Bridges often deteriorate with aging due to corrosion and require strengthening.\u00a0 In some parts of the world, seismic upgrade<\/strong><\/a>\u00a0of these structures is required for compliance with latest design codes.\u00a0 Many older bridges may require strengthening of the superstructure and substructure to increase their live load carrying capacity and rating.\u00a0 All these conditions create an ideal environment for repair and strengthening of bridges and transportation infrastructure with Afzir Fiber Reinforced Polymer (FRP) products.<\/p>\n Advances in FRP composites have led to structural systems that allow for rapid deployment of bridge decks and other highway structures. The bridge structures under discussion include FRP bridge deck, stringer<\/strong><\/a>, beam, abutment panel, rebar, dowel bar and posts. Other FRP highway structures are signpost, signboard, guardrail system, sound barrier, drainage system (pipe, culvert), etc. Each of these products represents a high-volume market.<\/p>\n Our engineered FRP solutions offer fast, long-lasting and economical repair alternatives to owners, architect\/engineers and contractors involved with the transportation industry to ensure the project is completed on time, within budget and with minimum disruption of service.\u00a0 These systems are particularly ideal when the repairs have to be completed in a short time frame and provide a long service life.\u00a0 Afzir FRP systems have been extensively tested by several state departments of transportation and their effectiveness has been well documented.<\/p>\n Some of the repair and strengthening projects in bridge and transportation industry that can benefit from Afzir\u00ae engineered FRP solutions are:<\/p>\n In most cases, Afzir engineers can provide a complete \u201cturnkey\u201d design-build solution that includes sealed engineering drawings by our in-house engineers, all of the materials needed, and installation by one of our approved and certified installers or our construction company.\u00a0 This unique turnkey design-build approach results in significant efficiency, time and cost-savings, and minimizes the potential errors and delays that can result when multiple groups are involved in one project.<\/p>\n Afzir also welcomes the opportunity to partner with owners, architects, engineers and contractors by providing any single aspect of the project, i.e., design, materials, or installation for a specific project in any bridge project.<\/p>\n<\/div>\n Airports whether large or small have a variety of structures that require maintenance and strengthening.\u00a0 Many of these facilities were constructed decades ago and have reached or exceeded their original service life. \u00a0Afzir\u2019s Fiber Reinforced Polymer (<\/span>FRP) products can offer an economical solution to many such repair projects.\u00a0 These repairs can be performed in much shorter time compared to conventional repairs using steel and concrete.\u00a0 Our engineered FRP solutions ensure the project is completed on time, within budget and with minimum disruption of service to the traveling public.<\/span><\/p>\n Some of the repair and strengthening projects in airports that can benefit from Afzir engineered FRP solutions are:<\/p>\n In most cases, Afzir engineers can provide a complete \u201cturnkey\u201d design-build solution that includes sealed engineering drawings by our in-house engineers, all of the materials needed, and installation by one of our approved and certified installers or our construction company.\u00a0 This unique turnkey design-build approach results in significant efficiency, time and cost-savings, and minimizes the potential errors and delays that can result when multiple groups are involved in one project.<\/p>\n Afzir also welcomes the opportunity to partner with owners, architects, engineers and contractors by providing any single aspect of the project, i.e., design, materials, or installation for a specific project in any bridge project.<\/p>\n National and regional railroads throughout the world have a significant inventory of bridges. Many of these structures were constructed decades ago and have reached or exceeded their original service life. The remote location of these structures that is often hard to access make repairs with conventional materials such as concrete and steel very difficult and costly. Afzir\u2019s Fiber Reinforced Polymer (FRP<\/span>) products can offer an economical solution to many such repair projects.\u00a0 Whether it is for corrosion repair of concrete and steel beams and columns, strengthening of deteriorated timber beams and piles, increased live load capacity, or seismic upgrade, FRP offers fast, economical and long lasting solutions compared to conventional repairs with steel and concrete.<\/p>\n Our engineered FRP solutions ensure the project is completed on time, within budget and with minimum disruption of service.\u00a0 In some cases, we can train the railroad\u2019s maintenance crew so they can maintain their bridges when their workload is light to allow such tasks.\u00a0 Afzir FRP systems have been extensively tested by several state departments of transportation and their effectiveness on strengthening of piles and columns has been well documented.<\/p>\n Some of the repair and strengthening projects in railroad industry that can benefit from Afzir\u00ae engineered FRP solutions are:<\/p>\n In most cases, Afzir engineers can provide a complete \u201cturnkey\u201d design-build solution that includes sealed engineering drawings by our in-house engineers, all of the materials needed, and installation by one of our approved and certified installers or our construction company.\u00a0 This unique turnkey design-build approach results in significant efficiency, time and cost-savings, and minimizes the potential errors and delays that can result when multiple groups are involved in one project.<\/p>\n Afzir also welcomes the opportunity to partner with owners, architects, engineers and contractors by providing any single aspect of the project, i.e., design, materials, or installation for a specific project in any bridge project.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

The application of FRPs for civil infrastructure is resulting in a paradigm shift in material usage because FRPs provide favorable material properties (Figure 2). For example, FRPs provide nonmagnetic and noncorrosive products with higher strength to weight ratios than conventional materials. FRPs are also \u2018greener\u2019 in terms of embodied energy than concrete and steel. The use of FRP composites in civil infrastructure can improve innovation, increase productivity, enhance performance, and provide longer service lives, i.e. reduced life-cycle costs. Through proper selection of polymeric resin<\/strong><\/a> systems and reinforcements, FRPs can be tailor-made to meet certain strength and performance requirements.
\nPotential ease of application of FRP composites has led the academia and industry to focus their initial research and implementation in: 1) corrosion resistant reinforcing bars (rebar) for highways; 2) bridge decks and superstructures; 3) hazardous material containers susceptible to chemicals; 4) structures with longer spans (> 10,000 feet span) resulting in reduced self weight; 5) utility poles and towers; 6) strengthening and wrapping of\u00a0in-service structures; and 7) many others, including cold water pipe for Ocean Thermal Energy Conversion project and composite deck houses for next generation navy battle ships.<\/p>\n![\"\"](\"https:\/\/afzir.com\/en\/wp-content\/uploads\/2018\/12\/Retrofitting-of-concrete-beidge-beams-Afzir-Strengthening-Co..jpg\")
