Lateral loads on bridges can result from earth pressure, seismic forces, wind loads, traffic or even ship impact or wave action. In cases where lateral loads govern, it is not uncommon to see designers add additional piles or drilled shafts or increasing the size of pile or shaft caps. This document by the Transportation Research Board provides recommendations for ground improvement methods for improving lateral resistance of weak soils, including a simplified approach for assessing the lateral resistance of improved soils using commercially available software packages.

Hayward Baker Breaks Ground on Recently Awarded K-10 South Lawrence Trafficway Ground Improvement Project in Lawrence, Kansas
Hayward Baker (HB) recently began work on a $9.1 million ground improvement contract for the K-10 South Lawrence Trafficway (SLT) Project located in Lawrence, Kan. as a subcontractor to Emery Sapp & Sons, Inc. The project provides a significantly improved transportation infrastructure for the state, making it a top priority for the Kansas Department of Transportation (KDOT).
Current construction will complete the southern K-10 bypass from its intersection with US 59 to the existing K-10 east of Lawrence. Construction affects 58 acres of wetlands. However, mitigation agreements between KDOT, local government agencies, and the public will create and restore 317 acres of wetlands as well as restore, preserve, and create over 50 acres of habitats.

[Editor] An effluent pond in southeast Texas was suffering from years of erosion. Recently, an escalation of subsurface water seepage through the pond’s embankment threatened the community’s main water source. URETEK used their versatile geopolymer product to inject beneath the embankment to seal off the seepage. The project was a huge success!
