Paved and unpaved roads
Pavements that are to be constructed on expansive or slushy soils with soft clay as subgrade, need a strong long-lasting separator above subgrade to ensure performance over the service life of the pavement. Using StrataTex HSR™ on subgrade not only provides the separation required but also improves the modulus of the granular layer above subgrade owing to its tensile modulus.
StrataTex HSR™, when placed above subgrade, improves the modulus or layer coefficient of the granular material above by reinforcing that layer based on friction, interaction, and tensile strength properties of StrataTex HSR™. StrataTex HSR™ possesses excellent permeability and strength compared to nonwoven geotextiles which cater to a higher flow of water, ensuring serviceability performance of the pavement.
