Correctly estimating the thickness of the asphalt layer is a critical aspect of asphalt paving. There isn’t a single “right” answer for how thick the pavement should be, but there are many factors that contractors take into account when determining what is best for their customers’ needs.
Consider the climate and geographical location of your property. Does it receive a lot of snowfall? In this case, you may need more asphalt to protect from rutting in the winter months. Do you live close to an airport or military base where aircraft noise is common? Then thicker layers might help dampen the sound.
As experienced contractors, Surface Solutions in Salisbury considers various factors to determine the best asphalt thickness for our projects. Over the years, we have worked on some stellar asphalt projects and our experience and expertise have enabled us to estimate the surface thickness levels quickly. In this blog post, we’ve compiled some important factors that our professionals consider before making the final call on the level of asphalt thickness.
1) Check the Sub-Base
The sub-base is the foundation that supports a pavement. The road base and the asphalt are then laid on top of it, so if there is any weakness in this layer, it’s unlikely that you will get effective coverage for your surface. Whether you’re working with a compacted or an aggregate base, the type of sub-base determines the thickness of the asphalt surface. Your pavement will deteriorate without the proper subbase preparation, which will call for significant repairs or complete replacement.
2) Know the Soil Type
We’ve also noticed that some soil types require more asphalt than others. For instance, heavy clay or loam soils will take up a lot of the product when compacted and need to be treated with additional material for stability. On the other hand, sand-based sub-bases are so light in weight that they don’t require extra material.
Knowing about the intended use of the pavement is one of the most critical factors contractors consider when determining asphalt surface thickness.
A residential driveway does not require the same thickness as a commercial driveway.
Different types of asphalt surfaces will also have different thicknesses, such as hot mix and cold patch.
Suppose the asphalt pavement is being installed in an area with a high risk for extreme weather conditions. In that case, contractors might adjust their calculations accordingly to allow the surface to withstand harsh winters or droughts while maintaining stability during other seasons.
As you can see, there are many factors to account for when determining the thickness of the asphalt surface. As a contractor, you must know how much material is needed before beginning any work on your project. That way, both parties end up pleased with the outcome!
