What Is the Most Crucial Factor for Asphalt Paving Installation?

What Is the Most Crucial Factor for Asphalt Paving Installation? Many people are not aware of the numerous details that a paving contractor must consider when planning and building a new asphalt pavement. They must evaluate the surrounding terrain to see how runoff from neighboring properties might affect the pavement. Contractors must decide on the type of asphalt that will deliver the best results for the customer’s specific needs. The contractor must also determine how many layers of asphalt will be needed to achieve the proper depth to support the loads that will be placed upon the pavement. These are just a few of the factors that contractors must consider. However, contractors must evaluate the most important factor is the soil at the site where the pavement will be constructed.

Why Is the Soil a Major Factor for an Asphalt Paving Company?

Asphalt pavements are much more flexible than concrete, and their flexibility is one of their major benefits. Asphalt can flex under loads, then rebound quickly. Asphalt pavements can also contract and expand with seasonal temperature fluctuations. However, this flexibility requires a strong supporting system underneath it, and this support system, like the asphalt itself, requires proper compaction to make it as dense and strong as possible. When the soil cannot be compacted sufficiently, asphalt contractors must resort to other means to ensure the pavement’s support system’s strength and stability.

How Does an Asphalt Company Deal With Soil They Cannot Compact?

The first thing that an asphalt paving company will do is to compact the soil as well as they can. Depending on the compaction level, contractors will usually use one or more of the following techniques.

• Install an aggregate base, or increase the depth of the base in the design.
• Install a subbase under the base to provide greater support.
• Depending on the pavement design, they may install a layer of concrete, lime, or emulsified asphalt over the soil, the subbase, or the base to serve as a binder.
• The paving contractor may excavate the site deeper than would be needed for compactible soil. The extra depth could be as little as a half an inch or several inches. The excavated soil is then replaced with soil that can be properly compacted.

If an Asphalt Contractor Fails to Deal With the Problem Soil, What Is the Worst That Could Happen?

The worst-case scenario is that the pavement will require a total reconstruction within a short time. You will see numerous cracks, potholes, alligator cracking, and other signs of pavement distress leading up to the pavement failure. As the damage gets worse, water infiltration will continue to weaken what little support the pavement had. If the damage to the pavement and its foundation is limited to just a few small areas, it may be possible to excavate the damaged pavement and rebuild the foundation. However, if the damaged areas account for more than about one-third of the entire pavement, it is normally more cost-effective to choose a complete reconstruction.
