Find Rip Rap Under 03

Rip rap is used where water and erosion meet railroad construction. ARM products ending in 03 are also called Sand & Gravel and can be used as rip rap.

How the 03 Rule Works

Look for the two-digit 03 ending. Those products live in Sand & Gravel even when the modeling job is rip rap.

Product number ends in 03

Use 03 material for culvert mouths, drainage channels, bridge approaches, shorelines, creek banks, and protected embankments.
