U14B prefabricated concrete barriers – traffic protection

Type U14B concrete barriers are a key component of traffic safety systems. The prefabricated concrete barrier features the New Jersey profile, designed to effectively restrain and divert vehicles. The U14B meets the requirements of containment class H2 according to EN 1317, guaranteeing protection in collisions with speeds up to 70 km/h.

The construction of U14B concrete barriers is based on a monolithic reinforced concrete element with a modular length of 4 meters. Concrete class C40/50 provides a minimum compressive strength of 50 MPa. Main reinforcement made of A-IIIN steel (RB500W) with a diameter of 12-16 mm, distributed according to static and dynamic requirements.

Production technology of concrete road barriers

The manufacturing process of U14B concrete road barriers is carried out under controlled factory conditions. Forming in precision steel dies guarantees the repeatability of the profile geometry. High-frequency vibration ensures homogeneity of the concrete structure and elimination of air voids.

Each concrete road barrier undergoes a maturation process in the post-tensioning chambers. Within 24 hours, the component reaches 70% of the target strength. This is followed by a 28-day seasoning period, during which the concrete barriers achieve full strength parameters and are ready for crash tests.

Profile and geometry of the U14B barrier

The distinctive shape of New Jersey-type concrete barriers was designed based on crash tests. The lower part with a 55° slope lifts the vehicle’s wheel and directs it back onto the roadway. The upper part with a slope of 84° prevents the vehicle from tipping over the barrier.

The U14B model has an overall height of 1070 mm, a base width of 600 mm and a crown width of 240 mm. The concrete barrier is equipped with system face connectors that allow tight connection of successive segments. The weight of a single 4-meter module is about 5200 kg, which ensures stability without the need for anchoring.

Advantages of U14B concrete barriers

Highest level of road safety

U14B concrete barriers meet the requirements of restraint class H2 according to PN-EN 1317. They effectively restrain vehicles weighing up to 13 tons at an impact angle of 20°. The redirection system minimizes the consequences of a collision, protecting both accident participants and other road users.

Durability and resistance of concrete barriers

Concrete barriers have a lifespan of more than 50 years without replacement. C40/50 grade concrete provides resistance to weathering, de-icing salts and freeze-thaw cycles. The surface requires no maintenance or painting throughout its life.

Quick installation without foundation

The U14B concrete barrier does not require anchoring to the ground due to its high dead weight. Installation consists of placing the modules with a crane and connecting them with system connectors. The laying rate is 200-300 meters per day by a 3-person team with a crane.

Versatility of road barrier applications

U14B concrete road barriers used as lane separation, roadway edge protection, protection of bridge structures. Can be used as temporary barriers during road repairs. Modular system allows easy adaptation to the route.

Reduction of traffic noise

The solid construction of the concrete road barrier effectively suppresses noise from traffic. Sound level reduction of 8-12 dB for areas behind the barrier. Can be integrated with acoustic screens mounted on the barrier crown.

Minimum maintenance requirements

Concrete barriers do not require periodic maintenance beyond post-crash inspections. No need to replace corroded components as in steel barriers. Damaged modules are easily replaced without dismantling the entire section.

Cost-effectiveness in the long term

Despite the higher initial price, U14B concrete barriers are cheaper to operate than steel barriers. No painting costs, replacement of damaged guides, repairs after minor collisions. Total cost of ownership (TCO) lower by 30-40% over 25 years.

Resistance to vandalism and theft

Monolithic construction of concrete barriers prevents theft of elements for scrap. Graffiti-resistant surface – easy removal of paint with special preparations. The massiveness of the structure discourages attempts to damage or move it.
