OPTIGRAVE
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
