TXDOT Highway Rehabilitation and Leveling

Problem

• Extensive repairs were needed in Houston’s NE quadrant where I-10, the 610 Loop, I-59 and I-69 feed into Harris County
• The issues were potholes, settled roadway and bridge approach slabs, dips, caused by a variety of problems such as soil subsidence, vibration, washout, poor base soils, necessitating highway rehabilitation and leveling

Solution

• Foamjack with TerraThane™ geotechnical polyurethane to void fill, stabilize, lift and realign the slabs
• Create smooth driving paths by identifying key problem areas and designing an injection plan to meet goals, whether void-filling or concrete lifting
• Minimize disruption to highway system by working during non-peak hours

Results

• Over half a million pounds of TerraThane 24-003 Polymer was injected in over 150 locations
• Minimal impact was made to traffic as work was performed during the evening hours
• Because of the fast-curing polymer, the work area was continuously advancing, because traffic could utilize the roadway within minutes of installation
