Abstract:
Deep soft soil subgrades are susceptible to environmental impacts from neighboring engineering activities, such as excavation and foundation treatment, which can lead to significant deformation and potential disasters. In response to the environmental impact of neighboring engineering construction on deep soft soil roadbeds, this article analyzes the effects and mechanisms of vacuum combined preloading and foundation pit engineering on the deformation of such subgrades, respectively, as well as the resulting pavement diseases.

This research addresses the characteristics of soft soil subgrades treated by soilbags filled with excavated clayey soil. We evaluated of the strength and deformation modulus of soilbags containing excavated soil using unconfined compression tests. In addition, the drainage consolidation characteristics of soilbag-treated subgrades were investigated via model consolidation tests. Furthermore, a practical application included the construction of a 100 m-long rural road subgrade with these soilbags.

Abstract:
In the construction of high-speed railways in our country, various complex terrains and geologies are often encountered. Therefore, the treatment of special subgrades, especially the reinforcement of soft soil subgrades, becomes extremely important. Currently, there are many methods for reinforcing weak and soft soil foundations, and during construction, appropriate and economical treatment methods should be selected based on the actual site conditions. This article intends to use the reinforcement treatment of the subgrade in the section from DK30+000 to +347.62 of the Ningbo-Hangzhou Passeng

Abstract:
The effectiveness of flexible pavement is affected by the subgrade quality. The subgrade refers to a compacted layer of soil that provides sideways support to the pavement. When constructed on a weak subgrade, it negatively impacts the pavement's performance, leading to a shorter lifespan. Traditionally, the common method to stabilize a soft subgrade involves removing the weak soil and replacing it with stronger soil. However, due to the high expenses associated with soil replacement, highway agencies are exploring alternative approaches to constructing highways on soft subgrades. Soil stabili

The subgrade of road construction also determines the strength and resistance to loads on it. The subgrade in the field very varies from soft clay to hard soil. The subgrade of soft clay requires soil improvement to increase bearing capacity. This study aims to determine the increase in bearing capacity and modulus of subgrade reaction in stabilized soil with the bamboo grid. The research was conducted through a physical model using a test box. Soft clay is compacted and the above it is replaced with stabilized soil with and without the bamboo grid.

The results show that settlement develops gradually with the increasing period of soil consolidation.

The test setup featured a fully instrumented unpaved road model comprising a 0.2-m-thick crushed rock base supported by a 0.8-m-thick soft clay subgrade. The triaxial geogrid was positioned between the base and subgrade layers. Plate bearing tests were performed following ASTM standards. The thickness of the triaxial geogrid-reinforced base layer played a critical role in determining the unpaved road model’s ultimate bearing capacity and failure modes. Results showed that th

Abstract:
Railway tracks experience elevated rail deflections when the supporting soil is soft and/or the train speed is greater than approximately 50% of the wave propagation velocity in the track-soil system (i.e. the critical velocity). Such vibrations are undesirable, so soil replacement or soil improvement of the natural soil (or alternatively mini-piles or lime-cement treatment) is often used to increase track-ground stiffness prior to line construction. Although areas of existing soft subgrade might be easily identified on a potential new rail route, it is challenging to determine the type and de

Many pavement subgrades in Virginia consist of wet, highly plastic clay or other troublesome soils. Such soils can be treated with traditional lime and cement stabilization methods. Alternatives, including lignosulfonates and polymers, are available, but their performance record is mixed and solid engineering data is lacking, which prevents reliable design. The goal of this research was to screen a suite of traditional and non-traditional stabilizers against three Virginia soils that have caused problems during construction or resulted in poor performance in service.

Trackbeds are typically composed of all granular materials comprised of ballast and subballast over compacted subgrade. Most poor performances of railroads can be attributed to poor and unstable subgrade conditions. Below the surface, the instability of the subgrade material can propagate through the granular zone leading to excessive settlements and deformations of the railway. Conventional subgrade restoration in the trackbed system requires the removal of the granular materials and over-excavation of soft unstable subgrade materials, moisture adjustment, re-compaction, and sometimes chemica
