Construction and Monitoring of Alabama’s First Geosynthetic Reinforced Soil-Integrated Bridge System
Geosynthetic reinforced soil-integrated bridge systems (GRS-IBS) are increasingly being used for rapid, cost-effective construction of bridges. This system works by constructing a geosynthetic reinforced soil abutment on the native material and an integrated bridge approach which can reduce differential settlement between the abutment and approach road. Recently, the first GRS-IBS was constructed in the state of Alabama, located on Turkey Creek, in the Sand Mountain region of Marshall County. Two 3.6-m (11.72-ft) high GRS-IBS abutments were constructed on native Pottsville sandstone. The site was monitored during construction and continues to be surveyed to measure any movement of the abutments. The abutments were also instrumented with pore pressure transducers and earth pressure cells to monitor any change in in situ stresses. This paper provides an overview of the construction of the bridge and describes trends observed in the monitoring data. Lessons learned during the construction process and suggestions for future projects are discussed.
