Crash Cushion (Self Restoring Crash Cushion) by Avantech Engineering Consortium Pvt. Ltd.

REACT-350 is self-restoring Crash Cushion that absorbs the energy using smart plastic cylinders made of high molecular weight, high density polyethylene (HMW/HDPE) plastic, they typically regain up to 90% of their original shape after an impact. REACT—meets requirements of NCHRP-350 Test Level-3 as a re-directive, non-gating crash cushion.

The REACT- 350 of Crash cushions is designed for permanent and work zone sites where impacts are expected more than 3 times per year or where traffic congestion and maintenance management is concern for work crews.

 

The REACT-350-II is highly efficient, reusable crash cushion that features 6 high molecular weight/high density polythene (HMW/HDPE) cylinders attached to a steel base track. The system is NCHRP 350 Test Level complaint as a redirective, non-gating crash cushion. The REACT- II has proven self-restoring characteristics after impacted at 62 kph by a 1,808 lb (820 kg) car, or by a 4,409 lb (2,000kg) pick-up truck. The REACT-II can be used to shield narrow hazards of up to 3’ (914mm) wide.

 

Features:

 

• Various cylinder wall thicknesses to accommodate both light cars and heavier high-centre-of-gravity vehicles. • Extremely efficient, energy absorbing, reusable HMW/HDPE cylinders. • Minimal maintenance and repair. • Delivered pre-assembled. • Low lifecycle costs. • Optional cylinder covers available.

 

Typical Applications:

 

• Portable or permanent concrete barriers. • Bridge piers • Bridge parapets • Square blocks • W-beam guardrail • Thrie-beam guardrail • Self-contained, steel backup • Concrete back-up structure

 

Installation and Repair Advantages • When impacted in NCHRP-350 testing, the system typically regains 90% of its original shape and capacity with minimal maintenance and repair. • Units arrive fully assembled. • NCHRP 350 testing impacts require little to no major component replacement resulting in low life cycle cost. • Installs of new or existing concrete pad or asphalt. • Anchorage options include: asphalt, concrete, or soil-drive pile.
