Ordonez, Carlos A (Civil & Environmental Engineering, 2007-08-23)The engineering product known as RAP is a bonded base and sub-base material produced by the process of blending crushed recycled construction and demolition waste and debris to specified gradation requirements, and by ... -
Development Of A Suction-controlled Resonant Column Apparatus With Self-contained Bender Elements
Suescun-Florez, Eduardo Alfonso (Civil & Environmental Engineering, 2010-07-19)Small-strain soil stiffness properties such as shear modulus, shear wave velocity, and material damping, are key subsoil parameters for an adequate analysis and design of unsaturated earth structures subject to static and ... -
Dynamic Properties Of Compacted Soils Using Resonant Column With Self-contained Bender Elements
Mohammad, Roshnara (Civil & Environmental Engineering, 2008-08-08)A comprehensive series of resonant column and bender elements tests were simultaneously performed in the developed RC/BE apparatus. RC/BE tests were conducted on compacted specimens of poorly graded sand (SP) and high ... -
Effect Of Stress And Suction Histories Dynamic Properties Of Statically Compacted Silty Sand
Douglas, William Allan (Civil & Environmental Engineering, 2012-07-25)This paper is devoted to the analysis of the experimental study whose intent is to find the effect of the stress/suction history on the dynamic properties of silty sand subjected to small- to mid-strains. The practical ... -
Effect Of Suction On Dynamic Properties Of Unsaturated Soils At Mid- To High-shear Strain Amplitudes
Pino Bravo, Alejandro Hernan (Civil & Environmental Engineering, 2013-10-22)This paper presents the results from an experimental study that has been designed to assess the effect of the suction and net mean stress on the dynamic properties of poorly graded sand with silt subjected to small- to ... -
Experimental Investigations On Small-strain Stiffness Properties Of Partially Saturated Soils Via Resonant Column And Bender Element Testing
