Potholes are a common, frustrating, and difficult problem for many areas of the nation, especially during wet conditions or in wintertime. It is hard for road crews to perform repairs of these potholes using conventional hot mix methods during rainy or cold months, and the problem will continue to grow until roads are pockmarked. Drivers become frustrated, and damage to vehicles or even accidents can occur as a result. That is why the use of a fast-drying, versatile product can be so valuable. Below is how you can use polymer-modified asphalt to repair concrete surface potholes:
1. Remove as much moisture as possible - Though polymer-modified asphalt will adhere and set in wet conditions, it is best to remove standing water, as this can obscure areas inside the pothole and make it efficiently replace the material. However, if evacuation of standing water is impossible, go ahead and fill the hole with material to force the water up and out.
2. Fill the pothole with polymer-modified asphalt - After clearing the pothole of water, pour a sufficient amount of polymer-modified asphalt into the opening and pack it down with a tamping tool or flat shovel. Be sure the pothole is filled completely and that there is slightly more material in the hole than necessary. Ideally, a small crown will exist once the repair is finished and allow traffic to fully compact the site.
3. Compact the pothole patch - One benefit of polymer-modified asphalt is that it can be compacted via several methods. For road crews who travel from pothole to pothole, their truck can serve as an effective means of compacting the material. If you wish to use this method, simply drive over the repair site multiple times until it is compacted and no loose material remains. Of course, other compaction methods can be used, such as powered compactors and rollers.
4. Blend the repair (optional) - While the repair is permanent and sound after you complete compaction, you may wish to disguise the darker patch to match the surrounding concrete surface. To do so, sprinkle a fine layer of portland cement on top of the patch and spray it with water to create a wet mixture. Next, use a broom to blend the water and portland cement together and distribute it across the patch. Once this dries, the site will be much less visible to others passing by the location.
