Advantages of Seal Coating an Asphalt Pavement

A typical asphalt pavement is made up of bituminous, rock, sand and stone base. All of these are hold on together by a binding agent like by product of crude oil. As the time passes this agent loses its binding ability due to the temperature changes, rainfall, tree roots, and many more. Unfortunately this ends up in creating cracks and potholes. This degrades the pavement. People put protective layers on their pavements to save them. Seal coating is a commonly used name of this protective layer. This layer also gives a beautiful glazy look to the pavement.

The climate of Michigan has a deep impact on the asphalt pavements here. The hot and cold temperature condition easily creates cracks in the pavements. Paving contractors in Michigan are fully aware of this fact. That is why they always emphasize on putting a protective layer on the asphalt pavement in regular interval of two to three years in average.

Residential asphalt companies in Michigan can help you to take care of this coating against small fees. Also this will protect the pavement from potholes, sand, and car oil, ultraviolet rays of sun and compression and expansion effects due to temperature changes.
