Materials Used in Driveway Paving

There are a variety of materials that can be used to pave a driveway, from inexpensive gravel to a more expensive natural stone or clay brick driveway paver.

Choosing the right material for your new driveway starts with considering your climate and architectural style. This will help narrow down your choices and expedite the decision-making process. Contact Long Island Driveway Paving now!

8 Stunning Options for Driveway Pavers


A sub-base layer of crushed aggregates is a vital part of any paving project. It provides support to the surface, spreads the load evenly across the subgrade and can eliminate frost heave. It’s also a good idea to add a sub-base when you’re creating a new driveway because it can help prevent the paving from shifting or sinking over time.

Sub-base materials should be strong and durable to ensure that your driveway can withstand the weight of vehicles. It’s also important that they meet strict gradation requirements and be free of contamination. You should avoid using sand as a sub-base because it can easily shift under the pressure of vehicles, leading to cracks and failure over time.

It’s best to use MOT Type 1 (or DOT Type 1) crushed stone for your sub-base. This is a high-quality material that’s tested to withstand the stress of vehicle traffic, and it will provide a strong foundation for your paving. It also drains well, so it won’t pool under your paving and cause problems later on.

MOT Type 1 is available in a range of sizes, so you can choose the right one for your specific needs. For instance, smaller pieces of stone can be used for garden paths, while larger stones are more suitable for driveways and public footpaths.

In addition to providing a strong and stable base, MOT Type 1 crushed stone is also able to bind together when compacted. This helps to reduce the amount of dust produced during construction and makes the entire process faster and more efficient.

The sub-base should be at least 100 mm (4 to 6 in) thick. If you’re laying a driveway, it should be 150 to 225 mm (6 to 9 in) thick. This allows the paving to be covered with an asphalt binder without having to worry about it sinking into the soil or becoming unstable.

A sub-base is required when you’re constructing concrete pavements, but it’s not always necessary for other types of paving. The need for a sub-base depends on the frequency of heavy truck loadings, and performance studies can help you rationally decide whether or not a sub-base is necessary for your project.

The asphalt binder is a thick liquid or semi-solid form of petroleum that’s combined with additives and modifiers to improve its performance. It plays a critical role in the longevity and durability of the entire asphalt pavement structure. Choosing the right type of asphalt binder can help resist rutting, cracking, and aging, among other degradation mechanisms. Various national and international standards define the criteria that asphalt binders must meet.

For instance, asphalt binders must have certain properties at different temperatures in order to work effectively in the field. However, standard test methods used to evaluate the performance of these materials require careful temperature control in order to provide meaningful data. This complication led to the development of the performance grading system, where asphalt binders are graded based on their ability to perform at the expected temperatures of a project site.

This system allows engineers to select asphalt binders that are most suited for their projects, and can extend the lifespan of their resulting roads. This is a vital step in the road construction process, as the wrong asphalt binder can have a direct impact on how well the final pavement withstands stress and traffic loads.

Various other factors also influence the choice of an asphalt binder, including cost and environmental sustainability. The demand for high-quality asphalt binders that can withstand the challenges of climate change is fueling the development of new and improved formulations. Some of these innovations include additives that are derived from renewable resources and can help reduce the carbon footprint.

Another consideration is the versatility of an asphalt binder, which must be able to adapt to the changing needs of road infrastructure. For example, the addition of polymers can enhance the asphalt’s ability to bind with aggregates, improving its resistance to temperature fluctuations and environmental wear and tear. Likewise, the use of modifiers can enhance a pavement’s elasticity and allow it to better withstand heavy traffic loads. This increased flexibility can help reduce maintenance costs and extend the life of a road.

As the name suggests, this is the layer of asphalt that sits on top of the aggregate base and binder. This is the layer that gives your driveway its strength and durability. It is made of smaller aggregates that are coated with liquid asphalt cement. It is raked and compacted by the paving contractors to make it smooth and even.

It takes only a few days for asphalt to fully cure. This is considerably shorter than the time it takes for concrete to set up, and it cuts down on long construction periods. Using asphalt also means that your driveway will be ready for traffic sooner than other types of paved surfaces, such as gravel.

One of the benefits of paved asphalt is that it is unaffected by salt. This means that you will have fewer worries about snow removal and road ice damage when the temperatures drop. Asphalt also offers flexibility for your driveway surface, which is beneficial if any sort of ground settlement occurs.

When choosing a driveway surface for your home, think about the look you want to create. Would you like a modern appearance, with clean lines of block or slate paving? Or do you prefer a traditional look, with cobbles or setts in alternative colours? If you are not sure, it is always best to consult with a paving specialist.

You may also want to consider the type of drainage you would like. This will have a direct impact on the surface of your new driveway, and it is important to ensure that your contractor plans and builds adequate surface slopes to produce good drainage. Standing water, known as ponding, on your driveway can cause serious problems.

It is worth considering whether you need to raise any water valves or sewer inlets before having your paved driveway installed. This will affect the overall cost of your project, and it is important to know who is responsible for ensuring that these are raised before the application of the Stage II topcoat. It is a good idea to discuss this with your paving contractor before starting the job.

When constructing your asphalt driveway, there are areas that need special attention to make a smooth transition between the driveway and walkways, garages, streets or other pavement. These transitions are known as butt joints and need to have proper grading to ensure that the surface is safe for vehicles or pedestrians to go from one to another.

The first thing that needs to be done is to remove the existing pavement and grade the soils under it. This step helps to eliminate any dips or low areas in the driveway, and also prevents rutting and premature cracking of your new asphalt surface. The grading process is often done by hand, and the topsoil should be tamped down to give the area some stability.

Once the sub base is in place, it’s time to add the binder layer. This is a black mixture that’s made from small aggregate, oil and sand. This is what gives your driveway that jet-black appearance and offers a great texture to your driving surface. This layer is then spread over the surface and compacted thoroughly to make sure it stays in place.

As a finishing touch, most driveways are surrounded by edging and borders to help add a professional look to your home. This is a great way to accent your driveway, and it’s also easy to change the color of these edging and borders. Current trends are leaning towards choosing a paver color that ties in with the roof colors of your home in the primary paver field and in the border, but you have many choices to work with.

While the overall process of installing a new driveway can seem lengthy, it’s important to remember that these steps are necessary to ensure your driveway has a long life. Asphalt is known to hold up better than other paving materials like gravel and concrete in harsh weather conditions, including snowy winters. In addition, it’s easy to repair when the need arises and can withstand heavier vehicles than other materials. This makes your new driveway a smart investment for your property.
