the overview on behavior of bentonite-sand mixture used in high level radioactive waste disposal. Both unconfined compression test and triaxial were conducted out that unsaturated-saturated samples applied temperature effect below 100 degrees Celsius. Unconfined compressive strength was determined with various temperatures different relative humidity for unsaturated specime...

Artificial cemented sand test samples were prepared by using ordinary Portland cement (OPC) as the cementing agent. Through uniaxial compression tests and consolidated drained triaxial compression tests, the stress-strain curves of the artificial cemented sand with different cementing agent contents (0.01, 0.03, 0.05 and 0.08) under various confining pressures (0.00 MPa, 0.25 MPa, 0.50 MPa and ...

The paper presents an improvement of the microplane model for concrete-a con~titutive model in which the nonlinear triaxial behavior is characterized by relations between ~e stress and stram c<?m~onents on a microplane of any orientation under the constraint that the strains on the nucroplane are the .proJection~ of the macroscopic strain tensor. The improvement is achieved by a ~ew conce~t: th...
