Modular Grade Crossing Tubs Repair at Willow Springs Intermodal Yard in Chicago

Chicago polyurethane grouting

Willow Springs, Illinois

Crossing Repair in Chicago 2

The Job

This Chicago polyurethane grouting project is located at BNSF’s Willow Springs Intermodal yard, a critical facility in United States’ freight rail network. The facility is colocated with a large UPS trucking operation. BNSF has very tight time lines for transferring containers from inbound trains to UPS. There are dozens of crossings within the facility, which is primarily concrete pavement.

The Challenge

80 StarTrack modular grade crossing panels across 10 different crossings in the facility experienced settlement. The settlement was affecting the safe operation of yard trucks, causing delays in container transfer times.

Because of the 24/7/365 operation, and very tight performance times, there was no tolerance for downtime.

The Solution

CJGeo proposed grouting the affected panels with CJGrout-48NHL. 48NHL is best for differential settlement correction in high load applications, such as heavy haul rail. It cures within a few minutes, which allows immediate resumption of rail traffic and truck traffic.

CJGeo mobilized a polyurethane grouting crew with extensive modular grade crossing repair experience and grouted the 10 crossings over a period of five days onsite. This Chicago polyurethane grouting project did not affect rail traffic, yard truck operations, or performance metrics.
