Whether you’re a property owner, manager, or simply interested in understanding the nuances of pavement care, this guide serves as your comprehensive resource for navigating the world of asphalt resurfacing.
What is Asphalt Resurfacing?
Asphalt resurfacing extends beyond mere surface restoration. It plays a vital role in extending the lifespan of pavement infrastructure while simultaneously enhancing safety and visual appeal.
Asphalt resurfacing is a maintenance procedure that replaces worn-out asphalt surfaces, commonly employed for roads, parking lots, asphalt driveways, and other paved areas. Unlike complete pavement reconstruction, which involves removing the existing pavement entirely and laying down a new base layer along with fresh asphalt, resurfacing requires only applying a new layer of asphalt.
This approach offers several advantages, including cost-effectiveness and reduced disruption to traffic, depending on the type of project. By simply covering the existing asphalt with a new layer, resurfacing can effectively address both minor and major surface imperfections, cracks, and deterioration in asphalt pavements, restoring the pavement’s functionality and appearance.
One of the key distinctions between asphalt resurfacing and complete pavement reconstruction lies in the extent of the work involved and the associated costs. While resurfacing offers a relatively less intrusive and more economical solution for restoring pavement integrity, complete reconstruction only becomes necessary when the underlying base layers are severely compromised or when significant structural defects are present.
Resurfacing is often preferred over simple repairs or patching when the surface damage is widespread or when the existing pavement exhibits signs of aging, such as widespread cracking or surface deterioration. Additionally, resurfacing allows for the preservation of the existing pavement structure and base layers, minimizing the environmental impact associated with complete reconstruction.
Key Benefits of Asphalt Resurfacing
As mentioned, there are several benefits to asphalt resurfacing including safety, aesthetics, and improved lifespan.

This proactive approach to maintenance reduces long-term maintenance expenses, ensuring the longevity and functionality of the paved surface for years.
How Often Should Asphalt Be Resurfaced?
Determining the optimal timing for asphalt resurfacing is essential for maintaining pavement integrity and maximizing its lifespan. While the frequency of resurfacing can vary depending on factors such as traffic volume, climate conditions, and pavement quality, there are several key indicators to watch for that signal the need for resurfacing. Driveway resurfacing is a critical maintenance action for homeowners to consider, especially when these signs of wear and deterioration become apparent.
One sign that asphalt may require resurfacing is the presence of extensive cracking, particularly if cracks are widespread and penetrate through the surface layer. Cracks not only detract from the pavement’s appearance but also serve as entry points for water and other harmful substances, leading to accelerated deterioration of the underlying pavement layers. Additionally, the formation of potholes, depressions, or rutting indicates significant pavement distress and may necessitate resurfacing to restore a smooth, level surface and prevent further structural damage.
Furthermore, faded or worn pavement markings and striping can compromise traffic safety and efficiency, signaling the need for resurfacing to ensure clear delineation of lanes, crosswalks, and other traffic control devices. Additionally, areas of severe surface deterioration, such as raveling or aggregate loss, may require prompt attention to prevent further degradation and maintain pavement functionality.
Regular inspections and proactive maintenance efforts can help identify the need for resurfacing and prevent minor issues from escalating into more significant and costly repairs. By staying alert and responsive to pavement condition indicators, property owners and managers can effectively manage their asphalt assets and ensure safe, functional, and aesthetically pleasing paved surfaces for years to come.
The Asphalt Resurfacing Process Explained
The driveway resurfacing process is a systematic procedure aimed at rejuvenating worn-out pavement surfaces, ensuring their functionality and longevity. Here’s a step-by-step breakdown of the driveway resurfacing process, from initial assessment to completion:
Initial Damage Assessment
The process begins with a comprehensive assessment of the existing pavement to identify any surface defects, cracks, or deterioration. This step helps determine the extent of work required and allows for proper planning and preparation.
Surface Preparation
Before resurfacing can commence, the pavement surface is cleaned thoroughly to remove dirt, debris, and vegetation. You want to have as little dirt and leaves on the surface as possible to minimize damage and ensure you're not sealing dirt and other debris in the new asphalt driveway or surface. This can be done quickly by power washing the old pavement.
Crack and Damage Repair
Before laying new asphalt during the resurfacing process, it's imperative to address existing cracks and structural issues in the pavement. Crack and damage repair play a pivotal role in ensuring the longevity and performance of the newly applied asphalt overlay.
First and foremost, repairing cracks helps prevent moisture infiltration into the underlying layers of the pavement. Water seeping into cracks can lead to the deterioration of the pavement's base layers, weakening its structural integrity over time. By repairing cracks before resurfacing, property owners can mitigate the risk of further damage and extend the lifespan of the pavement. To repair cracks, it's best to clear them of any debris so that you can fill them fully with fresh asphalt. Again, you can use a power washer to get that debris out of the cracks.
Additionally, addressing structural issues such as potholes, depressions, and rutting is essential for achieving a smooth and uniform pavement surface. Potholes and depressions not only detract from the aesthetics of the pavement but also pose safety hazards to vehicles and pedestrians. Repairing these structural defects before laying new asphalt ensures a level surface and improves the overall functionality and safety of the pavement.
Applying the New Asphalt Layer
Once the pavement has been prepared, the next step involves applying a new layer of asphalt over the existing surface. This overlay, typically between 1.5 to 3 inches thick, is applied using specialized paving equipment. The asphalt resurfacing material, also called asphalt millings, is then carefully spread and compacted to achieve the desired thickness and smoothness, ensuring proper adhesion to the existing pavement surface.
Compacting the New Asphalt Surface
After the overlay has been applied, it is compacted using rolling and paving machines like tandem rollers such as rollers to ensure proper compaction and eliminate any air voids. Compaction is critical for achieving a durable, long-lasting pavement surface that can withstand traffic loads and environmental conditions. Multiple passes may be required to achieve the desired level of compaction and smoothness.
Curing and Sealcoating
Once the overlay has been compacted, any necessary finishing touches are applied. This may include installing pavement markings, striping, or other traffic control devices to ensure safe and efficient traffic flow. Additionally, any landscaping or roadside features that were temporarily removed during the resurfacing process may be restored to their original condition.
Finally, the newly resurfaced driveway and surface need time to cure and harden before it can be opened to traffic. Curing times can vary depending on factors such as temperature and humidity but typically range from a few hours to a few days. During this time, traffic may be diverted or restricted to allow for proper curing and to prevent damage to the freshly laid asphalt.
Sealcoating is a protective coating applied to asphalt surfaces after they have been initially installed or resurfaced. While sealcoating is not typically part of the asphalt resurfacing process itself, it is often recommended as a supplementary maintenance measure to prolong the lifespan of the pavement and enhance its durability.
Ideally, sealcoating is applied to asphalt surfaces every few years, depending on factors such as climate conditions, traffic volume, and pavement age. Sealcoating serves as a barrier against harmful elements such as UV rays, water, oil, and gasoline, helping to prevent premature deterioration and extending the life of the asphalt pavement. While it can be applied at any time during the pavement's lifespan, sealcoating is often recommended shortly after the asphalt has fully cured or after resurfacing to maximize its effectiveness.
How Much Does Asphalt Resurfacing Cost?
The cost of asphalt resurfacing can vary widely depending on several factors, including the size and condition of the pavement area, local labor and material costs, and any additional services required. However, to provide a general idea for budgeting purposes, it's helpful to consider some average cost estimates for resurfacing projects.
On average, asphalt resurfacing costs between $3 to $7 per square foot. This cost typically includes labor, materials, equipment rental, and any necessary preparation and cleanup. For example, resurfacing a standard two-car driveway measuring 18 feet wide and 40 feet long (720 square feet) could cost anywhere from $2,160 to $5,040.
Keep in mind that certain factors can impact the overall cost of an asphalt resurfacing project. For instance, if extensive repairs or preparatory work, such as crack sealing or patching, are required before resurfacing can begin, this can add to the total cost. Similarly, factors such as accessibility, site conditions, and the complexity of the project can influence pricing. It's also worth noting that economies of scale may apply to larger resurfacing projects, resulting in lower costs per square foot compared to smaller projects.
Ultimately, the best way to obtain an accurate cost estimate for an asphalt resurfacing project is to consult with local paving contractors or professionals who can assess the specific requirements of the project and provide tailored pricing based on factors such as pavement condition, size, and location.
