Every well-constructed asphalt driveway begins with the preparation of subgrade. It is extremely important for a driveway that is durable and long lasting. One of most important parts of the grading process is addressing the drainage or water run off. Without it, moisture will collect and break up the asphalt over time. We excavate the soil and fine grade quality sub-base materials to ensure proper water drainage, as well as assist it with the right slope.
To stabilize the subgrade we apply a strong base material made of recycled concrete. Then, we utilize a pneumatic roller for proper compaction. Heavy machinery is vitally important in making sure the asphalt has a strong asphalt foundation. To minimize vegetation growth, we can apply a herbicide to the soil. This can aid in the prevention of weeds growing up through the asphalt can cause cracking and other significant damages over time.
In large applications, to ensure a consistent depth of asphalt throughout the blacktop driveway, we might use an asphalt paver machine to lay down the aggregate. Without this type of heavy machinery on large projects, the surface could end up with an uneven, bumpy surface.
As the asphalt is being laid from the blacktop paver machine, the asphalt is raked and compacted while the asphalt is still hot. If the asphalt isn’t compacted well enough, it will allow water into the pavement and lead to it breaking apart. If it is compacted too much, the asphalt may stretch and crack, leading to pavement failure.
After laying the asphalt and compacting it, we tamp the edges and pull some of the surrounding subgrade up to it. This makes the driveway appear more naturally to it’s surroundings.
