Preparing the area before asphalt paving : is it necessary?

5 May 2023

Asphalt paving is a crucial step in completing your driveway and other paved surfaces. To ensure a quality and long-lasting result, preparing the area to be paved is essential. However, there may be confusion as to whether homeowners should be responsible for preparing the area or if it is the responsibility of the asphalt paving company. In this article, we will examine why it is important to prepare the area before asphalt paving and clarify who is responsible for this step.

Area Preparation

Preparing the area before asphalt paving ensures that the paved surface will be solid, durable, and functional. Adequate preparation ensures optimal asphalt adhesion, efficient drainage, and avoids long-term stability issues. A well-prepared surface also ensures a faster and more efficient installation of the asphalt.

The first step in preparing the area is to evaluate the condition of the existing soil. It is important to ensure that the soil is well compacted and free of any organic material. If the soil is inadequate, it may require correction, such as the installation of an appropriate base layer to reinforce soil stability. This soil preparation step is typically done by an excavation or grading company, which has the expertise and necessary equipment to do this work safely.

Area Drainage

Next, it is essential to consider the drainage of the area to be paved. Proper management of rainwater is necessary to avoid water infiltration problems and premature deterioration of the asphalt. An appropriate slope should be provided to allow rainwater to flow away from the paved surface. This drainage preparation step is also typically done by companies specializing in drainage work.

Creating a Solid Base

Once the soil and drainage are considered, the area preparation continues with the creation of a solid base layer. This layer, typically composed of crushed gravel, must be well compacted to ensure the stability of the paved surface. The height of the base layer should be determined based on the type of traffic expected on the paved surface. For high-traffic areas, a thicker base layer will be necessary. Creating the base layer is usually done by an excavation or grading company, which has the expertise and necessary equipment to do the work appropriately.

In conclusion, it is essential to prepare the area before asphalt paving to ensure the quality and durability of the paved surface. Adequate preparation includes soil evaluation and preparation, drainage management, and the creation of a solid base layer for paving. Although responsibility for area preparation may vary, it is recommended to work closely with the asphalt paving company to ensure that the area is properly prepared in accordance with industry standards.
