We recommend you wait a day or two unless the weather has been very hot. In this case you should give the asphalt an additional two days. If you can avoid turning the wheels when your vehicle is not moving that will prevent major scuffing. If you have had your driveway resurfaced only, depending on the temperature, you should wait four to six hours.
You will always see scuffing on new driveways or roads as it is inevitable. When asphalt is combined with hot weather the surface becomes even more prone to this. In about four weeks the marks will hardly be noticeable as the surface settles. The scuff is actually sand in the asphalt mix being displaced and will eventually wash away. Asphalt takes about six months to fully cure so you should always try to avoid tight turns, sudden stops, and turning the wheels when the vehicles are not moving.
These cracks (fatigue cracks) are the direct result of excessive bending of the pavement surface. Asphalt will fail if subjected to repetitive or excessive bending as from traffic.
The sun’s UV rays break down the carbon in the asphalt oil causing the color to become the commonly seen grey. The oil bonds everything together so when you see the grey it means the oil is breaking down and causing erosion of the asphalt. Also the oil helps keep the asphalt flexible, so when the oil is gone, the asphalt becomes prone to cracking due to lack of flexibility.
We normally see this because there is not enough support next to the road or driveway. This can also happen if the underlying base is washed out. It can help if you avoid driving on the edge. Small cracks can be fixed with rubberized crack filler, but large cracks will need to be cut out and replaced.
There are formulas developed to define the thickness of asphalt based on the traffic weight and frequency. The thicker the asphalt the longer your driveway is going to last. For driveways handling normal flow traffic and vehicles we recommend two to three inches. For heavier vehicles we can determine what depth will be right for you based on your needs. Specific spots can be done thicker for parking as well.
Hopefully never. If asphalt is properly maintained and not abused it can last a lifetime, but if you notice that over 50% of your driveway is cracked and discolored it will have to be fully replaced. Sealing and patching will help keep your driveway good for many years.
As we discussed earlier the oil in the substance binds everything in the asphalt. The coating seal will prevent the sun from breaking down this oil. The seal also helps prevent weather from getting under the asphalt and destroying the base material.
You can seal your driveway one year after installation and then whenever you notice that that the color is beginning turning grey. Under normal circumstances you can drive on the fresh seal 24 hours later.
