The geosynthetic layer was terminated into a trench system, allowing captured moisture to flow into a dry well through controlled drainage.
Capillary suction from MIRAFI® H2Ri moved moisture away from the subgrade, increasing the pavement’s resilient modulus and reducing damage from saturated soils
Jackson averages 465 inches (1,181 cm) of snow annually
MIRAFI H2Ri enhances the longevity of flexible pavements by providing mechanical and hydraulic stabilization
From poor subgrade performance to roadway resilience
MIRAFI H2Rx repairs, weak and cracked roads in traffic-heavy Pulau Indah, Malaysia. MIRAFI H2Rx was installed for separation, mechanical stabilization and moisture management, providing the solution to building durable climate-resilient roadways.
When traditional sand bunds fail: A GEOTUBE marine solution for land reclamation
When traditional sand bund construction failed on an extremely soft marine clay seabed, GEOTUBE® Marine systems provided a stable containment solution that helped advance a land reclamation project for 112 acres.
GSE HD geomembrane lined salt ponds ensure long-term brine containment
GSE® HD geomembrane lined over 3.4 million m² of evaporation ponds to prevent brine seepage under extreme heat and UV exposure. This continuous barrier eliminated salt discharge and protected the surrounding environment.
The Town of Jackson, Wyoming, needed to resurface Flat Creek Drive, a city street that was in poor condition due to potholes and large cracks. The roadway is frequently used by the town and the public. To address the problem with a long-term solution, the town needed to find a pavement system that can stand up to high water flows on soft soils.
Jackson averages 465 inches (1,181 cm) of snow annually. The Teton County Fairgrounds is one location where plowed snow is stored in the Town. When the snow melts, water flows from the stored snow drains toward Flat Creek Dr., further degrading the roadway.
Knowing that water is the biggest threat to the performance of and durability of roadways, the town planned for rehabilitation for Flat Creek Dr. The project engineer had previous experience with MIRAFI® RSi and knew that it was an excellent product for roadway stabilization, but selected MIRAFI H2Ri to benefit from its active moisture management properties. MIRAFI H2Ri enhances the longevity of flexible pavements by providing mechanical and hydraulic stabilization. Engineered with wicking yarns, it aggressively manages moisture by actively drawing water out and pulling it away from the roadway in both saturated and unsaturated conditions.
Approximately 9,000 y2 (7,525 m2) of MIRAFI H2Ri was used to stabilize the roadway, terminating into a trench. As water was removed from the roadway, it drained into the trench, which eventually fed into a dry well.
Perched water below roadways will weaken the subgrade leading to damage including potholes and rutting. Using a geosynthetic with moisture management, like MIRAFI H2Ri, is an effective way to mitigate these issues in both paved and unpaved roadways. Using capillary suction, the solution moves moisture away from the roadway, leading to a greater resilient modulus and stable conditions. The rehabilitated pavement section of Flat Creek Dr. has been through one spring melting cycle without any issues.
