3 Reasons Why Your Asphalt Surface Is Not Smooth

One of the main reasons to pay an asphalt paving contractor for your driveway installation project is the quality of the outcome. You should know that laying asphalt is not easy, and you might encounter complex issues you cannot resolve if doing it as a DIY project. Further, it might result in an uneven surface, which becomes a tripping hazard. Additionally, rough surfaces are dangerous to walk on and troublesome for bikes and vehicles. Here are some installation mistakes that lead to uneven asphalt surfaces and possible solutions for the problem. 

Less Than Enough Asphalt to Bind Aggregate

An excellent asphalt surface starts with getting material mixes in the correct ratios. Note that during the installation, the contractors pour hot asphalt over the aggregate to bind it together and create the pavement. Moreover, when the binder is hot, it is viscous but runny and easily seeps between the particles to make a hard asphalt surface. So, if you pour less than enough asphalt over the aggregate, the binding process will not be as effective, and you might end up with a rough surface. Ultimately, if your road looks lumpy and uneven, the problem could have resulted from the pouring process.

Use of the Wrong Aggregate Mix

It is also possible that the issues with your pavement come from using the wrong aggregate mix. Note that an aggregate with smooth gravel and crushed rocks are ideal for even surfaces. In addition, the perfect aggregate material depends on the climate conditions in your area and other prevalent factors. Hence, you should consult a paving contractor before choosing and installing a specific aggregate. They can assess your driveway and help you pick the most suitable mix.

Less Than Enough Compaction

Compaction can also determine how even or uneven the surface will be after the installation. So, after the hot asphalt pours over the aggregate, you need a way to smooth the surface, and compaction is ideal. For the process, paving contractors use a roller or taper. In this case, rolling pushes down the asphalt to get deeper into the aggregate mix and create a lasting surface. It can also push out all existing air bubbles, creating a smooth and even surface. Remember, repairing asphalt that didn't compact is not simple, and you might have to remove it and install it afresh.

These are the common reasons why asphalt pavements might become uneven. You should speak to a competent paving contractor about your installation or restoration if your current pavement is damaged. They will help you correct mistakes and create a durable and smooth surface.
