Why should I sealcoat my driveway?
Asphalt pavements are made up of stone (aggregate) fine stone or sand, and asphalt cement. The asphalt cement is what gives the pavement it’s black appearance and is the “glue” that holds everything together.
Have you noticed that new asphalt is jet black but soon begins to fade and in a year or two has turned gray? That’s oxidation. The effects of the sun and rain/snow oxidizing the asphalt cement in the pavement. Given enough time the pavement becomes brittle and has less resistance to the loads placed on it. This can lead to a multitude of problems. Asphalt is a petroleum product so any other petroleum derivatives that contact it will dissolve into the asphalt, weakening or dissolving the asphalt’s “glue like” properties. These substances commonly include motor oil, transmission/power steering/ or brake fluids, gasoline, and perhaps household solvents like some cleaners. It’s common to see asphalt damaged by concrete cleaning products used on a sidewalk but rinsed onto a driveway.
And the other common products mentioned can come from anywhere; a leaking car, oiling the chain on the kid’s bikes, spills while servicing the lawnmower, the list is endless. A good quality sealcoating will protect the asphalt pavement from all these damaging factors while providing the curb appeal of a new-looking black appearance. It’s often overlooked that sealcoating not only seals the harmful elements out but seals the beneficial properties of the asphalt cement in. Many years of research has proven that proper maintenance including sealcoating can double the life of asphalt pavement.
