New Asphalt Installation

---

1. Plan Your Project

The first step to successfully laying a new asphalt driveway is to plan your project. You will need to determine the size and shape of your driveway and how much asphalt you will need to purchase. Before starting your project, you must also have all the necessary tools and equipment.

2. Choose the Right Location and Size

The next step to successfully laying a new asphalt driveway is to choose the correct location. The location should be level and well-drained, as water can cause the asphalt to crack and crumble. Additionally, the location should be large enough to factor in the size and design of the new driveway.

3. Prepare the Subgrade

Once you have chosen the location and size of your new driveway, you will need to prepare the subgrade. The subgrade is the layer of soil that lies beneath the asphalt. To prepare the subgrade, you will need to remove any vegetation, organic material, and loose or uncompacted soil. Once this has been done, you will need to compact the subgrade with a roller compactor.

4. Install a Subbase

After the subgrade has been prepared, you will need to install a sub-base. The sub-base is a gravel layer that helps support the asphalt and prevent it from cracking. To install the subbase, you will need to spread a layer of gravel over the prepared subgrade and compact it with a roller compactor.

5. Install a Drainage System

If needed it is also essential to install a drainage system before laying the asphalt driveway. A properly installed drainage system will help to prevent water from pooling on your driveway and causing damage. The most common type of drainage system for an asphalt driveway is a French drain, consisting of a perforated pipe buried beneath the gravel in the subgrade layer.

6. Install Hot Mix Asphalt 

Once the sub-base has been installed, you will be ready to install the asphalt. It can be done by hand or with a machine called an asphalt paver. When installing hot mix asphalt, it is crucial to ensure it is installed in a timely manner at high heat temperatures to ensure level and smooth appearance. It is essential to spread the asphalt evenly so it is of consistent thickness throughout your driveway. A standard thickness for an asphalt driveway is between two and four inches.

7.Compact Asphalt Paving

After spreading the asphalt, you must compact it to adhere correctly to the base layer. Packing the surface can have a hand tamper,  a gas-powered plate compactor and a roller compact machine.  It is crucial to compact in a quick timely manner and not to over-compact the asphalt, as this can cause cracks or divots in its surface.

8.Allow Curing Time

After compacting, the asphalt must allow cure time before using your new driveway. Cure time allows for proper adhesion between the base layer and the new asphalt driveway surface; without it, your driveway may not last as long or perform as well as it could. Depending on weather conditions, the cure time can take anywhere from 24 hours to several weeks. Check with your local paving contractor for guidance on how long the cure time should be in your area.

9.Seal Asphalt Paving

To protect your new driveway and extend its lifespan, you must seal it with an asphalt sealer. It helps to fill in any cracks or voids in the pavement and prevents water from seeping in and causing damage. Sealing should be done every 1-2 years or as needed depending on weather conditions and wear and tear.
