Asphalt contractors play a crucial role in maintaining and repairing home driveways. When digging up, repairing, and replacing asphalt driveways, they follow a systematic process to ensure a smooth and durable result.
Firstly, the contractors start by excavating the existing driveway. It involves removing the asphalt’s top layer and any damaged or deteriorated sections.
They use heavy machinery, such as excavators or bobcats, to carefully dig up the old asphalt, ensuring that the base layers are not disturbed.
Once the excavation is complete, the contractors assess the condition of the underlying base layers. If any damage or instability is detected, they repair or reinforce the base to provide a solid foundation for the new driveway. It may involve compacting the soil, adding gravel, or installing a geotextile fabric to enhance stability.
Next, the contractors prepare the site for the new asphalt. They ensure proper drainage by grading the area and sloping it away from the house. It helps prevent water accumulation and potential damage to the driveway. In addition, they may apply a tack coat, a sticky adhesive substance, to promote adhesion between the old and new asphalt layers.
Finally, the contractors lay the new asphalt using specialized equipment.
From excavation and base repair to proper drainage and application, asphalt contractors ensure that the process is carried out efficiently, resulting in a durable and visually appealing driveway.
