There’s nothing new about asphalt paving. The surfacing technology has a long history, and asphalt continues to be a widely used paving material across the country.
Over the years, asphalt companies have found ways to make the paving process more efficient and to enhance the quality of the product. For instance, there’s now a greater emphasis on reclamation and recycling.
In today’s blog, we talk about three of the latest asphalt processes that keep paving costs low while making the final product sturdier than before.
There are two kinds of asphalt damage, one that permeates the surface and one that deteriorates the base or sub-base. If the damage is restricted to the surface while the foundation is still intact, you can go for asphalt milling.
Milling involves removing the top layer of the pavement, crushing it, and mixing it with new cement to repave the surface. As a result, you will have a fresh-looking road or parking lot without disturbing the sub-base.
Benefits of milling include:
- Save time and money on a repaving project.
- Keeps sub-base intact
Milling is ideal if the pavement becomes elevated and you need to remove a couple of inches off the top.
Like milling, this process also involves pulling out and crushing existing asphalt using specialized machinery. Pulverization is the first step in the repaving process, one that’s necessary to ground existing asphalt that can be stabilized into a solid surface.
Benefits of pulverizing include:
- Makes extremely durable surfaces
- Pulverized surfaces require only a little maintenance.
Pulverization is ideal when you need to rehabilitate a road with minimal traffic disruption without bearing the full cost of asphalt replacement.
Once the existing surface is pulverized, you are left with the ground-up pavement. The crushed asphalt is overlaid with tar and other waterproofing and binding agents and mixed thoroughly.
The mixture is left to harden, at least for 24 hours. Once hardened, the material is ready for re-use to pave a road or driveway, which will be as strong and durable as the initially paved surface.
Benefits of stabilization include:
- Replacing broken or elevated asphalt with minimal costs and traffic disruption
- Recycling asphalt conserves the environment.
- The stabilized asphalt is as durable as new cement.
As you can see, the latest asphalt processes are focused on making the paving process more efficient and reduce traffic disruption on commercial/municipal properties. And these processes help asphalt paving contractors and property owners reduce their carbon footprint.
