Investigation of Water and Soil Migration and Mud Pumping of Subgrades under Traffic Load
Atmosphere, 2023 Atmospheric precipitation leads to the increase of moisture in the subgrade. The moisture and soil migration in subgrade is a key scientific problem in evaluating the service performance of the subgrade and resolving or preventing mud pumping.

The Cooperative Control of Subgrade Stiffness on Symmetrical Bridge–Subgrade Transition Section
Symmetry, 2022 In the field of civil engineering and architecture, the concept of symmetry has been widely accepted. The bridge can be treated as a typical symmetrical structure of civil engineering buildings. Among them, the Subgrade can be identified as an important part to bear the vehicle loads.

Subgrade Stabilization Alternatives [PDF]
, 2020 Recent research has shown that the subgrade soil type and its engineering properties govern the performance of the pavement, especially for clayey soils. However, current application of the Pavement_ME in Indiana does not fully account for the changes of type of soil and stiffness that may arise with treatment.
