Deltabloc DB80 Road Barrier
Crash Tested to MASH TL-3
System Overview
The Deltabloc DB80 is a free-standing precast concrete road barrier, suitable for permanent and temporary applications. A durable and high performing road barrier system that is fully crash tested to MASH TL-3.
This F-type concrete road barrier is remarkably light, flexible and rigid, as well as being RMS approved to minimise impacts from vehicles travelling up to 100km/hr in NSW & VIC, and 80km/hr in QLD.
Available in 2, 4 and 6 metre lengths, their unique design allows for fast truck-mounted crane installation.
The main advantages of the DB80 F-Shape system from Deltabloc over traditional portable concrete barriers are:
- Energy absorbing
- Quick and easy installation
- Economical
- No damage after low and medium impact because off butt joint inserts
- Easy replacement of damaged barriers
- Identical barrier connections at either end
DELTABLOC Barriers are crashworthy and have been tested to MASH 2019 and EN1317 testing procedures.
TL3 F Type Concrete Crash Barrier - Australian Road Safety
The DB 80 F-Shape road barrier has been successfully tested according to MASH Test Level 3 (TL-3) Please contact Jaybro on 1300 885 364 for further Deltabloc DB80 specifications.
Function
The patented Deltabloc technology is based on the well-proven tension bar in combination with the unique coupling. The precast concrete units are connected like a chain and provide specific flexibility. Elastomer bearings between the single barriers ensure controlled damping of peak loads. This guarantees reliable breakthrough prevention for heavy vehicles and soft impact behaviour for small passenger cars. DELTABLOC technology has been optimised in more than 130 full-scale crash tests, allowing DELTABLOC barriers to deliver the best impact severity results available.Applications
DELTABLOC barriers can be used in many applications such as:
- General Road Maintenance
- Road Constructions
- Toll Plazas
- Road Resurfacing
- Excavation or culvert protection
- Bridge Repairs
- Median or verge installations
System Design
TENSION BAR
The patented tension bar is incorporated within each DELTABLOC barrier. Tension bars are available in different strengths to accommodate different containment levels required.
COUPLING
The patented coupling is used to connect the tension bars within each barrier, enabling a continuous connection from the beginning to the end of the barrier deployment.
