Examination of the 4 Methods of Soil Stabilization – 4 Critical Factors…
In our previous article, we explored the two broad methods of soil stabilization: direct soil modification and modification through admixture. Today, we will examine 4 Methods of Soil Stabilization, their benefits and drawbacks, and explain why Global Road Technology’s polymer-based admixture program stands out as the superior option for most applications. Here are 4 Methods of Soil Stabilization commonly employed around the globe:
- Cement Stabilization – This is one of the more common methods of soil stabilization due to the relatively low cost and wide availability of cement. Soil is basically combined and mixed with cement to add strength and durability. The end result is fairly durable and resistant to weather, making it a great choice for sandy soil environments. However, the process is relatively labour intensive, and not healthy for the environment. Additionally, while the resulting soil-cement admixture has high durability, it is still susceptible to cracking.
- Lime Stabilization – Lime stabilization is another of the popular methods of soil stabilization. This procedure is not nearly as cost-effective as cement, and it can be more expensive due to the cost of the burnt limestone required for the process. It is also bad for the environment; burning lime in kilns generates toxic runoff that can damage groundwater supply. However, it does increase the strength and stability of the soil, particularly in dry (but not sandy) environments where the material can be compacted – the total compressive strength can be increased by up to 60x in some situations.
- Chemical Stabilization – Chemical methods of soil stabilization are a wider group, as there are many different applications. The major advantage of this approach is that there is likely a chemical soil stabilization solution designed for any specific environment you may require, so performance is likely to be high. Most of the chemicals used in these processes are dangerous for the environment though, and they can be quite expensive as well.
- Polymer Stabilization – Polymer based methods of soil stabilization are the most modern and offer a number of advantages over more traditional procedures. They involve combining the soil with non-reactive, environmentally neutral polymer based filler material. One of the biggest advantages of polymer-based methods of soil stabilization such as those employed by GRT is that they do not negatively impact the environment whilst creating a waterproof, semi-flexible pavement. They also offer advantages in terms of strength and are typically one of the more affordable options as well.
Conclusion
As you can see, GRT and their polymer-based methods of soil stabilization offer a number of advantages over the other approaches. They are more cost-effective, less susceptible to damage, lasts longer, easier to maintain, and better for the environment. In almost every single metric of import, Global Road Technology products and methods represent a step forward in terms of infrastructure construction methods and technology.
The Global Road Technology Innovative range of products also enhances the properties of the host material by a combination of:
- Reducing the Plasticity Index (PI)
- Reduces Water Sensitivity
- Reduces Shrinkage
- Increases Water Impermeability
- Increases Strength (both compressive and tensile)
- Increases Load Bearing Capacity
- Increases Durability
When you factor in other benefits they bring to the table in terms of infrastructure construction, use, and maintenance, such as the GRT Road Safety Initiative, and the GRT RMS Program, it is little surprise that Global Road Technology and their innovative methods of soil stabilization and infrastructure construction have been taking the construction world by storm. From Australia to India, to South Africa, and all across the globe – GRT is changing the way roads get built.
