  Emcoril Traffic grip M

The city of Giurgiu in southern Romania is located on the lower reaches of the Danube, just opposite the Bulgarian border town of Russe on the other bank. The cities are located on the DN5, an important transit road between the two south-eastern European countries.

 

In order to relieve the urban traffic in Giurgiu and reduce noise pollution and CO₂ emissions from national and international traffic in the city, a bypass road was built. This is 5.72 km long and connects the DN5 with the Giurgiu-Russe border crossing.

Special requirements for the road concrete

The Compania Națională de Administrare a Infrastructurii Rutiere (National Road Infrastructure Management Company) commissioned SC PORR Construct SRL, the Romanian subsidiary of Porr AG, an internationally active Austrian construction company, to build the bypass. This was planned with two concrete carriageways in each direction and a central reservation.

 

To protect the fresh concrete carriageway from premature drying and to give it additional grip, an effective concrete curing agent was required as evaporation protection. As Porr AG had already had positive experience with the products of the Emcoril range in the construction of roads and airport runways in Germany, Austria, Poland and also in Romania, the choice fell on Emcoril Traffic grip M, the evaporation protection agent for trafficked surfaces in MC’s range of traffic route construction products.

Exceptionally high evaporation protection with optimal hydration

Liquid concrete curing agents such as Emcoril Traffic grip M are the only practical solution for protecting road concrete placed using slipform pavers equipped with a spray line. This enables even application of the curing agent, allowing a film to form that prevents water from evaporating from the concrete and prevents premature drying due to high temperatures, dry ambient conditions and wind.

 

The special feature of the concrete curing agent Emcoril Traffic grip M: it not only provides very good protection of the concrete, but also meets the slip resistance requirements in road construction. The innovative product is applied to the semi-dry concrete by spraying and offers a high barrier effect of SM ≥ 85 %, exceptionally high evaporation protection and an optimal hydration process in the top layer of concrete. Emcoril Traffic grip M minimises the formation of early shrinkage cracks as well as the rate of carbonation.

Stronger, better grip and faster

Between September and December 2021, 32,500 m³ of concrete were laid on a total area of 130,000 m² during the construction of the bypass. The entire surface was successfully treated with Emcoril Traffic grip M, so that the first new concrete road in Romania for 30 years was opened to traffic four months ahead of schedule in December 2021.
