The Job
This tub crossing repairs project is located in Charlotte, North Carolina. Fifty two OldCastle StarTrack panels at four different grade crossings settled to the point of requiring slow orders at the crossings. In order to restore the track to normal speeds, the settlement had to be corrected.
The Challenge
Due to scheduling constraints with rail traffic, with very short windows on weekend nights, the owner elected to have the repairs completed during a single weekend shutdown period. While this allowed for longer work periods, it also meant that four crossings needed to be repaired in fewer than 24 hours.
The Solution
CJGeo mobilized two polyurethane grouting crews to the system, and grouted two crossings each during two shifts. All 52 of the panels were stabilized and lifted back to grade using CJGrout 48NHL, which allows for immediate resumption of rail traffic, from light rail to heavy haul.
Polyurethane grouting is also sometimes called structural polymer grouting. Regardless of name, the process works very well where fast return to service is important. In the case of tub crossing repairs, grout must set very quickly in order for rail traffic to resume. CJGrout 48NHL achieves 95% of its ultimate strength in fewer than 15 minutes.
