Utility Trenching Blades: Fast Cuts in Asphalt and Sub-Base Aggregates
Direct Answer: Utility trenching through road asphalt and sub-base concrete requires hard-bond diamond trenching blades featuring undercut-protected drop segments and tungsten carbide pin inserts. Because utility trenching cuts through mixed layers of asphalt overlay, crushed rock, and concrete sub-base, hard bonds prevent sand slurry from stripping segments.

Frequently Asked Questions
Why do utility trenching blades fail quickly on mixed asphalt/concrete?
Asphalt sand slurry undercuts standard blades. Dual-purpose blades with drop segments shield the core weld line from abrasive slurry wash.
