The Difference Between Asphalt Milling, Pulverizing & Stabilization

Asphalt is something that’s not a new addition to our society. In fact, asphalt has existed for much longer than many people realize. After the years of use and production, new technologies to perfect the asphalting process have been created. Today we’re going to take a closer look at three of the most important processes used with asphalt in our modern world.


Asphalt milling is designed to recycle and re-use asphalt. To do this, only the top layer of asphalt is removed while the sub-base is left intact. This top layer is removed by a machine called a cold planer. The cold planer goes over the asphalt with spikes, pulling up the top layer. As that top layer is removed, it’s stored to be taken back to the manufacturing area and be mixed in with new asphalt. Finally, a new layer of asphalt is placed over the existing sub-base. Milling is a process that saves time and money while decreases the negative impact on the environment through the recycling process.


Pulverizing is often confused with milling, but the two are very different. Pulverizing also involves ripping up the top layers of asphalt, but instead of removing the old asphalt during the process, it is left behind. The crumbled asphalt is then used in the next process we’ll talk about, stabilization.


Stabilization is the next step after pulverizing asphalt is complete. In this step, the crumbled remains of asphalt left behind are transformed into new asphalt. This is done with a mixture of tar and binding agents that are poured over the old asphalt. This new mixture needs 24-48 hours to harden into reliable asphalt once again. After the hardening is complete, the result is just as stable as new asphalt would be. Stabilization is a process that is low cost and causes minimum interruption to the flow of traffic, unlike traditional asphalt practices.

All of these processes focus on reusing the materials that already exist in the asphalt. This new mindset of recycling and reusing is extremely beneficial to our environment in the long term, as well as the pocketbooks of taxpayers and city planners. We expect to see these methods continue to be revolutionized in the years to come, making them, even more, cost-effective and environmentally friendly!
