Basfiber® reinforcing mesh for roads

Products - Basfiber® reinforcing mesh for roads Reinforcing mesh for roads is designed for pavement reinforcement. It’s successfully used in construction, repair and renovation of roads and acts as a reinforcement layer. The key functions of material are even distribution of external load over the whole roadway surface, stress-relieving of asphalt concrete pavement and also tensile strength improvement of finish asphalt coat.

 

Production technology

Sewing-knitting technology, used for mesh production, allows to achieve the best realization of physical and mechanical properties of basalt fiber in the end product.

 

Application

Basfiber® mesh clothes for roads are placed on a pre-cleaned surface with a bitumen emulsion applied. Good adhesion of basalt mesh with pavement base is achieved by means of bitumen-polymer dispersion, the Basfiber® mesh is impregnated with. The impregnating composition, as well as basalt fiber itself, is environment friendly.

To simplify the process of reinforcement mesh rolling on road base, basalt mesh is produced both with open cell and closed cell. Closed cell protects roller from bitumen pickup, which significantly accelerates the placement process.

 

Advantages of Basfiber® reinforcement mesh for roads

Basfiber® basalt reinforcement mesh for roads is produced of high-quality continuous basalt fiber, which considerably outperforms in all parameters Е-glass, often used in mesh for roads production:

  • 150 degree higher the upper operating temperature limit,
  • 5 times greater chemical resistance to moisture and salts agents attacks
  • 10 times lower hygroscopicity

Geogrids operation

Under heat cycling and external mechanical loads asphalt concrete pavement is stretched. It results in micro cracks formation in the film of impregnating composition on geogrid, produced of Е-glass, therefore reinforcing fiber remains unprotected against moisture and salts agents, which are widely used in winter.
Salt solution action leads to destruction of such mesh, with the result that the road pavement remains without reinforcement layer.

Since basalt fiber has five times greater chemical resistance compared to glass fiber, Basfiber® mesh for roads isn’t destroyed under salts solutions action and successfully performs its reinforcing functions under all operating conditions.

Besides that, because of extremely low hydroscopicity of basalt fiber, natural fiber corrosion process in the Basfiber® mesh for roads goes considerably slower, than in case of E-glass mesh.

Thus, Basfiber® mesh application allows to considerably increase the quality of road pavement, to increase service life and time between overhauls, decelerate the process of cracks and rutting formation compared to meshes produced of Е-glass.

 

Basfiber® reinforcing mesh for construction.

Products - Basfiber® reinforcing mesh for roadsBasalt reinforcing mesh with alkali resistant coating was developed to prevent cracks as well as for reinforcement of mortars and non load bearing concrete.

The higher tensile strength of this product, compared to E-glass or steel, increases impact resistance and prevents from cracks appearance. This mesh can meet the expectations and strict requirements of most demanding companies from construction market.

Our high-performance, alkali-resistant basalt mesh will not rot, rust or corrode, and it provides increased strength in different cementitious applications. Thanks to its lightweight, easy install and use basalt mesh Basfiber® will be superior alternatives to steel.

 

Advantages and benefits:

  • Specially developed coating provides good adhesion with concrete to improve tensile strength and increase impact resistance.
  • High mechanical strength and modulus.
  • High resistance to chemical aggressive environment and in particular high alkali resistance won’t allow appearance of rust or corrode.
  • Minimizes crack width and spread
  • Easy to install and use. No special equipment is required.
  • Extremely low coefficient of heat conductivity significantly reduces heat transfer from building exteriors to interiors and significantly improves energy efficiency.
  • Much higher electrical resistance compared to steel.
