When you have a really long driveway, the type of driveway that is practically a street onto itself, you may be wondering how you can cut the costs of paving it. It may be possible if you can find an asphalt paving contractor who specializes in interlocking concrete. Here is how interlocking concrete works and how it decreases asphalt paving expenses.
The Subgrade Process
Just as you would lay a subgrade of dirt and stone and frame the area you want filled with regular concrete, so you would prepare the same for an interlocking concrete drive. Since this process is almost always the same, the costs for this part of the project are relatively the same for most of the contractors in your area. Given the length of your drive, the price estimate will still be costly, but the interlocking concrete is what brings the final cost down.
Large sheets of pre-fabricated concrete and concrete paving stone are made to lock into position on your drive, and they lock into each other. As the sheets or stones are placed, they are secured with a grout. If there are any curved areas in your long driveway or bends in your driveway, construction may slow until these sections can be custom-made. Once the whole drive is filled with interlocking concrete and secured with grout, your contractor can either leave the drive as is or pave it with asphalt. The interlocking concrete has the ability to absorb a PSI almost four times as much as poured/slab concrete, which is why you may decide to leave it be and not pour asphalt.
How Your Costs Are Decreased
By laying interlocking concrete you decrease your driveway paving expenses through:
- Reduced repairs, which are the result of the strength, durability and pressure resistance interlocking concrete has over poured concrete
- Leaving the concrete as is and skipping the asphalt step
- Creating a continuous level surface over a long stretch that is perfect for a continuous pouring of asphalt and will not halt the asphalt process. No halts in the asphalt pouring process means no lost work time, which means no loss in money paid to a contractor for his or her crew as they await the finishing and drying of another section of poured concrete.
Any asphalt you choose to have poured over the interlocking concrete binds the interlocking concrete sections in one long stretch over your entire driveway and the interlocking sections likewise support and hold together the entire stretch of asphalt. You will see less splits, cracks and pits and are far less likely to see these deformities over a greater period of time than traditional poured concrete topped with asphalt or asphalt over aggregate alone.
