CONCRETE ON A LEVEL SURFACE: an efficient technical solution

AER has real legitimacy in building structures with concrete on a level surface. The know-how we offer our customers is based on expertise dating back to the 1960s.
Our contracting authorities choose concrete on a level surface for airports, urban transport, special works and road pavement under extreme stress (intense traffic flow or heavy loads) for the simple reason that this material is highly resistant to rutting.
In France and abroad, concrete pavement infrastructure is an alternative with high added value.  It offers greater sustainability and resistance to extreme stress (heavy transport vehicles, planes) than the usual solutions, and saves considerable time to manufacture, compared with paving-type solutions.


  • Technique

    The concrete deployed is solid, containing a minimum of 300 kg of cement and including plasticizer-type adjuvants and air-entraining agents. These ensure perfect concrete pavement deployment, and guarantee good frost resistance. Concrete pavement deployment also involves constructing different types of sawn or grouted joints (construction, expansion and contraction-bending). This process, together with the concrete's composition and characteristics, provides excellent resistance to typical pavement stresses such as surface wear, rutting, frost and de-icing salt.

  • Application

    These concrete pavements are chiefly constructed using the mechanical sliding formwork technique combined with manual deployment on specific points or small surfaces. AER can build both thick and thin pavements, with or without dowelling or reinforcement of the continuously reinforced concrete type.

  • Concrete on a level surface is also

    • A unique experience for airport infrastructures
    • An appropriate choice for building and maintaining sustainable roads
    • A durable, attractive, comfortable and modular pavement solution
    • An essential material for special works under extreme stress and in complex environments, or for precision structures.
