Asphalt Paving Good For Water Drainage

Here’s how properly installing your asphalt paving can be good for water drainage:

Right kind of Asphalt

Be Sure You Choose the Right Kind of Asphalt

It’s important for you to know how asphalt paving can be better that concrete before you choose the type of material for your paving. Any type of asphalt is good for water drainage and should definitely be your top choice when deciding to pave your parking lot or roadway. But some types of asphalt are better than others.

As proper water drainage is one of the most important considerations when it comes to installing and maintaining a solid parking lot, be sure you choose the best possible asphalt for your particular needs.

In almost all instances, this is going to be a porous type of asphalt that allows water to adequately pass through the pavement and into a grave base that can filter the water into the underground aquifers.

Use the Slope to Your Advantage

In order to prevent draining water from pooling on the asphalt surface, it should be installed with at least a one percent slope so the water can easily flow away after a big storm.

This will help protect your asphalt paving from serious water damage over time and is something any reputable pavement installer should automatically take care of from Day One.

If your pavement is already existing, however, be sure you stay on top of sealing cracks and patching potholes so that the water that does collect isn’t doing any significant damage.

Be Mindful of Harsh Winter Weather

To keep the water draining well from your asphalt paving, particularly any problem areas, you’ll want to be especially aware of damage that can occur during the harsh winter months.

Nobody wants to be outside for extended periods of time when the weather is below freezing, but it’s absolutely essential in order to keep your asphalt paving in good condition during this time of the year.

If water gets into any existing cracks during the winter months, the damage can be even worse due to freezing conditions. If the temperature is below the freezing point, the crack can expand many times over as the water freezes and unfreezes.

This is where proper drainage is especially important.
