ASPHALTEX is a biaxially oriented (biaxial) synthetic geogrid made of high modulus polyester (ASPHALTEX PET), polyvinyl alcohol (ASPHALTEX PVA), basalt (ASPHALTEX BASALT) or glass (ASPHALTEX GLASS), impregnated with bitumen dispersion. The square or orthogonal cellular structure is stitched with strong knots.
The geogrid can be produced with different mesh sizes and standard tensile strengths ranging from 20 to 200 kN/m. Width of the material is from 1,0 to 5,2 m, what makes installation more efficient by greatly reducing the need to cut and overlap panels.
The geogrid is resistant to high temperatures when laying asphalt concrete layers, to chemically aggressive environments, as well as to the influence of biochemical factors. The material has high strength characteristics and good adhesion to asphalt concrete.
Functions of ASPHALTEX:
Geogrid ASPHALTEX improves the elastic modulus of a roadbed while distributing loads for greater roadway longevity and performance.
The use of ASPHALTEX in an asphaltic pavement system mitigates the risk of reflective crack formation. The geocomposite reinforcement layer redistributes stresses horizontally in the overall system, thus preventing stress from concentrating and migrating upward to the surface as a crack.
The high-strength performance of ASPHALTEX redistributes loads across the entire area of the reinforced road surface. This prevents the formation of wheel ruts, even in high temperature environments.
