Road Construction
Turning any soil — even chernozem, peat or heavy clay — into the main building material, with the Road Graphene Modifier SV2.
Soil stabilisation method
ATTIMAR is a world leader in the production of the most durable material in existence — graphene. One of the areas of our activity is the development of affordable technologies for "combining" graphene with natural minerals. We managed to connect an aluminosilicate mineral with the graphene crystal lattice at the molecular level.
We modified it with graphene and subsequently synthesised a natural mineral — pozzolana. Since pozzolana is an active mineral additive and is widely used in the production of cements, our next step was the development of modifiers for the production of concrete and for road construction.
Our Road Graphene Modifier SV2 (RGM SV2) is a unique product of its kind: it is a real complex binder. As an activator, it accelerates the hydration processes of Portland cement, simultaneously creating conditions for polymer reactions and involving graphene in the synthesis of aluminosilicate compounds.
Practical experience of using RGM SV2 with various cements and other soil stabilisation products has shown the correctness of our approach to creating the product. Regardless of the characteristics of the soil and stabilising components, one RGM SV2 modifier and its correct dosage are sufficient.
Significant advantages of RGM SV2 technology in every single aspect change the game forever.
Engineering
Horizontal stresses in road pavement appear when vehicles brake, when driving speed changes, and on steep slopes and turns. These stresses reach their greatest values at the contact boundary between the coating and the base, which can lead to deformation of the coating or its displacement due to high positive temperatures.
Destruction of the coating from horizontal forces can be avoided by using bitumen–mineral compositions for the underlying layer, characterised by values of the angle of internal friction and adhesion that provide shear resistance to the entire coating layer, including under the condition of unexpected braking of the vehicle. The basic criterion for the suitability of road pavements on foundations made of reinforced soils is precisely the shear resistance in the plane of the interface between the base and the coating.
On site
During the construction of the road base, any soil, RGM SV2 modifier and cement are mixed on site, creating a powerful waterproof monolithic slab. Any soil — even the most difficult, such as chernozem, peat or heavy clay — becomes the main building material.
Costs for excavation work and building materials such as sand and crushed stone are significantly reduced. The consumption rate of traditionally expensive materials — asphalt and bitumen — is reduced, and construction time is cut.
The productivity of a mechanised detachment is up to 1 km of road per day. Building a highway with RGM SV2 is almost completely mechanised, which reduces labour and costs.
CO₂ emissions during construction are reduced by 5–6 times, since less cement is needed to achieve the required result with RGM SV2.
