One of the most cost efficient asphalt repair processes is one most laymen aren’t familiar with, and that’s asphalt milling. Here’s how asphalt milling and resurfacing services can revamp deteriorated pavement like parking lots or roadways.
The H&H Paving Guide to Asphalt Milling
What is Asphalt Milling?
This asphalt repair process involves grinding and removing the very top layer of asphalt pavement using specialized equipment made up of a pavement cutting drum, as well as a vacuum and conveyer belt to remove broken asphalt. Asphalt milling lets paving contractors repair any grading issues and lay down new asphalt on top of the exposed base layer for a fresh pavement surface.
The Asphalt Milling Process
- Every successful asphalt repair project begins with a thorough pavement inspection to determine the depth of asphalt to be removed and what areas need to be milled.
- Next, paving professionals employ asphalt milling machines. The milling drum rotates over the pavement, breaking up asphalt to the determined depth, then removing the broken asphalt to be recycled in other projects.
- Next, the exposed base layer is swept and cleaned to remove debris that could affect new asphalt bonding. The base layer can be repaired when necessary.
- Finally, new asphalt layers are installed to fill in to the depth of removed pavement and match the existing pavement level. Unlike asphalt repaving, existing structures like curbs and drainage systems aren’t affected by milling.
When Asphalt Milling Isn’t Enough
There are conditions when asphalt resurfacing won’t be able to fully repair pavement, including:
- Pavement that is over 20 years old
- Improperly installed asphalt
- Deep potholes or cracks that go all the way into the base layer
- The gravel base layer needs major repairs
