Asphalt Is Only as Good as the Base It’s Built On

Any new installation or home improvement project you undertake to enhance your house can only be as good as its design. This is especially true when it comes to the laying of new asphalt for a driveway. Regardless of what type of asphalt mix is used or how well it is laid by your asphalt contractor in Lufkin, TX, if it is not built on a solid base, it is only a matter of time before your driveway will start to give you major problems. Here are a few of the key components that are necessary before any new asphalt construction can begin.

Preparing the subgrade

Before the hot mix of your asphalt can be poured, your contractor will have to make sure that the ground underneath your new installation is ready to support your driveway. The asphalt itself will be flexible so as to allow for small expansions and contractions that happen naturally as the temperatures change, so a solid base will be necessary to provide the rigidity needed to support the concentrated weight of heavy vehicles such as cars and trucks.

Even though there will be different strength characteristics that correspond to different types of soil, if asphalt is laid on top of soft soil, the foundation will lack real strength, and you will experience deformities that weaken your driveway as a result. This means that soft topsoil, wet or soggy clay and any roots or debris will have to be removed before the foundation can be laid.

Using the right materials

Many different resources have been used to reinforce the subgrade, but one of the strongest materials that can be used for long-lasting driveways is high-graded, quality gravel or rock. It is important to make sure that this gravel is well compacted, which will help to fortify and stabilize the construction.

Proper drainage is a must

Even after your subgrade has been laid, you are not in the clear just yet. In order to ensure that the base of your asphalt driveway remains intact for many years to come, it is imperative that a proper drainage system is in place. Just as excessive dampness can prematurely deteriorate asphalt over time, water removal is just as important for the subgrade under your asphalt as well. Your contractor will have to lay the gravel just right in order to allow the water to naturally trickle out when exposed to adverse weather conditions.
