Pulverizing
Pulverizing
Pulverizing is the process of completely grinding up all layers of asphalt and leaving the pulverized asphalt as a base course in preparation for a new layer of asphalt to be placed.
The pulverized asphalt is recycled right where its at. This eliminates the need to haul away any material which conserves fuel, while also strengthening the road base.
Pulverizing eliminates all reflective cracking in roads, it also allows a road to be completely re-shaped. This gives the opportunity to flatten out any bumps, hills, highspots, or any flaws that were in the old road or base.
Milling
Milling
Milling blacktop is the process of removing the of or surface layer of asphalt from an existing road in preparation for a new layer to be laid down. This is not complete reconstruction, traffic can still flow without significant delays or closing the road.
By removing the surface layer of asphalt, surface cracks, crack fillers, heaves, ruts, and potholes are completely removed with it. This enables the new layer of asphalt to ride smoother as old imperfections have been removed from the road.
Milling is an environmentally friendly way to recycle asphalt because the ground up asphalt is recycled in new asphalt.

Foamed Asphalt
Foamed Asphalt Stabilization
Foamed asphalt stabilization is the process of injecting hot, foamed asphalt into the base of a road with the use of a pulverizing machine.
Asphalt pavement is flexible and conforms to the shape of the base beneath it. A strong base is key in order to ensure long lasting pavement.
Foamed asphalt stabilizaton is essential in marshy or swampy areas that have weak or unstable bases. The use of this to make a stronger base allows for a thinner layer of asphalt to be placed ontop. Reducing costs while promoting a stronger, more durable road.
