Has anyone had any experience milling TLA? Is it any harder on teeth?
If it's natural asphalt it shouldn't be harder on your teeth unless they modified it with polymer.
If i'm reading correctly, it actually replaces a portion of the polymers in SMA.
The project we worked on was fully natural asphalt and everything went normally. If they used in as a modifier in PG binders it should mill normally, but the SMA's are a bit harder due to the stone structure, but not anything outside of normal.
