TXDOT Highway Rehabilitation and Leveling

Potholes, settled roadway and bridge approach slabs, dips, caused by a variety of problems such as soil subsidence, vibration, washout, poor base soils
About The Project
Contractor Nortex
Project Location Houston, TX
Product Used Terrathane™ 24-003

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

Solution

  • Foamjack with TerraThane™ geotechnical polyurethane to voidfill, 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
