When your driveway or parking lot is first installed it will have a rich black color over time it will begin turning gray. This is the warning signal that the blacktop surface has become worn, porous and rough. The asphalt binder weakens and looses flexibility, causing the aggregate to loosen and allowing water to penetrate deeper accelerating deterioration. Seal coating and crack filling are the major solutions to combat this also making it look new again.
Black asphalt cement binds the rock in your pavement together. Asphalt has no resistance to the oxidizing effects of the sun and is soluble in petroleum chemicals like fuel and motor oil. The asphalt binder weakens and loses flexibility, causing the aggregate to loosen and allowing water to penetrate deeper accelerating deterioration. Black asphalt cement binds the rock in your pavement together. As it wears away the rock loosens and can be washed away opening the surface. Water builds up beneath the asphalt freeze-thaw cycles cause cracks and cavities to form. This leads to them eventually developing into potholes, hazards, and other damage.
Asphalt has no resistance to the oxidizing effects of the sun’s infrared radiation and is soluble in petroleum chemicals like fuel and motor oil. As it wears away, the rock, too, loosens and can be washed away, opening the surface to water penetration. As water builds up beneath the asphalt, freeze-thaw cycles cause cracks and cavities to form, eventually developing into potholes and other serious damage.
The biggest benefit to maintaining asphalt is the cost. It’s far less expensive to preserve the investment already made in the pavement by maintaining it as opposed to replacing. Asphalt is tied to the gas and oil industries so costs for new pavement rises yearly. Proper maintenance restores the lustrous black appearance of your pavement while locking in the asphalt cement, keeping your pavement young. The top coat of sealer becomes the wearing surface of your pavement. The weight of traffic and the wear of tire treads hits the sealer and not the valuable pavement. Seal coating your pavement every 2 to 4 years will more than double the life of your pavement.
A great perk of asphalt is in the properties of it especially in 4 season states like Michigan. Asphalts deep black color accelerates ice melting, eases snow removal, and beautifies your parking lot or driveway. In addition to sealer hot-pour crack filler, a form of rubber will expand and contract with your pavement through the seasons; which prevents further damage. We always inspect every property to see which cracks need filling before we seal coat.
First, we will clean vegetation, dirt, and debris from all cracks and edges of your asphalt. Then we will blow off the entire area ensuring proper adhesion to the asphalt. Next, we will fill any cracks and small holes with rubber to keep them from growing. Finally, we will apply 2 full coats of asphalt emulsion to the asphalt. After the job is complete we block off entrances and exits so they can’t be driven on. It’s important to stay off freshly sealed pavement for at-least 24 hours.
