Concrete Step Barrier

A single step can be used if a drop is too far or multiply step on brick work.

Manufactured to australian standards this precast concrete step is a durable and maintenance free step solution. For example specified by the uk highways agency the concrete step barrier has an h2 level of containment 13 tonne coach and a w2 working width. The concrete step barrier is today the stan dardised solution for cast in situ barriers in europe.

Concrete step barrier csb is a vehicle restraint system designed to contain vehicles save lives reduce congestion and be maintenance free for at least 50 years. Csb is designed to withstand impact from an errant vehicle and redirect it along the face of the barrier in the same direction as the traffic flow. It is replacing steel with n2 containment w3 or w4. The deltabloc concrete jersey barrier is an excellent passive traffic safety tool that can deflect cars at 100km h at a 15 angle 257mm deflection.

The standard profile concrete step barrier csb described here figure 1 meets the requirements of td 19 by providing a containment performance class of h2 and a working width of w2 on both faces. The barriers do not move under impact but high vehicles may tilt after striking the barrier so a measurement of this is made. Development of the complete concrete barrier safety restraint solution through further development of the csb profile britpave barrier systems is able to offer a variety of csb shapes and more functionality such as the variable csb which is a single barrier with low working width across two different heights of carriageway. This document provides an overview of csb s positive sustainability credentials by assessing its impact against established.

With water grooves along the span of the step to help stop water building up making step safer.
