Engineers and construction experts are using new technology and materials to build bridges more quickly and efficiently while also enhancing maintenance for longer bridge life. Both new and old bridges are getting sensors installed to give constant feedback on their structural health. Engineers may better understand and solve issues by using this data, which also increases public safety. Utilizing ideas and designs from the past allows one bridge-building technology to create a new, structurally sound constructed bridge.
An inventive ᴍᴇᴛʜod for speeding up bridge building is the Geosynthetic Reinforced Soil-Integrated Bridge System, which combines an integrated approach, reinforced soil foundation, and the abutment. Granular soil is layered in layers that alternate with compacted granular fill, geosynthetic reinforcement, and geosynthetic reinforcement to form an effective composite material that is internally stable and capable of supporting bridge loads that are significantly higher than those intended while exhibiting predictable and dependable perforᴍᴀɴce. The new bridge is essentially a composite bridge structure that uses prefabricated superstructure components and GRS abutments. This ᴍᴇᴛʜod gets rid of the expensive downtime caused by cast-in-place concrete, which can take several weeks to cure.
Without seams, deep foundations, approach slabs, or cast-in-place concrete, the bridge is erected directly on the substructure, resulting in a seamless and smooth transition between the bridge and approach roads. Due to the simplicity of construction and the use of easily accessible materials and equipment, GRS-IBS projects can be erected in weeks as opposed to months. By providing affordable, sturdy, and long-lasting structures in a shorter amount of time during construction, GRS-IBS can assist states and local governmental agencies in meeting the nation’s deᴍᴀɴd for compact, single-span bridges.
Since the abutment’s construction is contained inside GRS-IBS’ footprint and a deep foundation is not required, it offers environmental benefits. Reduced building time and the necessity of using less steel and concrete significantly lessen environmental impacts. In addition to being strong and simple to maintain, these bridges are built with fewer components than those used in conventional construction. The ᴍᴇᴛʜod can be applied in less-than-ideal weather and can be modified on-site to account for unforeseen site conditions. Additionally effective and adaptable to a variety of loading circumstances are GRS-IBS bridges.
