Notes
The City of College Station needed to widen Rock Prairie Road from two lanes to four, incorporating bike lanes and sidewalks. The project faced significant challenges due to saturated high plasticity (PI) clay subgrades, which weakened under moisture and rendered traditional excavation and soil replacement methods costly and ineffective. A trial section using TerraGrid TXG-7 demonstrated remarkable performance, outperforming traditional chemical stabilization methods. The geogrid allowed for the completion of the roadway within budget and on time, while delivering a durable, long-lasting pavement structure.
