Frequently Asked Questions
What is resurfacing?
Asphalt resurfacing is a process used to renew or repair existing asphalt pavement surfaces, such as roads, parking lots, driveways, and walkways. It involves applying a new layer of asphalt material over the top of an existing asphalt surface. This process is also sometimes referred to as “asphalt overlay” or “asphalt pavement resurfacing.” Here are the key steps involved in asphalt resurfacing:
1. Assessment and Preparation: The first step is to assess the condition of the existing asphalt pavement. Any existing cracks, potholes, or other damage must be repaired before resurfacing can proceed. This often involves filling cracks, patching holes, and addressing any structural issues.
2. Cleaning: The old asphalt surface is thoroughly cleaned to remove dirt, debris, and loose materials. This ensures proper adhesion of the new asphalt layer to the existing surface.
3. Tack Coat Application: A thin layer of tack coat, typically made of an asphalt emulsion, is applied to the cleaned surface. The tack coat acts as an adhesive, helping the new asphalt layer bond securely to the existing pavement.
4. Asphalt Application: A new layer of hot mix asphalt (HMA) is applied over the existing pavement. The thickness of the new layer can vary depending on the specific project requirements and the condition of the existing surface. Generally, it ranges from 1.5 to 2.5 inches (3.8 to 6.4 centimeters).
5. Compaction: Specialized heavy equipment, such as rollers, is used to compact and smooth the newly applied asphalt. Proper compaction is essential to ensure a level and durable surface.
6. Finishing: After compaction, the surface is often finished with a final layer of asphalt known as a “wearing course” or “surface course.” This layer provides a smooth, skid-resistant surface and enhances the appearance of the pavement.
7. Striping and Markings: If the resurfaced area is a roadway or parking lot, road striping and pavement markings may be applied to designate lanes, parking spaces, crosswalks, and other necessary features.
My asphalt is cracking can this be repaired?
Yes, cracks in asphalt pavement can typically be repaired. The specific repair method used depends on the type and extent of the cracks. Here are some common methods for repairing asphalt cracks:
1. Crack Sealing:
For small to moderate-sized cracks (typically less than 1/2 inch wide), crack sealing is a common and effective method. It involves filling the cracks with a specialized crack sealant or filler. The sealant is applied to the crack, and once it dries, it forms a flexible, waterproof seal that helps prevent water infiltration and further damage. Crack sealing is particularly effective for preventing the cracks from spreading.2. Crack Filling:
- Crack filling
Crack filling is similar to crack sealing but is often used for narrower cracks. A rubberized asphalt or polymer-based filler is applied into the crack to seal it and prevent water penetration. Crack filling is suitable for cracks that are not actively moving or widening.2. Patching:
For larger cracks or holes in the asphalt, patching may be necessary. This involves removing the damaged asphalt and replacing it with fresh asphalt material. The new asphalt is compacted and leveled to create a smooth surface.3. Infrared Asphalt Repair:
Infrared asphalt repair is a technique used for repairing larger areas of damaged asphalt, including extensive cracking. In this method, infrared heaters are used to heat the damaged area, making it workable. Then, new asphalt is mixed in and blended with the old asphalt to create a seamless repair. It’s a more advanced and long-lasting repair option.4. Resurfacing:
In cases where the asphalt has extensive cracking and deterioration, as discussed in a previous response, asphalt resurfacing or overlaying may be the best solution. This involves applying a new layer of asphalt over the existing pavement, effectively covering and sealing the existing cracks.
The choice of repair method depends on factors such as the severity of the cracks, the extent of the damage, and the overall condition of the pavement. It’s essential to assess the specific needs of your asphalt surface and consult with a professional asphalt contractor to determine the most suitable repair approach. Timely crack repair can help extend the life of your asphalt surface and prevent more extensive and costly damage in the future.
What are the benefits of asphalt?
Asphalt, often used in road construction and other paving applications, offers several benefits, making it a popular choice for various infrastructure projects. Some of the key advantages of using asphalt include:
1. Durability: Asphalt is a durable material that can withstand heavy traffic loads and adverse weather conditions. When properly maintained, asphalt surfaces can have a long service life.
2. Smooth Surface: Asphalt provides a smooth, even surface for vehicles to drive on. This smoothness can contribute to a more comfortable and safer driving experience.
3. Quick Construction and Repairs: Asphalt can be laid relatively quickly compared to other paving materials, reducing construction time and minimizing disruptions to traffic. Additionally, asphalt repairs, such as patching and resurfacing, are often faster and more cost-effective than concrete repairs.
4. Cost-Effective: Asphalt is generally more cost-effective to install and maintain than some other pavement materials. It can offer a lower initial construction cost, and routine maintenance, such as crack sealing and resurfacing, can be less expensive than extensive repairs or replacements.
5. Recyclability: Asphalt is a highly recyclable material. Old asphalt pavement can be reclaimed and reused in new asphalt mixtures, reducing the demand for new raw materials and conserving resources.
6. Skid Resistance: Asphalt surfaces can be engineered to provide good skid resistance, which is essential for safe driving, particularly in wet or icy conditions.
7. Noise Reduction: Asphalt surfaces can help reduce road noise, making them a suitable choice for urban areas where noise pollution is a concern. Various asphalt mix designs can be used to achieve specific noise-reduction goals.
8. Versatility: Asphalt can be used for a wide range of applications, including roads, highways, parking lots, driveways, airport runways, and more. It can be customized to meet the specific needs of various projects.
9. Low Maintenance: Asphalt requires less maintenance than some other materials. Routine maintenance tasks like crack sealing and periodic resurfacing can extend the life of the pavement.
10. Sustainability: Asphalt’s recyclability, energy efficiency in production, and potential for use in cool pavement technologies contribute to its sustainability profile. Efforts are continually being made to improve the environmental aspects of asphalt production and construction.
11. Energy Efficiency: Asphalt production is energy-efficient, which can help reduce greenhouse gas emissions associated with construction materials.
It’s worth noting that the performance and longevity of asphalt pavement depend on factors such as the quality of materials, proper construction techniques, and regular maintenance. To maximize the benefits of asphalt, it’s important to follow best practices in design, construction, and maintenance.
