Asphalt pavement is one of the most common types of pavement for roads and parking lots. More than 90% of the roads nationwide use this material for pavement. You'll also discover more parking lots paved with asphalt over any material. That's because many great things about asphalt make it a great choice. This article will review everything you need to know about asphalt.

Eco-Friendly

One of the fantastic benefits of asphalt is that it's great for our planet. The dark color of asphalt attracts hot UV rays, helping to melt snow and ice during harsh winter months. This reduces the need for salt and trucks to clear parking lots and the fossil fuels they use. Asphalt is also recyclable. According to the National Institute of Health, it's one of the most recycled materials, with about 99% of asphalt contractors reusing it for other projects. Completed asphalt paving helps the environment in ways you may not have thought about previously.

The Binders

Certain materials are used to bind asphalt together. Most of the time, asphalt is not pure asphalt. Instead, it's a carefully thought-out combination of materials designed to ensure durability. Rubber and materials that are flexible, like rubber, are often used. These make asphalt more flexible, so it can withstand heavy loads without cracking like other materials. They also help make asphalt more durable, which is why it can last up to twenty years.

The Climate

Those in the asphalt industry must always consider the local climate to develop specific asphalt mixes that work with the temperature. For example, thermal stress due to high temperatures can result in cracking due to the heat. Scientists who design asphalt mixtures have to consider this. Asphalt contractors must also learn to use the appropriate mixture for specific climates.

Moisture

Moisture can be disastrous for asphalt. Once moisture from rain gets into asphalt, it can slowly deteriorate the asphalt. Proper drainage is something asphalt contractors must always include to ensure that water doesn't sit on top of asphalt. Every paved surface needs seal coating every 3-5 years to help protect it from things like moisture.

Asphalt contractors must learn much about science and engineering to ensure that asphalt is durable. They also consider the environment. Contact Wells Asphalt today to learn more about our asphalt pavement services.
