What Is Asphalt and Why Is It Used In New Zealand?

Definition and Uses of Asphalt

Asphalt is a versatile and widely-used construction material, primarily composed of bitumen and aggregates. Bitumen is a thick, sticky substance derived from crude oil, while aggregates refer to a combination of sand, gravel, and crushed stone. When mixed and heated, these components form a durable, flexible material ideal for a range of paving projects. In New Zealand, asphalt is a popular choice for constructing driveways, roads, parking lots, and other paved surfaces.

The reason asphalt is so commonly used in New Zealand boils down to its strength and resilience. The country’s varying climate, with regions experiencing heavy rainfall and others subject to extreme sunlight, requires a paving material that can withstand the elements. Asphalt fits the bill, offering strong resistance to both wear and weather-related damage. Its ability to adapt to temperature changes without cracking makes it an ideal choice for a range of infrastructure projects.

Advantages of Using Asphalt

One of the main reasons asphalt is so commonly preferred for paving in New Zealand is its cost-effectiveness. Compared to other materials, asphalt is affordable to install and offers excellent long-term value. It’s not only cheaper to lay down but also provides a quicker installation process, meaning less disruption during road or driveway construction.

Asphalt also stands out for its longevity. A well-installed asphalt surface can last for decades with minimal upkeep, making it a low-maintenance option for busy streets, driveways, or commercial parking lots. Over time, any minor cracks or wear can be easily repaired, further extending the material’s life.

Another significant advantage is asphalt’s eco-friendliness. It’s one of the most recycled materials in the world, which is a major benefit for sustainability-conscious New Zealanders. When an asphalt surface reaches the end of its lifespan, it can be removed, crushed, and reused in new paving projects, reducing the demand for new raw materials and minimizing environmental impact.

Asphalt’s durability, affordability, and environmental benefits make it an ideal paving material for New Zealand’s roads, driveways, and other surfaces. Its resistance to weathering and ability to withstand New Zealand’s climate make it a smart, long-lasting investment for both public infrastructure and private projects.

Average Asphalt Cost Per Square Metre In NZ

Current Market Overview (2024)

In 2024, the average cost of asphalt per square metre in New Zealand typically ranges between $50 and $200. However, this price can vary significantly based on several factors such as the quality of asphalt, project size, and geographical location within NZ. For smaller residential projects, like driveways or pathways, you can expect to pay closer to the lower end of this range. On the other hand, larger commercial or industrial jobs, which may require more durable, higher-quality asphalt, can push the price up toward the higher end. Additionally, regions with higher transport or labor costs, such as rural areas, may also see increased pricing compared to urban centres.

The type of asphalt used also plays a key role in determining the final cost. For example, a basic asphalt mix might be more affordable than a more advanced blend designed for heavy traffic or extreme weather conditions. Therefore, when considering the overall cost of asphalt, it’s essential to account for not just the base price but also the specifics of your project and the asphalt type best suited for your needs.

Comparison to Other Surfacing Materials

When compared to other common surfacing materials like concrete, gravel, or paving stones, asphalt often stands out as a cost-effective and durable option. Concrete, while extremely durable and long-lasting, typically costs more to install, with prices often exceeding $200 per square metre, depending on the finish and reinforcement required. Gravel is certainly a cheaper option, costing as little as $10 to $30 per square metre, but it lacks the stability, durability, and smooth finish of asphalt, making it more suitable for temporary or low-traffic areas.

Paving stones, another alternative, provide an attractive and customizable finish but at a much higher price point. The cost of installing paving stones can range from $100 to $250 per square metre or more, depending on the material and complexity of the design. While aesthetically appealing, paving stones require more maintenance and are susceptible to shifting over time, especially in areas with heavy traffic.

Why Asphalt is a Better Value Option

Asphalt is often considered the best value for many projects due to its affordability, durability, and relatively low maintenance costs. For most people, asphalt provides a balance between cost-effectiveness and long-term performance, especially for driveways, parking lots, and roads. It offers a smooth, resilient surface that can withstand the rigours of heavy use, and with proper care, an asphalt surface can last for 15 to 20 years or more. Additionally, asphalt is quicker and easier to install compared to concrete or paving stones, meaning reduced labor costs and less disruption during the project.

In summary, while there are cheaper options like gravel, and more decorative options like paving stones, asphalt presents an optimal solution for those looking for a durable and cost-effective surface in New Zealand.

Key Factors That Affect Asphalt Pricing In NZ

When planning an asphalt paving project in New Zealand, several factors influence the overall cost. Understanding these can help ensure you’re making informed decisions that align with both your budget and the quality of the final result. Let’s break down the primary elements that affect asphalt pricing across the country.

1. Size of the Area to be Paved

The size of the area you’re planning to pave is one of the most critical cost determinants. In general, larger areas often come with reduced per-square-metre costs. This is due to economies of scale—once the machinery and crew are on-site, spreading asphalt over a larger surface doesn’t proportionally increase labor or material costs. For example, paving a large parking lot may be more cost-effective on a per-metre basis than a smaller driveway, as equipment setup and fixed costs are spread over a bigger area.

2. Thickness of the Asphalt Layer

The thickness of the asphalt layer you require will also impact the cost significantly. For most residential driveways, a standard thickness of around 25mm is sufficient. However, surfaces subjected to heavy-duty use, such as roads or industrial areas, may require a thicker layer of up to 40mm or more. Thicker layers demand more material and labor, raising the overall price. Additionally, the type of traffic your surface will endure is important to consider when determining the appropriate asphalt thickness.

3. Location and Access to the Site

Geographical location can influence asphalt pricing due to the differences in labor, transport, and material costs. For instance, urban areas tend to be more cost-effective as materials and labor are readily available. In contrast, rural locations may see higher prices due to transportation costs and limited accessibility. If your site is difficult to reach or requires special equipment to access (such as hilly or remote areas), this can add to the overall project cost. Easy access to the site generally keeps prices lower, while difficult-to-reach areas can drive up both labor and transport expenses.

4. Type of Asphalt

Not all asphalt is created equal, and the type you choose can have a big effect on pricing. The most common types include hot mix asphalt, cold mix asphalt, and permeable asphalt. Hot mix asphalt, typically used for driveways and roads, tends to be more durable and provides a smoother finish, but it can be more expensive due to the need for specialized equipment and timely installation. Cold mix asphalt is less expensive upfront and is used for quick repairs, but it may not last as long. Permeable asphalt, designed to allow water drainage through the surface, is a premium option often used in environmentally conscious projects, and its installation requires more expertise and higher material costs.

5. Base Preparation and Existing Surface Condition

The condition of the existing surface and the preparation needed to create a solid base can significantly affect asphalt pricing. If your site needs extensive excavation, leveling, or removal of existing materials, the cost will rise accordingly. A poorly prepared base can lead to premature cracking and deterioration, so investing in proper site preparation is crucial for the longevity of the asphalt. Depending on the site’s condition, extra work such as grading, compacting, or adding base layers may be required, adding to the total cost.

6. Drainage and Water Runoff Considerations

In New Zealand, where rainfall can be frequent, especially in certain regions, drainage considerations are critical. Proper drainage prevents water from pooling on the surface, which can cause damage over time. Installing proper water runoff systems, such as drainage channels or sloping the surface, may increase the overall cost but is essential for extending the lifespan of your asphalt surface. Skimping on drainage solutions can lead to costly repairs down the line, as water damage is one of the leading causes of asphalt deterioration.

Asphalt pricing in New Zealand is influenced by multiple factors, from the size of the area and the type of asphalt to site accessibility and drainage needs. By considering these key factors, you can better estimate the cost of your project and ensure you’re getting the most value for your investment. Whether you’re paving a small driveway or a large commercial space, understanding these elements will help you plan a successful, long-lasting asphalt installation.

For example, if you are paving a driveway that’s 10 metres long and 10 metres wide, the total area would be:

• 10metres × 10metres= 100 square metres

2. Consider Base Preparation  

Before laying asphalt, it’s essential to prepare the base. This step may involve excavation, grading, and adding a foundation layer like gravel or crushed stone. Base preparation can significantly impact the total cost, depending on the condition of the ground and the amount of work needed to create a stable foundation.

3. Obtain Contractor Quotes  

Once you have the measurements and an understanding of what base preparation is required, reach out to local contractors to get quotes. Many contractors will provide an estimate based on the size of the project, the thickness of the asphalt, and any additional requirements, such as drainage systems or edging. Request detailed quotes that include the cost of materials, labor, and equipment to avoid hidden charges.

4. Apply Pricing to the Area  

Asphalt pricing varies depending on your location, the quality of materials, and the contractor you choose. However, a general estimate for asphalt paving can range between $50 and $150 per square metre. To calculate the total asphalt cost, multiply the price per square metre by the area you’ve measured.

For example, if the contractor’s rate is $80 per square metre for a 100 square metre driveway, your total asphalt cost will be:

• 100 square metres × 80 dollars per square metre = 8,000 dollars

5. Account for Additional Costs  

Additional expenses, such as drainage installation, curbing, or edging, can add to the overall cost. Ensure your contractor includes these in the estimate, or ask for a separate breakdown of these items so you can budget accordingly.

Example Project Calculation: 100 Square Metre Driveway

To help you visualize how to estimate costs, let’s go through a practical example:

• Project: Paving a 100 square metre driveway.

Step 1: Measuring the Area  

The driveway is 10 metres long and 10 metres wide, giving you a total area of 100 square metres.

Step 2: Base Preparation  

The ground needs excavation and the addition of a gravel base. The contractor estimates the base preparation cost at $15 per square metre:

• 100square metres×15dollars per square metre=1,500dollars

Step 3: Asphalt Paving Cost  

The contractor quotes $80 per square metre for the asphalt installation, including labor and materials:

• 100square metres×80dollars per square metre=8,000dollars

Step 4: Additional Costs  

The project also requires drainage installation and edging, which the contractor estimates at $500 for drainage and $300 for edging.

Total Project Cost Breakdown:  

• Base preparation: $1,500  
• Asphalt installation: $8,000  
• Drainage: $500  
• Edging: $300  
• Total cost=1,500+8,000+500+300=10,300dollars

By following this example, you can adjust the numbers to fit your specific project size and requirements.

Estimating the total asphalt costs for your project doesn’t have to be complex. By carefully measuring the area, considering base preparation, and obtaining multiple quotes from reputable contractors, you can create an accurate estimate. Always account for additional costs like drainage or edging, which can significantly impact your final budget. This step-by-step approach ensures that you have a clear understanding of your project’s financial scope and helps prevent any unexpected expenses along the way.

The Environmental Impact Of Asphalt In NZ

Is Asphalt Eco-Friendly?

Asphalt is commonly used for road construction and infrastructure projects in New Zealand, but one of the key questions people often ask is: Is asphalt eco-friendly? The good news is that asphalt has a relatively low environmental impact compared to other traditional building materials. One of its standout features is its high recyclability, which plays a crucial role in reducing waste and conserving resources. 

In fact, asphalt is one of the most recycled materials globally. When roads are resurfaced, the old asphalt can be crushed, reprocessed, and used again in new projects without losing its structural integrity. This not only minimizes the need for new raw materials but also cuts down on the energy required for production, thus lowering overall greenhouse gas emissions. Moreover, asphalt’s long lifespan means it doesn’t need to be replaced as frequently as other materials, reducing the environmental burden associated with maintenance and replacement.

Additionally, the smooth surface of asphalt roads can contribute to better fuel efficiency for vehicles, which indirectly lowers carbon emissions. Less friction means vehicles consume less fuel, further decreasing their carbon footprint. For these reasons, asphalt can be considered an eco-friendly option when properly managed and utilized.

Sustainable Alternatives

As the demand for environmentally responsible construction practices grows, the industry has been innovating to meet these needs. In New Zealand, several sustainable alternatives to traditional asphalt are gaining traction. One notable development is the use of permeable asphalt, which is designed to help with drainage and reduce water runoff. 

Permeable asphalt allows water to pass through its surface, reducing the strain on stormwater systems and helping to mitigate flooding risks. This innovation is particularly beneficial in urban areas where natural drainage is often limited due to the prevalence of concrete and other impervious surfaces. By allowing water to filter through, permeable asphalt can also aid in replenishing groundwater supplies, which is essential for maintaining ecological balance.

Beyond permeable asphalt, there are other eco-friendly materials being introduced to the New Zealand market. These include warm-mix asphalt, which is produced at lower temperatures than traditional hot-mix asphalt, thus requiring less energy during manufacturing. Warm-mix asphalt not only reduces carbon emissions but also enhances worker safety by minimizing exposure to high temperatures.

Additionally, efforts are being made to incorporate more recycled materials into asphalt mixtures. Crushed glass, old tires, and plastic waste are being experimented with to create more sustainable asphalt products that retain the durability of conventional options while making use of materials that would otherwise end up in landfills.

While asphalt has traditionally been seen as a conventional material, its recyclability and innovations like permeable versions position it as a sustainable option in New Zealand’s construction industry. By choosing eco-friendly alternatives and recycling initiatives, we can continue to reduce the environmental impact of asphalt and move toward a more sustainable future for infrastructure development in NZ.

Maintaining Your Asphalt Surface For Longevity

Asphalt surfaces, such as driveways, parking lots, and roads, are durable and reliable, but like any surface, they require consistent care to maximize their lifespan. Proper maintenance not only helps preserve the appearance of your asphalt, but also prevents costly repairs or early replacement. By following a few essential steps, you can ensure that your asphalt surface remains in top condition for many years.

Regular Maintenance Tips

1. Cleaning: One of the simplest ways to maintain your asphalt is through regular cleaning. Dirt, debris, and leaves can accumulate on the surface and trap moisture, which can lead to erosion or damage. In particular, oil stains from vehicles are a concern as they can weaken the asphalt over time. Regularly sweeping and washing the surface helps keep it free of these contaminants, protecting the integrity of the asphalt.

2. Sealing: Sealing your asphalt is one of the most effective ways to protect it from the elements. Asphalt is constantly exposed to harsh weather conditions, including UV rays, rain, snow, and ice, all of which can break down the surface over time. Sealing creates a protective barrier that shields the asphalt from moisture penetration and prevents oxidation, which can cause cracking and brittleness. For optimal results, it’s recommended to seal your asphalt every 2-3 years, depending on the level of traffic it endures and the climate in your area.

3. Crack Filling: Cracks are inevitable in any asphalt surface, but addressing them early is crucial. Even small cracks can allow water to seep into the underlying layers, causing further damage and eventually leading to potholes. Filling cracks as soon as they appear helps prevent this from happening. Use a quality crack filler specifically designed for asphalt, and make sure the surface is clean and dry before applying it. Addressing cracks promptly ensures the longevity of your asphalt and minimizes the need for more extensive repairs later.

When to Consider Resurfacing vs. Repair

Over time, even the best-maintained asphalt surfaces will start to show signs of wear and tear. When this happens, property owners often face the decision of whether to repair the damaged areas or opt for resurfacing. Understanding the difference between the two and knowing when each is appropriate can save you time, money, and frustration.

1. Repairs: Small, localized issues, such as minor cracks or potholes, can often be fixed with simple repairs. This might involve filling cracks, patching potholes, or replacing a small section of the surface. Repairs are typically quick and cost-effective, especially if the rest of the surface is in good condition. However, if the damage is widespread, repairs may only be a temporary solution, as the underlying issues could continue to affect the asphalt.

2. Resurfacing: Resurfacing, also known as overlaying, involves applying a new top layer of asphalt over the existing surface. This method is more comprehensive than simple repairs and is ideal for surfaces that have moderate damage but are still structurally sound. Resurfacing can address issues like widespread cracking, surface erosion, and weathering while giving your asphalt a fresh, new look. It’s also more cost-effective than a full replacement, making it a popular choice when the damage is too extensive for patch repairs but the foundation of the asphalt is still solid.

When to Choose Resurfacing: If your asphalt surface is 15-20 years old, has widespread cracks, or the surface has become uneven due to weathering and traffic, resurfacing may be a better long-term solution. On the other hand, if the base of the asphalt has been compromised, such as in cases of large potholes, severe depressions, or crumbling edges, a full replacement may be necessary. Consulting with an asphalt professional will help you determine whether resurfacing is the best option for your specific situation.

Maintaining your asphalt surface requires regular cleaning, sealing, and timely repairs. When damage becomes too extensive for patchwork, resurfacing offers a cost-effective way to restore the surface and extend its life. By taking proactive steps and understanding when to repair versus resurface, you can ensure that your asphalt investment remains durable and visually appealing for years to come.
