The plastic limit of clays [PDF]

open access: yes, 2013
The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Design and technology concepts in providing auxiliary track roadbed stability on permafrost [PDF]

open access: yesE3S Web of Conferences
The main reason for the loss of sustaining capacity in structures on permafrost is connected with settlements that take place in thawing soils of the roadbed in its enclosed spaces in the subgrade. The technogenic impact of the linear structures produces

Resilient modulus prediction of soft low-plasticity Piedmont residual soil using dynamic cone penetrometer

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2018
Dynamic cone penetrometer (DCP) has been used for decades to estimate the shear strength and stiffness properties of the subgrade soils. There are several empirical correlations in the literature to predict the resilient modulus values at only a specific
