The Critical Link Between Soil Stability and Paving

When it comes to paving, there is always the possibility of the unexpected, and often times, unstable ground soil can be one of those unexpected obstacles pavers run into. Continue reading to learn more about soil instability, how it affects the paving process, and of course, how to fix it.

Top Causes of Soil Instability

The most common causes of unstable soil involve three issues: 1) composition, 2) compaction, and 3) organic matter. The presence of all three of these components, and the degree of their severity, have a direct influence on soil stability, but will vary from property to property.

When the ground is not evenly elevated, soil can be poured into missing gaps to create an even surface. But when soil is not poured and compacted in thin layers, it lacks proper support capacity. Soil must be compacted and uniform to provide a stable foundation for paving.

Soil Composition Affects Stability

When the ground soil contains high traces of organic matter, it can also be very unstable for paving projects. Topsoil, plant matter, and decomposing insects can become a stability problem when mixed with precipitation like rain or snow.

The most common cause of soil instability is composition. Strong soil retains a healthy balance of natural minerals, matter, water, and air. With the right balance, soil is stable enough for paving; but if soil lacks a balanced composition, it can be extremely problematic for paving projects.

How to Solve a Soil Instability Problem Before Laying Pavement

There are several soil stabilization methods paving contractors are likely to use for properties whose ground soil does not meet certain stability criteria. For example, pavers will use drainage tiles to remove excess moisture from soil. More methods of soil stabilization include:

Installing Reinforcement Grids
☑ Chemical Stabilization
☑ Tilling and Turning Over Soil
☑ Dirt Sub-Grade Excavation
☑ Soil Replacement
☑ Soil Bridging
☑ Foamed Asphalt Injections
☑ Installing Soil Separation Fabric

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.

Why Can Soil Become Unstable Below Old Asphalt?

Often times, paving companies or contractors will begin a paving project, only to find that the soil beneath the old pavement is too soft and not stable enough to take on new material. There are a few common causes for soil instability, all of which can interrupt a paving project. But fortunately, unstable soil can be resolved. It just takes a few extra steps. Continue reading to learn what causes soil instability, and how to fix it for purposes of paving.

Causes of Soil Instability

There are three main causes of soil instability: 1) organic presence, 2) lack of compaction, and 3) poor composition. Look below for a brief explanation of each issue.

Organic Presence – The excessive presence of organic matter, especially decomposing organics, can cause soil to soften, making it unstable. This includes insects, leaves, plant matter, and water.

Poor Compaction – When soil lacks compaction, it is weak and does not retain the ability to properly bear weight. Lack of compaction means soil is soft and unable to stabilize for the purpose of bearing weight, such as paving material.

Poor Composition – The make-up of soil has a major influence on its level of stability. When improper levels of essential minerals, namely air, water, and organic matter, are present in soil, it lacks the ability to be strong. Soil needs just the right amount of moisture, matter, and air to be stable for paving.

Paving Over Soil

You cannot add new asphalt paving material on top of an unstable foundation. And soft soil is unstable. Instead, new asphalt paving solutions need to be considered and chosen. Most of the time, soft soil can be resolved, and once they are, paving projects can continue as planned. Various methods for treating soil instability have proven effective, either on their own or in combination with each other. They include practices such as:

Using drainage tiles to remove excess moisture from soil.

Excavating the soft soil and replacing it with a proper base material.

Tilling and turning the soil to encourage drying or hardening.

Using soil separation fabrics to prevent soil from intermixing with base materials.

Using reinforcement grids (geo grids) to even out the weight of the load.

Tilling chemical stabilization into the soil to change the composition to make it stronger.

Applying foam asphalt injections to mimic the characteristics of pavement.
