Most commonly asked questions about care and maintenance of new asphalt driveways.
When the weather is hot, usually 75 degrees or more, it will take asphalt a long time to set up. Ordinarily, you can drive on it after five days. This means that you can go in and out of your garage, but we recommend that you do not park on it for at least two weeks. The sun will draw the natural oils of the asphalt to the surface, making it soft. This is part of the natural curing process for your driveway. It will take approximately one year for your driveway to be completely cured.
On hotter days, there is a potential for tire marks to appear. The tire marks will go away with continuous compaction by routine driving. WARNING: Do not turn your tires if the car is not moving. Marks that might be left by the roller or rough edges will appear as the driveway is compacted by continuous driving.
In Minnesota, the frost penetrates the ground as deep as 6 feet. The ground, when frozen this deep, will heave oftentimes as much as 2 inches. Asphalt will give to a certain extent, then crack. No matter how strong the asphalt pavement is constructed, the forces of nature are stronger. This is a normal situation and is not necessarily damaging to the life expectancy of a residential driveway.
Your driveway has been laid with a paving machine, but there are some spots that were finished by hand. In the spots where handwork was done, the rocks will come to the surface. A sealcoat will smooth out any exposed rocks.
Sealcoating will fill any expansion cracks and will protect your driveway from damaging elements. Generally, sealcoating is done within the first two years after installation. After the initial sealcoating, it is recommended that you do not apply another sealcoat more than every three years. Sealcoating your driveway too often can cause excessive build-up, resulting in a checkered look.
Petroleum products such as gas and oil, and sharp objects such as bicycle kickstands, grill legs, trailer hitches and jacks, are all common enemies. When storing a trailer with a jack, place a small piece of plywood underneath the hitch or stand. Heavy vehicles such as garbage trucks, heavy trailers, and construction equipment can also be detrimental to the life of your driveway.
