Asphalt resurfacing is a process used to renew the surface of existing asphalt pavement, extending its lifespan and restoring its functionality and appearance. At Wright Construction Company, this method is commonly used when the underlying pavement structure is still sound but shows signs of wear and minor deterioration. Understanding the steps involved in asphalt resurfacing can help property owners like you make informed decisions about maintaining their asphalt surfaces effectively.
How Does Asphalt Resurfacing Work? 7 Steps to Resurface Asphalt
1. Initial Assessment & Preparation
The first step in asphalt resurfacing is conducting a thorough assessment of the existing pavement. When you work with Wright Construction, one of our asphalt resurfacing professionals will inspect your surface for cracks, potholes, uneven areas, and any underlying structural issues. This assessment helps determine whether resurfacing is appropriate or if more extensive repairs or even replacement are needed. Once the assessment is complete and the resurfacing process is agreed upon, the preparation phase begins. This typically involves cleaning the surface to remove debris, dirt, weeds, and any loose materials. Cleaning is essential to ensure proper adhesion of the new asphalt layer to the existing pavement.
2. Repairing Surface Imperfections
Before applying the new asphalt layer, surface imperfections such as cracks and potholes are repaired. Depending on the severity of the damage, cracks can be filled with a specialized crack filler or even sealed with hot, rubberized asphalt. Most of the time, our asphalt specialists repair potholes by cutting out the damaged area, cleaning the hole, applying a tack coat, and finally, filling it with hot mixed asphalt. Additionally, leveling and smoothing uneven areas is crucial during this phase. Low spots and depressions are leveled to ensure a smooth surface that promotes proper drainage and prevents water accumulation, which can lead to early onset deterioration of the asphalt.
3. Applying Tack Coat
After repairs are completed, a tack coat is applied to the entire surface of the existing asphalt pavement. The tack coat is a thin layer of asphalt emulsion or bonding agent that serves as a bond between the old and new asphalt layers. It promotes proper layer adhesion, improves waterproofing, and helps to prevent slipping between the layers during this process. The application of tack coat is critical for ensuring the longevity and performance of the resurfaced pavement. At Wright Construction, we evenly apply the tack coat using a distributor truck, ensuring complete coverage over the entire surface area.
4. Installing the New Asphalt Layer
With the tack coat in place, the new asphalt layer is installed using a paving machine. The paving process begins with the delivery of hot mix asphalt from an asphalt plant to the job site. In this form, the asphalt mix consists of aggregates such as gravel, sand, or crushed stone that are bound together by asphalt cement. The paving machine spreads and levels the hot mix asphalt to the desired thickness; we typically apply this mixture ranging from 1.5 to 2 inches for most of our resurfacing projects. The asphalt is then compacted using heavy rollers immediately after paving to reach a proper density and perfect smoothness. This proper compaction ensures durability, reduces the chances of future settlement, and improves the overall appearance of the pavement.
5. Final Quality Check & Finishing Touches
Once the new asphalt layer is compacted and cooled, a final quality check is conducted by a resurfacing specialist to inspect the smoothness, thickness, and overall integrity of the pavement project. Any necessary adjustments or finishing touches, such as trimming edges or cleaning the work area, are completed during this phase.
6. Curing & Opening to Traffic
After completion, the freshly resurfaced asphalt pavement requires time to cure and harden before opening to any traffic or vehicle weight. The curing process allows the asphalt binder to set and the pavement to achieve its maximum strength and durability. For commercial asphalt resurfacing projects, Wright Construction may resort to various traffic control measures, such as barricades or traffic cones. This can be used to restrict access to the newly resurfaced area during the curing period.
7. Regular Maintenance & Long-Term Care
Proper maintenance and routine care are essential for prolonging the lifespan of the resurfaced asphalt pavement. This includes regular inspections for cracks, potholes, and drainage issues, as well as timely repairs when needed. At Wright Construction, we offer these services as well as maintenance sealcoating to protect the surface from any oxidation or water invasion.
