Meanwhile, check out this handy checklist of preventative maintenance for both commercial and residential asphalt paving.
As one of the best preventative maintenance methods for pavements, crack filling aims to reduce the seepage of water into pavement cracks. When water infiltrates your pavement, the aggregate base and subgrade materials are weakened by moisture, and as result, your pavement gets destroyed over time.
Crack filling involves blowing out the cracks and cleaning them, and once they are clean, crack filler material is installed to cover the gaps. There are several choices for crack filler materials, such as:
- Asphalt emulsions
- Polymer-modified emulsions
- Fiberized asphalt
- Asphalt cements
Each of these materials varies in performance and price. Generally, crack filler materials last for no more than three years, after which you have to perform crack filling once again. This makes crack filling ideal and affordable for the short-term, before you plan for a major pavement rehabilitation.
For long-term preventative maintenance of your pavement, you can consider crack sealing.
Instead of just filling the cracks, this procedure involves routing them. During the crack sealing process, cracks in your pavement are ground in a way to create small squares, which act as deposit for crack seal material. The process completes with the overbanding of the crack seal material over the top of the cracks (though this varies with local preference). Crack sealing proves effective during thermal changes. Done correctly, crack sealing applications are good for up to 5 years.
Materials used for crack sealing usually include rubberized asphalt. These are highly cost-effective. Moreover, crack sealing materials are designed according to temperature ranges, which means you should use rubberized asphalt that suites the climate conditions in your area.
Moisture and sun exposure are just a few of the factors that can damage a paving project. Seal coating is another preventative maintenance process that can help preserve your pavement. You can get your pavement sealed if there are cracks or the surface sand is wearing out, or even if you notice a change in the color of your paving. However, seal coating has to be maintained every two or three years.
Depending on the type of pavement being coated, you can choose between coal tar emulsions or asphalt emulsions as coating materials. Among these asphalt emulsions involve fewer odors and reduce the risk of skin burns or irritation.
These are some of the ways in which you can perform pavement maintenance. Of course, you also have clean your pavement every few weeks to remove dirt and debris. Regular cleaning of the pavement will also help you detect cracks in their early stages.
To sum up, protecting your pavement from forces of nature can add years to its life. For homeowners especially, pavement maintenance also serves an aesthetic aspect. Imagine driving into your home, only to be welcomed by cracks, chips and potholes!
