Paving contractors follow a precise process to ensure your driveway is durable, level, and visually appealing. The first step involves removing the existing driveway using a skid steer with a tooth bucket. This tool carefully pries up the old asphalt without damaging the underlying dirt and rock, known as the sub-base.
Preserving the integrity of this compacted sub-base is crucial, as it provides a solid foundation for the new driveway.
Once the old asphalt is removed, the edges of the driveway are straightened using ropes, paint, and tools like a mattock or shovel. This ensures clean lines for the new pavement. Next, the sub-base is leveled using quarry-processed stone. If the sub-base is already compacted, only a thin layer of stone is added to correct any uneven areas and ensure proper drainage.
The leveling process is further refined by using an asphalt paver in a dry run, which compresses the stone and smooths the surface. Before paving, the sub-base is compacted with a tandem roller to prevent sinkholes. Finally, hot asphalt is laid down and spread evenly across the driveway. The asphalt is then compressed and smoothed using rollers and a plate compactor, creating a uniform, durable surface. The result of the hard work from your paving contractors is a smooth, well-graded driveway that is ready for years of use.
