The City of Ocala has seen significant growth in the past decade, spurring increased traffic congestion. To alleviate these challenges, the city planned a road extension including a new four-lane, divided highway along the Northwest side of Ocala. This portion of the project was built on a new embankment constructed through a gravel pit of an active mine.
The planned route traversed a section of the land that consists of deep fill placed over a large pit used during mining operations. Construction began in the summer of 2024, during a period of heavy rainfall that saturated the subgrade and created weak, rut-prone soils. These soft areas posed significant challenges, especially where the planned route crossed deep fill over a former mining pit. Voids, loose soils and long-term settlement could adversely affect the performance of the roadway as well as its lifespan.
To address those concerns, engineers implemented a multi-layer geosynthetic stabilization system using 25,000 square yards of MIRAFI RSi-Series. Instead of removing 2 to 4 feet of existing material as required in conventional construction, the MIRAFI RSi design provides a faster, more efficient solution. A two-layer system was implemented: MIRAFI RS580i for initial stabilization and MIRAFI RS380i for reinforcing the roadway base. This approach quickly created a firm, compacted platform, offering both reinforcement and separation to ensure long-term roadway performance while saving time and materials.
The new highway will significantly enhance the region’s transportation network, support economic growth and improve the quality of life for the community. The highway features modern infrastructure, including advanced drainage systems, sound barriers and pedestrian walkways to ensure safety and convenience for all users. Additionally, the design incorporates environmentally friendly practices, such as the use of recycled materials and the preservation of surrounding natural habitats.
