Another FastPatch® HPRE-MD Installation on Maryland's Purple Line
FastPatch® HPRE-MD was again an essential part of a recent embedded track installation for Maryland Transit’s Purple Line. This time we were back for the second rail installation on the Sligo Creek Bridge, a key step in the Purple Line link between communities from New Carrollton to Bethesda.
HPRE-MD was the trusted rail grout solution for this application in cold weather on a sloped location, with quick installation & cure time.
- 1800 gallons of HPRE-MD with slope grade additive
- 10 hours total installation time, 2 days
- Set time 8 minutes
- Absorbs sound & vibration
- Provides electrical isolation
