801042 ~~'sL~S OF WATER ADSORPi~ON ON KAOLIN CLAY DURING SHEAR Gle~n, G R Transp Res Rec I~75, 1978, P20-23 Reports stress-controlled a~d strain-cont~olled direct shear tests on lab desiccated specimens in which the standard apparatus was modified to I ~ = ~ i t progressive adscrption of water. Results are analysed qualitatively in relation to ~he Coulomb equation add the Irinciple of effective stress.
