Reasons A New Asphalt Pavement Is Just Not Smooth Enough

Reasons A New Asphalt Pavement Is Just Not Smooth Enough

Have you ever driven on new asphalt pavement and felt like driving on a washboard? You’re not alone! It’s the bane of every new asphalt owner’s existence. You wait patiently (or not so patiently) for your new asphalt to cure, and then boom! It’s not as smooth as you thought it would be. Why is that? What causes this rough, uneven ride? And is there anything that you can do to make it smoother?

This blog post will explore why new asphalt pavement can be so rough and discuss ways to improve its smoothness. Stay tuned!

Not Enough Asphalt to Bind the Aggregates:

Liquid asphalt must be soupy and thick to bind the small rocks and gravel (aggregates) together. If there isn’t enough asphalt, or if the asphalt is too runny, the aggregate will not be adequately bound together, and the pavement will be susceptible to cracking and potholes.

Lumpy and uneven asphalt surfaces indicate the insufficient mixing of asphalt and aggregates. Fortunately, adding a new layer of aggregate on top of the old layer can help even out the surface.

Lack of Compaction:

Compaction is rolling the asphalt mixture to force all the air bubbles out. If the mixture is not compacted enough, there will be pockets of air left in the pavement which can cause it to crumble over time.

If you can freely kick the asphalt with your foot and leave a dent, improper compaction occurs.

Lack of compaction can cause the pavement to be:

  • Rough
  • Pitted
  • Uneven
  • Cracked

The only solution is to mill off the top layer of asphalt and start from scratch.

Unsuitable Aggregrate Mix:

Some qualities make an aggregate mix suitable for pavement. You can’t just use any old rocks. The rock needs to be strong enough to withstand the weight of traffic but also porous enough so that water can drain through it. They must also be able to bind together so that the pavement has a smooth surface.

If the aggregate mix is not up to par, it can cause the pavement to be rough and lumpy. There is no way to fix this once the pavement has been laid, so getting it right the first time is essential.

Extreme Weather Condition:

If you’ve been unlucky enough to have your new pavement laid during extreme weather conditions, that can also cause a bumpy ride. The pavement needs time to cure and harden properly, and if it is exposed to extreme heat or cold before it has had a chance to do so, it can become damaged.

Similarly, if it rained heavily shortly after the pavement was laid, it can cause the pavement to soften and become uneven. Therefore, you must constantly be updated with the weather forecast before installing new pavement.

Bottom Line:
