The importance of the HV2 MASH Temporary Barrier

Back in 2022 CalTrans released Supplement to Traffic Safety Systems Guidance: Temporary Barrier Systems with the stated intention of implementing MASH approved Temporary Barriers and the phasing out of industry standard of Temporary Railing (Type K), also known as K-rail.

This transition will be a multi-year phase process beginning in 2025 with a percentage of all jobs requiring temporary barrier in the state to have MASH alternatives. This initiative puts safety at the forefront; K-rail is being phased out over the next several years because it does not meet MASH crash testing standards.

Understanding the potential burden placed on businesses, CalTrans has put forward a phase out period for jobs continuing to use K-rail through December 31 2026, and projects advertised starting January 1, 2027 must use a MASH approved temporary barrier system only.

A MASH Approved Alternative

TrafFix Devices has always been vocal supporters of MASH approved products, and as such have sought to partner and distribute the HV2 barrier which is one of the current CalTrans approved MASH barriers. HV2 is a freestanding temporary barrier product that offers fast installation and exceptional safety for use on bridge decks, highways, and other road maintenance projects.

The barrier’s patented hybrid technology and unique connectors offer high containment and low deflection, while remaining economical to transport and deploy with no time-consuming anchoring required.

SLED: The Obvious choice for Reliability, Simplicity and Efficiency

SLED - The obvious choice for reliability, simplicity, efficiency.

The Sentry Longitudinal Energy Dissipater (SLED) is a narrow, water-filled non-redirective gating crash cushion that is MASH Tested, Passed, and Eligible.

The SLED is designed to shield the end of all permanent and temporary portable barrier shapes including concrete, steel and plastic. The SLED End Treatment does not require foundation anchor bolts to be attached to the road or bridge deck. The complete crash cushion can be installed quickly, with one pick up truck on compacted dirt, gravel, decomposed granite, asphalt or concrete.

Enhancing Road Safety: The Benefits of TL2+®

Delta TL2+ Intelligent Crash Cushion from TrafFix Devices, Inc.

Why TL2+?: TL2+® has been developed and tested to 50Mp/H not 45Mp/H MASH standards, signifying a fundamental change in engineering and design principles in impact attenuators. TrafFix Devices has developed the first fixed crash cushion that is tested to TL2+®.

Why does that matter?Many of the atrial roads that feed our highways as well as on/off ramps increasingly have speed limits in excess of 45 MPH, the maximum testing speed to attain TL-2 accreditation, meaning that these systems no longer provide the safety coverage for areas signposted at 50Mp/H speed limits.

Enhanced Collision Protection: The Delta TL2+® crash cushion is engineered to absorb impact energy during collisions, thereby minimizing the risk of injuries to motorists and passengers. This enhanced collision protection is a testament to the meticulous design and rigorous testing that these crash cushions undergo, ensuring optimal performance when it matters most.
