Tub Crossing Repair

Vineland & Millville, NJ

The Job

The sandy soils of South Jersey are great for growing produce and mining pure silica sand. While most of the produce is shipped by truck, a lot of the silica is shipped by rail. The rails inevitably cross the roads, and many of the crossings are at grade.

The Challenge

A short-line railroad was experiencing significant settlement and pumping of multiple precast modular crossings in the Vineland & Millville areas. Each crossing saw significant truck traffic, primarily from aggregate mining, and also significant heavy haul rail traffic from transporting sand.

The Solution

Working with a rail maintenance contractor, CJGeo performed polyurethane grouting on a total of four precast tub crossings in the area. Each was done in a single day, with the immediate resumption of automobile traffic, and rail traffic. Supplemental bolting was performed to address the deterioration of the panels that had resulted from the extensive movement of the panels.
