MASH TL-4 Crash-Tested System

Noise Walls - Crash-Tested Barriers

Crash-tested to real-life impacts, the integrated precast concrete crash railing stabilizes box trucks in a collision.

path

Durisol’s MASH TL-4 System is a modular, ground-mounted absorptive noise barrier system. The MASH TL-4 is host to an integrated precast concrete crash railing and an inertial impact panel to stabilize box trucks in collisions. Our system has been successfully tested under MASH (Manual for Assessing Safety Hardware) TL-4 conditions, proving its ability to hold up when needed most and not fail in real world scenarios.

CRASH-TESTED

  • A barrier system proven to withstand MASH TL-4 impact loads.

ADDED SAFETY

  • Inertial impact panel protects the wall and stabilizes trucks while the additional precast concrete panel provides another layer of safety.

EASY INSTALL

  • Our lightweight system and modular design require minimal installation equipment and crew.

CUSTOM FINISHES

Design Details at a Glance

Durisol® MASH TL-4 System is a modular, absorptive, ground-mounted noise barrier system just like the TL-3 system – however, it has been tested to MASH TL-4 conditions and includes an integrated impact panel for trucks.

  • 39” (1,000mm) high precast steel reinforced concrete single slope traffic barrier with proprietary connection to the noise barrier post.
  • Integral inertial impact panel placed at 10’ elevation to ensure protection of the wall from soft portions of the truck.
  • W-10 (W250) post ground mounted post design.
  • Overall crash tested height of noise barrier system installation above pavement was 17.3’ (5.273m), however, designs can vary.
