Porous asphalt is commonly used in parking lots to ensure proper water drainage. Porous asphalt maintenance aims to prevent the pavement surface and underlying filtration structure from becoming clogged with fine sediment. Porous asphalt structures can last 20 years or more with adequate routine maintenance services. Our experts on asphalt paving in Jackson, CA, offer the following tips for maintaining your porous asphalt paving:
It would be best if you vacuumed a porous parking lot paved surface at least biannually with a special vacuum sweeping machine. Standard broom sweepers are discouraged from use on porous asphalt because they will cause dirt and debris to become lodged into pavement pores. Instead, a vacuum sweeper provides a high-volume air blast that forces air out at an angle, causing any debris to come loose from the asphalt surface to be vacuumed into the machine.
When porous pavement becomes severely clogged where vacuum sweeping will not restore it to proper drainage, washing it with clean low-pressure water followed by vacuuming it again immediately. It is essential to use a low-pressure nozzle to not force contaminants and debris further into the porous material. This is essential to remember, as other asphalt surfaces benefit from pressure washers for cleaning and stain removal, so do your best not to confuse the two.
Maintaining any landscaping adjacent to the porous asphalt pavement is vital to prevent soil from washing out onto the paved structure. If soil washout does occur, it is critical to clean the paving immediately to prevent pore clogging.
Be certain not to use abrasives and sand for winter maintenance because it will clog your asphalt pores. Instead, use standard road salts and other deicing materials. There is rarely a need for plowing in California, but in other areas, it is essential not to set the blade too low. If you need to plow a porous asphalt structure, the plowing blade should be set about an inch higher than the setting used for other areas.
If your porous asphalt surfaces have damages that require repairs, you can use non-porous paving materials to fix damages involving less than a cumulative 10% of the pavement surface. However, it would be best to patch up areas more significant than 10% with approved porous asphalt materials.
Porous asphalt requires different maintenance measures than traditional asphalt structures. You can maintain porous asphalt structures by vacuuming them regularly and washing them as needed. In addition, it is essential to maintain adjacent landscaping and use care with winter snow and ice removal tactics.
