The Job
Eight panels of StarTrack modular grade crossing tubs settled. As a result of the settlement multiple clips broke.
The Challenge
The crossing tubs settled, and when crossed by trucks, pumped water containing the subballast up between the tubs and adjacent pavement. The crossing was the only entrance into an industrial facility that took two trains per day. Because of limited onsite storage, rail service couldn’t be disrupted at all.
The Solution
CJGeo proposed grouting immediately below the panels, and also into the underlying disturbed subballast using CJGrout 48NHL geotechnical polyurethane grout. CJGeo performed the grouting without impacting rail traffic, and the facility was able to function normally throughout the repair, which took less than a day.
