Despite our best efforts, cracks and then potholes will almost always form over time. Most potholes are caused by water in the cracks turning to ice in the winter. You can slow their progress with a crack seal.
Crack seal is hot rubber that is poured into asphalt cracks. When it cools it adheres to the asphalt sealing the cracks against moisture. By filling the cracks with hot rubber before they form potholes, you will seal water out and dramatically extend the life of your asphalt. When done properly, crack seal can extend the life of your asphalt and save you money.
