Have you ever looked at a pothole and wondered how it got there? Have you ever wondered why they always seem to pop up during the spring? There are actually some very simple answers to those questions. It has to do with weathering and how the weather affects the asphalt and the ground beneath it. Here's what happens to cause those potholes that you try so hard to avoid.
The Rain Comes Down
When asphalt is poured, it dries into a solid sheet on top of the carefully prepared soil. Over time, the asphalt develops small cracks. During light rain showers, the water is able to drain off the asphalt or absorb into the atmosphere once the sun comes out. However, during heavy rainstorms, large quantities of water fall onto the asphalt. When that happens, the water remains on the surface for extended periods of time. That's when the damage starts.
The Water Soaks In
The water that's left standing, finds those small – and not so small – cracks on the surface of the asphalt. Once it finds those cracks, the water begins to soak through to the soil below. Once the soil becomes saturated with water, it's unable to absorb any more. That means there's water on the surface of the asphalt and in the soil below. When that happens, the strength of the asphalt is undermined.
The Car Drives Over
Even during rain storms, cars continue to drive over the saturated asphalt. The weight of the cars causes the asphalt and the saturated soil to compress. When that happens, the asphalt sinks into the soil below, causing potholes to develop. Each time a car drives over the pothole, large pieces of asphalt break off. The result is that the potholes continue getting bigger with every passing car.
Time for Repairs
Once the asphalt is damaged, it will need to be repaired. Most potholes can be repaired with a cold asphalt patch. During the asphalt patching process, cold asphalt is scooped into the hole, one shovel full at a time. The asphalt is then left there to be packed down by passing motorists. As cars travel over the pothole, the cold asphalt is pressed down into the hole. The patch will maintain the stability of the roadway and prevent the pothole from getting bigger.
The next time you see a pothole in the road, you won't have to wonder about it. If you have an asphalt driveway, you can use the same patching technique to take care of potholes in your driveway. Pop over here for more information about roadway repair.Share

Hello, I am Deborah Stillen. My passion for hardwood flooring began at a hotel on my first vacation as an adult. The gorgeous hotel flooring was made of a mix of mahogany, walnut, and teak materials that looked exotic to my eyes. Before that, I had only lived in places with wall-to-wall carpet. Upon coming home, I began to devise a way to cover my floors in wood materials. I became an expert on all of the wood flooring options available on the market today. I also studied different installation techniques and the tools used to create amazing patterns with the wood. My house now features a fine mix of bamboo and recycled wood flooring to create a layout I adore. I hope you can use the information on this site to bring wood floors to your home. Please visit often and learn all you can about wood flooring.
