Blacktop Facts


Safety Standards





If you would like additional information please call



1. How many inches of blacktop do I need?
The thickness of blacktop depends on how you use your driveway. For a typical residential driveway, we recommend 2 ½ inches (compacted) of ID-2 wearing blacktop. For a heavier traveled driveway we would recommend 2 inches (compacted) of a binder course then apply 1½ inches (compacted) of ID-2 wearing blacktop.

2. How important is the sub-base in my driveway?
The sub-base is the most important part of any paved surface. An adequate sub-base involves the construction of a six to eight inch (compacted) crushed stone base after all the topsoil is removed. Most failures to the blacktop are due to failures of the sub-base.

3. What is the weakest part of any driveway?
The weakest part of any driveway is typically the edges, due to the fact that there is nothing to support the shoulder of the asphalt. With no support, the asphalt edges are subject to cracking or breaking. We recommend that you support the edges with a material such as topsoil or stone after you have any paving work done.

4. How long does it take for blacktop to cure?
It typically takes about one full year for blacktop to cure and get very hard, but you can still scuff the surface of the blacktop—especially on very hot, sunny days when the blacktop is somewhat pliable.

5. Do tire scuffs hurt my driveway?
Scuffing can occur on hot summer days when blacktop gets somewhat pliable. Tire scuffs do not actually hurt the integrity or the longevity of your driveway. Scuffing simply scratches the oil and some of the smaller stones off the surface.

6. Can I help prevent tire scuffs?
Turning your tires on blacktop when you're not moving causes tire scuffing. You can help prevent tire scuffing by making sure that your vehicle is moving when you turn your wheels. Also try to make more sweeping turns instead of short, sharp turns. Another trick you can try is to water down your blacktop before driving on it. Wetting your blacktop helps your tires to actually slip somewhat on the blacktop instead of scuffing it.

7. How long must I stay off of my driveway after it is paved?
During normal conditions, we recommend a waiting period of three to five days. In extremely hot conditions, we recommend you refrain from using your driveway for as long as possible.

8. What should I look for in a paving contractor?
When choosing a paving contractor, there are a few things to consider: Make sure the contractor considers details such as tree roots, shrubs, power lines and water drainage. One of the most important factors is to make sure storm water runs away from your house or building. Be sure to receive all quotes in writing. Your contractor should have a written proposal and detailed plan. Be sure the proposal includes details on the sub-base preparation, the quantity of blacktop (usually given in compressed inches), the type of rollers they plan to use, the available warranty, and most importantly, if the contractor is insured.

9. Is price the biggest decision maker?
The price is always a factor when choosing your contractor, but price is not the only factor to consider. Quality, reputation, professionalism and workmanship are also very important when selecting a contractor. Problems and substandard results are typically a product of poor workmanship. The importance of attention to detail and proper procedure in construction cannot be overemphasized.
