Durisol’s aluminum noise barrier wall

HAMILTON — Durisol Ltd. announces the successful crash-test of its Aluminum noise wall product.

A MASH (Manual for Assessing Safety Hardware) TL-4 crash-tested structure-mounted noise barrier was first designed by the roadside safety experts at Safe Roads Engineering. A mock wall was then erected at the test site, and the crash test was completed on December 8, 2020, conducted by third-party provider, Texas A&M Transportation Institute. It was conducted at their proving ground in College Station, TX, USA.

“Durisol’s aluminum noise barrier system provided excellent vehicle stability,” explained Dean C. Alberson, P.E., Ph. D., Senior Research Engineer at Safe Roads Engineering. “Despite the severity of the impact of the crash, the wall panels remained in place and intact, without flying debris and minimal damage.”

“As part of the engineering team that developed the system, it is a rewarding moment when a crash-test is so successful,” added Mark Ayton, Senior Engineer at Safe Roads Engineering. “It means a safer noise barrier system will now be available for installation on bridges across North America.”

The MASH TL-4 testing criteria is dictated by AASHTO (the American Association of State Highway and Transportation Officials). To replicate worst practical conditions, the crash test is conducted with a 10,206 KG (22,500 LB) box truck is tested at speeds of 93 KM/H (58.5 MPH), at an impact angle of 15 degrees.

Aluminum wall panels are a viable noise barrier option in a variety of industries. Loud factories and production facilities, live traffic roads, railway stations and other uses can all take advantage of aluminum wall panels.
