Asphalt surfaces often show signs of aging and deterioration, especially in areas that experience high traffic volume. This blog post will help increase your knowledge about asphalt deterioration over time and provide some tips on how to extend the life of your surface.
Asphalt And Its Main Components
Asphalt is a mixture of fine stone and bitumen, a sticky black substance derived from crude oil. It is used to pave roads and surfaces like car parks because it is smooth, durable, and weather-resistant.
Asphalt can be mixed with other materials to produce different types of pavement. For example, adding limestone or gravel produces a stronger surface that can withstand heavier traffic.
Asphalt is sometimes mixed with rubber in cold climates to improve its flexibility and prevent cracking in winter. Asphalt comprises around 95% stone and 5% bitumen, although the exact proportions can vary depending on the produced type of asphalt. The main types of stone used are sandstone, granite, and limestone, while the most common type of bitumen is bitumen emulsion.
How Does Asphalt Deteriorate?
Over time, asphalt will deteriorate due to weathering and wear and tear. During higher temperatures, the bonding between asphalt particles weakens, and the pavement becomes brittle.
Additionally, water can seep into cracks in the asphalt and cause further damage. As the asphalt deteriorates, it will become more porous and loose, leading to potholes and other problems.
Signs Your Asphalt Need Replacement
- Cracks: Small cracks are normal, but large cracks can indicate a more serious problem. If left untreated, they can allow water to seep beneath the pavement, causing further damage.
- Potholes: These form when water seeps into cracks and freezes, expanding and weakening the asphalt. They can be dangerous for vehicles and should be repaired soon as possible.
- Uneven surfaces: If you notice that your asphalt is no longer smooth, it may be due to settling or poor drainage. Uneven surfaces can also be a trip hazard.
- Fading: Asphalt that has lost its color or is starting to look dull may be deteriorating. This can be caused by UV rays or chemicals.
If you notice any of these problems with your asphalt, it’s important to call a professional for repair or replacement.
Tips For Maintaining Your Asphalt Driveway
With a little effort, you can keep your driveway looking new for years to come. Here are a few tips:
- First, it’s important to seal any cracks or holes as soon as they appear. Sealing will help to prevent water from seeping in and damaging the asphalt.
- Second, you should regularly sweep away any leaves or debris. Sweeping is an easy way to keep your driveway looking neat and prevent damage from occurring. It also prevents rot and mold from building up.
- Finally, applying a layer of salt before the first snowfall is important if you live in an area with cold winters. Salt will help prevent the formation of ice patches, which can damage the asphalt.
By following these simple tips, you can keep your asphalt driveway in great condition.
