Soil Instability Troubleshooting Tips for Paving Projects

When you begin a new paving project, you never know what the ground underneath has in store for you. Often times, people will come across highly unsteady soil conditions, bringing their work to a sudden halt. After all, you cannot properly pave over soil that is in poor or unstable condition. For paving, you want optimal ground reinforcement for best results. If your soil conditions are holding you back from making paving renovations or improvements, continue reading to learn some helpful trouble-shooting tips for treating and preventing soil instability.

What Causes Unstable Soil?

There are three common causes for soil instability: poor compaction, organics, and general composition. Let’s start with the presence of organics. When plants, dead insects, and living organisms within topsoil decay and break down, the soil becomes increasingly unstable. As for compaction, soil compaction is a top requirement for proper ground reinforcement.

However, soil can lose compaction as a result of a long list of potential facts, such as flooding, improper construction, poor water drainage, and more. When it comes to general composition, it plays a large role in how well soil can hold up against a topping of pavement. You see, soil maintains certain pH levels, and requires a healthy balance of air, water, and minerals. Without a proper balance, the soil will become exponentially unstable.

How to Stabilize Soil

To prevent soil instability, it is important to have your property inspected by professional Indianapolis paving contractors who understand the proper methods and techniques of laying pavement in unstable conditions. They can assess the current condition of your soil stability, and make modifications to improve it if you choose to move forward with work.

To treat soil instability, there are a few methods you can try:

➲ Use drainage tiles to rid excess water and moisture from your soil.
➲ Turn and till your soil routinely to promote drying.
➲ Excavate into the sub-grade and replace poor soil with good soil.
➲ Bridge the unstable soils with a suitable base material.
➲ Install a geo-grid (reinforcing grid).
➲ Change the chemical composition through chemical stabilization.
➲ Implement foamed asphalt injections.

The Benefits of Asphalt Subgrade Stabilization

When the existing base or subgrade material is altered for the purpose of improving its strength and durability prior to asphalt pavement installation, the process is called base stabilization. This is closely related to a similar process in the paving industry called soil stabilization, in which soil or soil components are enhanced so that paving material can be installed on top. So why is base stabilization necessary in the asphalt paving process? Continue reading to find out.

The Importance of Subgrade Stabilization

Subgrade stabilization allows for proper asphalt paving. Not only does it decrease the plasticity of a base, it also lowers the water content, all of which increases its strength. The process of subgrade stabilization is complex, and several factors influence the methods and level of difficulty. Because of this, it is necessary to make test out a few different mixtures the find the proper combination suitable for the particular paving application.

Influential Factors include but are not limited to:

⚎ The condition of the existing and underlying soil;
⚎ The degree of base plasticity;
⚎ The depth of the local water table;
⚎ The current freeze/thaw conditions.

Subgrade Stabilization Advantages

Base stabilization provides many benefits, including the ones mentioned earlier. Aside from strength, water content, and plasticity, stabilizing a subgrade is highly cost-effective solution for soil instability problems. This is especially true for swampy or sandy areas and marshlands. Additionally, subgrade stabilization is environmentally-friendly since the chemicals used to treat the soil reduce greenhouse gas emissions. Also, less energy is used since the materials for soil stabilization are on the low end of the energy-utilization spectrum.
