Top Reasons to Not Skimp on the Sub-base of Your Asphalt

The asphalt paving process involves several steps to ensure the best and longest-lasting outcomes. Sub-base installation typically occurs somewhere in the middle of this process, and any asphalt paving contractor can tell you it’s one of the most important tasks of all. The sub-base, made from aggregate material, is essentially the first and foremost layer in the paving process, laid on top of the subgrade (i.e., the natural formation underneath). A sub-base is meant to keep the asphalt level and provide it with additional strength to support heavy machinery and vehicles. Of course, a sub-base must be built from quality materials and applied by professionals in order for it to perform as intended. Let’s go over the top reasons not to skimp on the sub-base of your new asphalt application.

Why You Should Invest in Quality Asphalt

A Strong Sub-Base Supports New Pavement Installations

When gazing upon a newly paved asphalt surface, it can be difficult to imagine what’s going on underneath the smooth, black exterior. If you’re unfamiliar with the many steps asphalt paving services must perform, you might not know that there are multiple layers beneath the paved surface, and that these layers are essential. Without a strong sub-base, the upper layers would have no solid foundation -- instead, they would be at the whim of the natural ground beneath them. Ultimately, this lack of a sub-base would yield a thin pavement that would easily fall and rise with every shift of the earth. So, skipping this step or skimping on materials can spell disaster for your asphalt pavement.

Asphalt Longevity Requires a Solid Foundation

It’s no secret that asphalt roads, driveways, and parking lots need to be strong to withstand regular wear and tear from both foot traffic and vehicle movement. That said, short-term strength is only so valuable -- you also want your pavement to stand the test of time. Starting with a strong foundation helps ensure the ongoing durability of your asphalt pavement. Indeed, a thick, high-quality sub-base can extend your pavement’s lifespan by several years or even decades. Moreover, a reliable sub-base can be reused several times over. So, when it comes to asphalt paving repair or resurfacing, you can keep the sub-base that’s already there, saving you time, money, and hassle.

Sub-Bases Facilitate Drainage and Provide Frost Protection

Quality sub-bases further protect asphalt pavement applications by aiding in drainage and mitigating the negative effects of cold weather. This permeable layer allows water to flow beneath the upper layers of asphalt to mitigate moisture intrusion. And when the ground freezes during the coldest parts of winter and thaws close to springtime, the sub-base material insulates the upper layers of asphalt, protecting them from thermal shock. Ultimately, these added benefits offered by sub-bases make asphalt maintenance less hands-on and reduce the need for extensive repairs.

A Proper Sub-Base Cuts Costs in the Long Run

The three reasons not to skimp on your asphalt’s sub-base mentioned above coalesce into this final consideration: cost reduction. Whether you’re a homeowner, business owner, or both, it’s not practical to hire asphalt services on a frequent basis. When hiring asphalt paving professionals, you want to choose the company that provides the longest-lasting results so you can focus on other things rather than continue throwing money at your driveway or parking lot. While many factors play into these costs, a high-quality sub-base is one of the most prominent. By investing in a thick sub-base constructed from quality materials, you can rest assured that your asphalt pavement will stand the test of time, reducing the amount of time and money you spend on maintenance, repairs, and replacement jobs.
