Mirafi HPa integrated subgrade stabilization geotextiles are multi-function combination products created from super high-tenacity polypropylene yarns formed into an innovative woven structure to provide all the relevant functions for roads and other load support platforms constructed on soft subgrades. The super high tenacity polypropylene yarns allow mobilisation of tensile resistance for reinforcement benefits at low working strains of 2%. The innovative woven structure results in a product that has high water flow for rapid dissipation of excess pore pressures induced as the wheel load passes while serving as a separator to prevent the intermixing of soft subgrade soil and the structural aggregate layer, thereby preventing the deterioration of the aggregate layer over time. The innovative woven structure also results in a product that has superior interaction coefficient to provide confinement to the lateral spreading of aggregate at the interface of the geotextile and the structural aggregate layer.
