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.
