Tac Air, a private jet rental company, had begun construction on its new tarmac at the Salt Lake City International Airport when they ran into some serious problems with the underlying sub-base. In order to reach grade and not over excavate the site they chose to go with Nilex’s Mirafi RS380i product.
Once the client removed the existing pavement they found some areas were much worse than reported. The client was unable to excavate any more dirt due to existing utilities, and they could not get the new base to stabilize and make grade.
This required Nilex to re-run all of the calculations to ensure the RS380i would still be heavy enough to perform as expected.
When first reviewed, the ground looked better than initially reported. At that time, Nilex offered an option with Type 2 Geogrid, which was by far the most cost effective way to achieve stabilization. After finding it was worse than initially thought, Nilex reverted back to the original plan to use RS380i. This product allowed them to achieve stabilization and meet grade and at a price point (with the savings of less gravel) that surpassed other geogrid options.
The first section of approximately 6,000 square yards (yd2) took only one day to install with three people and a loader to move and position the rolls. This is only the first of several sections to be completed, with an estimate of approximately 30,000 yd2 in total.
The product used, RS380i, is a revolutionary geotextile created from super high-tenacity polypropylene filaments formed into an innovative weave to provide superior reinforcement strength and soil interaction.
This product helped the contractor meet the requirements of compaction for the area and not go above the designed grade.
Additionally, Nilex provided technical knowledge and Mirafi, the product manufacturer, helped in the design of the roadway structure.
