However, the cost of installation can vary significantly depending on several variables, including the size of the area to be paved, the type of porous asphalt chosen, and the location of the project. Typically, the cost of a porous asphalt driveway ranges from $7 to $13 per square foot or around $2,800 to $5,200 for a standard-sized driveway.
Is Porous Pavement Expensive?
Porous asphalt, also known as permeable or porous pavement, is gaining popularity as a sustainable and eco-friendly paving option. It’s ability to allow water to seep through the surface and be absorbed by the ground beneath makes it an excellent solution for drainage issues. However, cost is often a major consideration when choosing any paving material, including porous asphalt.
The installation process itself can vary, depending on factors such as site preparation, grading, and the type of base material used. These factors can affect the overall cost per square foot.
On average, the cost of installing a porous asphalt driveway ranges from $7 to $13 per square foot. This cost includes labor, materials, and equipment required for the installation process. It’s important to note that this is just an estimate, and actual costs can vary depending on individual project specifications and location.
In comparison, pervious concrete, which offers similar benefits to porous asphalt, tends to have a slightly higher cost. The cost of installation for a pervious concrete driveway can range from $8 to $16 per square foot. Again, this estimate includes all necessary expenses related to the installation process.
It’s permeable nature helps reduce the need for traditional stormwater management systems, potentially saving on additional costs in the long run. Furthermore, the durability and low maintenance requirements of porous asphalt can also contribute to cost savings over time.
Before making a decision, it’s essential to discuss your specific project requirements with a professional contractor to get a more accurate cost estimate.

However, it’s important to consider the long-term cost savings and benefits of porous pavement. While the initial material cost may be higher, porous asphalt can result in reduced maintenance costs, improved stormwater management, and increased durability. In the long run, these advantages can outweigh the higher upfront expense and make porous pavement a cost-effective solution.
Is Porous Pavement More Expensive?
Porous asphalt, often known for it’s various environmental benefits, has become a popular choice in many paving projects. However, when it comes to cost, it’s essential to consider that porous asphalt is usually more expensive than traditional asphalt.
The sub-base preparation requires meticulous grading and compaction, while the specific void structure must be achieved to ensure proper water drainage. These additional steps contribute to the higher labor costs associated with porous pavement installation.
Maintenance of porous asphalt also needs to be taken into account. To retain it’s permeability and prevent clogging, periodic vacuuming or power washing may be necessary. Although this adds to the overall cost of porous pavement in the long run, it’s environmental benefits and extended lifespan often outweigh the maintenance expenses.
Reduced runoff and improved stormwater management can lead to potential savings in drainage infrastructure and water treatment expenses. Porous asphalts ability to naturally filter pollutants from water can also contribute to lower environmental remediation costs.
From stormwater management to environmental preservation, porous pavement offers several advantages that make it an attractive option despite the initial investment.

Pervious pavement and porous pavement are two distinct types of surfaces designed to promote water drainage. Pervious concrete is a specialized form of concrete, characterized by it’s high porosity, which enables water to flow through it, while porous asphalt is a variant of standard hot-mix asphalt that facilitates water drainage.
What Is the Difference Between Pervious Pavement and Porous Pavement?
Pervious pavement and porous pavement are two different types of surfaces that are designed to allow water to drain through them, reducing the strain on stormwater infrastructure and reducing the risk of flooding. While they serve a similar purpose, there are some key differences between the two.
Pervious concrete is a special type of concrete that’s designed with a high porosity, allowing water from precipitation and other sources to pass directly through it. This is achieved by using a carefully proportioned mixture of aggregate, cement, and water, along with the use of little to no sand during the mixing process. The result is a surface that resembles a sponge, allowing water to flow through it and into the ground below.
On the other hand, porous asphalt is a type of hot-mix asphalt that allows water to drain through it. It’s made from the same materials as traditional asphalt, but with the addition of larger aggregate particles and a smaller amount of the fine sand and filler materials typically used. This creates a pavement that’s interconnected voids, allowing water to pass through and infiltrate into the underlying soils. Porous asphalt is commonly used in parking lots, roadways, and other areas that experience high volumes of traffic.
A photo illustrating porous asphalt would show a surface that looks similar to traditional asphalt, but with a more open texture. The asphalt is typically darker in color, and the surface may appear slightly rougher due to the presence of the larger aggregate particles.
When considering the cost of porous asphalt per square foot, there are several factors to take into account. The cost will vary depending on the region, the size and complexity of the project, and the specific requirements of the site. Other factors that can affect the cost include the cost of materials, labor costs, and any additional site preparation or excavation that may be required. It’s best to consult with a professional contractor or pavement specialist to get an accurate estimate for a specific project.
Benefits and Drawbacks of Pervious Pavement and Porous Pavement
Pervious pavement and porous pavement are both types of surfaces that are designed to allow water to pass through them, rather than pooling on top or running off into storm drains. This can help to reduce the amount of stormwater runoff and minimize the strain on local drainage systems.
One of the main benefits of pervious and porous pavement is that they can help with stormwater management. By allowing water to infiltrate through the surface, they can help to replenish groundwater supplies and reduce the risk of flooding. They can also help to remove pollutants from the water as it passes through the pavement, improving overall water quality.
Another advantage of these types of surfaces is that they can help to mitigate heat island effects in urban areas. Pervious and porous pavements tend to absorb less heat than traditional asphalt or concrete surfaces, which can help to reduce the overall temperature of an area and improve comfort for pedestrians.
However, there are also some drawbacks to consider. One of the main challenges with pervious and porous pavements is that they can require more maintenance than traditional surfaces. Over time, the porous structure can become clogged with debris, which may need to be cleaned periodically to ensure proper drainage.
Additionally, these types of pavements typically have a higher upfront cost compared to traditional surfaces. The materials used and the installation process can be more complex, which can result in higher initial expenses. However, it’s important to consider the long-term benefits, such as reduced stormwater management costs and improved water quality.
In conclusion, pervious and porous pavements offer several benefits, including improved stormwater management and reduced heat island effects. However, they may require more maintenance and have a higher upfront cost. It’s important to weigh these factors when considering the use of these types of surfaces.
