When surfaces are too damaged to fill, seal coat, patch or make other spot asphalt repairs, the asphalt pulverizing process offers an economical way to fully rehabilitate a road with little disruption to traffic. Rock Solid’s pavement grinding services extend the lifespan of the existing road and base and enable grading of the revitalized base to repair slope issues. We also make projects more sustainable by salvaging all of the existing aggregate base and asphalt base & surface materials for re-use. As a leading national soil stabilization company, we’re your top choice for asphalt pulverization services.
Eliminates reflective cracking and extends existing road life without complete removal and replacement
Existing aggregate base and asphalt materials can be salvaged for re-use in the project
Allows for re-grading to re-profile slope deficiencies
- Asphalt can be replaced quickly with a minimum of cost, effort, and traffic disruption
- Eliminates removal costs when not restricted by grade or elevation project limitations
- Can be utilized on existing chip seal and HMA pavements up to 15+” thick
Roads, parking lots and other surfaces see a lot of wear and keeping them maintained can put a strain on a budget. Asphalt pulverization is a method of pavement rehabilitation that consists of pulverizing and grinding together the distressed layer of existing asphalt pavement along with a portion of the underlying base, grading and compacting the resulting mixture, creating a revitalized aggregate road base. This revitalized road base can support a protective surface of hot mix asphalt (HMA), micro-surface, or chip seal.
For clients facing significant pavement damage, asphalt pulverization offers a comprehensive and cost-effective solution. It reduces the need for costly new materials and extensive labor. This approach not only extends the lifespan of the pavement but also maximizes budget efficiency.
The result is a rebuilt road, using a minimum of new asphalt, that is as strong and reliable as the original construction. And no pavement has to be hauled away, which saves money on trucking and excavating.
A Crucial Step for Rebuilding
Pavement grinding is an essential step for rebuilding a road, parking lot or other surface. When undertaking a full-depth reclamation (FDR) project, asphalt grinding is the first step in performing mechanical or chemical FDR. Here’s a brief overview of how the road grinding process works:
- Asphalt pavement is pulverized in place along with the underlying base. A stabilizing additive is mixed in during chemical FDR. This procedure allows the materials to be re-used so that they don’t go to waste, while also eliminating soft spots.
- The resulting mixture of pulverized asphalt and base are graded and compacted. The grading process ensures the finished product is to grade, while compacting enhances its overall strength.
- Final grading and rolling creates a smooth, stable surface for the application of a wearing course for added protection and stability.
Pulverization and Your Project
Pulverization can benefit a wide range of groups or individuals who are undertaking stabilization or reclamation projects, including contractors, property owners, developers and government entities. For example, the owners of a shopping mall may need to repair a parking lot that is deteriorating. Townships and municipalities often have to replace roads spotted with potholes. Our asphalt grinding services can help make these jobs easier, less wasteful and more successful in the long run.
Why Choose Rock Solid?
Our expert pavement grinding contractors offer customers across the country the opportunity to realize the many benefits of pulverization. With our help, your project can use fewer new materials, experience lower haul-away costs, recycle materials on-site and finish the work faster than with other methods.
The strength and longevity of the newly pulverized base ensure that your rehabilitated pavement will stand the test of time, providing a durable and stable foundation for years to come. Our expertise in asphalt pulverization means that you will achieve a high-quality, long-lasting result that maximizes your investment.
Frequently Asked Questions
Unlike milling, which only removes the top layer of paving, asphalt pulverization grinds the existing asphalt and blends the fine particles with the underlying base. This creates a stronger foundation and eliminates the need for hauling away the old materials.
Because existing materials are recycled on-site, pulverizing asphalt paving saves time and money that would have been spent on hauling away asphalt and disposing of it. This minimizes project downtime while also improving the sustainability of the project.
Typically, pulverization is not recommended in cases where the subgrade is unstable, if there are severe drainage issues or the sub-base requires reconstruction. These are situations in which other methods may be a better choice.
The asphalt is ground to a set depth, and the resulting materials are blended with the base. This is then graded and compacted to form a newly stabilized surface. In general, pulverization is faster than full replacement because there’s no need for hauling away and disposing of the old asphalt.
If done properly, pulverized and stabilized asphalt will perform as well or better than a full removal and replacement. Stabilizers such as cement or asphalt emulsion can ensure even better results that last longer and perform better.
