QUALITATIVE RELATIONSHIPS OF WATER MIGRATION IN HIGHWAY EMBANKMENT CLAY SOILS BY THE RESULTS OF LABORATORY AND FIELD RESEARCH
Abstract
As a result of quantitative data analysis by laboratory and field experiments quantitative
patterns of water migration in compacted silty loam embankment, including the stabilized (or
final) clay soil moisture values, depending on their type (number plasticity), soil skeleton
density, embankment height and time «rest» of the subgrade before it’s operation are
established. The soil moisture changes graphs at what the loam was compacted from soil
skeleton density and stabilized soil moisture of already compacted loam after the subgrade
«rest» from soil skeleton density are plotting in the article. The empirical dependence of
compacted silty loams stabilized moisture for their multilayer consolidation is obtained.
Empirical dependence parameter corresponds to maximum molecular moisture capacity at
what it is advisable to do the subgrade clay soils multilayer consolidation for the ensuring their
long-term strength.
Keywords: water migration, compacted loam, soil skeleton density, plasticity number,
stabilized moisture, two-factor analysis, empirical dependence.
