North America’s first MASH TL-5 integrated noise barrier and vehicle restraint system
Leading the way in noise protection and safety, Durisol is proud to bring a MASH TL-5 Crash-Tested Noise Barrier System to the Canadian and U.S. transportation marketplace. Combining our industry leading dual-sided sound absorptive panel technology with a precast concrete safety barrier, we address noise abatement while meeting the highest level of safety standards.
The future of safety
Meeting the AASHTO MASH TL-5 MASH Test Level requirements ensures compliance with the most stringent safety standards. Through crash testing, the system demonstrated the ability to withstand impacts from heavy vehicles, including a full tractor trailer. Translating to real world performance, our roadside safety barrier helps to redirect vehicles, keeping them on the road, and keeping drivers safe. Read more about MASH TL-5.
Applications
Ideal for permanent highway and roadway noise walls, our system can be designed in the clear zone where space limitations exist, or on the center median to benefit from noise reduction on both sides of a roadway. The foundationless advantage also creates opportunity for temporary projects.
Meets the following MASH TL-5 test criteria:
Sectors
Main Features and Benefits
FOUNDATIONLESS
- Free-standing, modular barrier engineered to simplify construction.
- Reduces associated design risks and speeds up the noise wall installation portion of a project.
- Shallow anchoring depth requires only 6.69 in (17 cm) for anchoring and can easily be removed if ever required.
CRASH-TESTED RELIABILITY
- Proven to withstand rigorous MASH TL-5 testing, ensuring safety performance transportation owners can rely on.
- Additional concrete beam is incorporated to protect the wall system where truck contact occurs, providing additional protection for the noise barrier panels and ensuring durability during collisions.
MAXIMUM NOISE REDUCTION
- Durisol’s double-sided absorptive panels effectively reduce noise and eliminate reverberation.
- Minimal distance to the noise source as an effective noise mitigation strategy.
SPACE EFFICIENCY
- Integrated safety and noise barrier structure for efficient land use.
PRECAST CONCRETE
- Only a total precast concrete barrier system can provide the life span highways and roadways demand.
