Glass textile reinforced concrete crash barrier system (GTRC CRABS) is an alternate for conventional reinforced concrete crash barriers with enhanced energy absorption ability. Some of the key features of the technology are:
• Damage to the vehicle and injury to the passengers are likely to be reduced in a vehicle collision.
• Weight per meter of proposed crash barrier is approximately one-third of that of reinforced concrete crash barrier.
• Customizable for target impact resistance and energy absorption
• Robust connection method to maintain the integrity in the event of collision
• Easy to install due to simple connection mechanism
Technology Benefits Summary, Differentiation & Uniqueness:
- Capable of resisting impact forces and to absorb more energy
- Convenience in transportation, easy to install, replace / repair
- Implementation of GTRC CRABS will lead to safe life for the road users.
- Adaptability for use in narrow space
- Possible to customize for different crash containment level requirements of various countries (design standards
Application & Potential Advantages:
- GTRC CRABS can be used as temporary barriers in various work zones, in toll plazas for controlling the diverted line of traffic, etc.
- Presently designed for low containment crash barrier applications in India
- Reduced weight compared to conventional RC barrier, increased energy absorption, easy transportation, faster implementation, non-corrosive nature etc. are the potential advantages of the product
Development Stage & Development Status Summary:
A ready to use pre-fabricated glass textile reinforced crash barrier system suitable for low containment (P2) crash barrier application according to IRC:6 (2014) was developed and ready for commercialization on non-exclusive basis. The product can also be used for temporary crash barrier applications.
- GTRC CRABS is a novel product and has scope to customize for application in many countries.
