Optimized compacted concrete for roadways


Optigrave is a roller-compacted road concrete that offers the same performance levels as concrete but at a lower cost and with shorter lay-down times.
It is particularly suitable for the construction of structures bearing very heavy and aggressive traffic, such as industrial platforms, ports, airports and multimodal hubs.

Optigrave provides a shock-resistant, structuring, surfacing course.
Its mechanical characteristics are comparable to those of a classic concrete (NF P 98-170) or a roller-compacted road concrete (NF P 98-128).
In certain circumstances, additional treatments may be included to enhance the pavement’s resistance to specific challenges (chemical, mechanical, climatic) facing the construction.

Optigrave is available in different grain sizes ranging from 0/14 to 0/63 mm. Lay down operations involve the usual equipment (finisher, grader, compactor). Project completion is speedy and the pavement is open to traffic rapidly.

Carbon footprint reduced by at least 50% compared to a reinforced concrete reference solution.

The surface finishing of OPTIGRAVE

The final appearance of an Optigrave surface depends on how it is to be used:

  • unfinished
  • grooved
  • smoothed using a mechanical trowel

The advantages of OPTIGRAVE

  • Withstands even the most severe stress
    • Optigrave can withstand stress generated by even the heaviest construction machinery
    • Optigrave is not punctured by static loads (storage, containers, parked machinery or aircraft)
  • Lay down is easy and costs are optimized
    • Optigrave can be produced at industrial facilities throughout the land (ready mix plant, continuous mixing plant, and even on the job site with the right equipment)
    • Optigrave requires the usual lay-down and transportation equipment (dump truck, grader or finisher, compactor).
  • Short lay down times than traditional concrete
  • Reduced carbon footprint
