Supa-Trac is heavy duty, portable roadway and event flooring designed to support heavy pedestrian foot traffic, forklifts with pneumatic tires, light trucks, vehicle traffic and static displays.
Supa-Trac X-Press is lightweight, medium duty, portable roadway and event flooring designed to support heavy pedestrian foot traffic and static displays.
Both panels are similar in design and share the same assembly attachment system, but Supa-Trac X-Press panels are thinner and lighter. Supa-Trac panels have a static compression capacity of 36,000 lb/sq ft, while the compression capacity for Supa Trac X-Press panels is 36,000 lb/sq/ft. Panels can be used for both indoor and outdoor events where a solid non-skid surface is required and the existing surface must be protected. Grass is protected from being trampled and air, water and light can reach the surface. Supa-Trac and Supa-Trac X-Press panels can be used in all weather conditions as they are molded with high-impact polypropylene with UV inhibitors preventing damage from long UV exposure. The purpose of this guide is to review all aspects of the safe use of Supa-Trac and Supa-Trac X-Press event roadway and flooring.

Supa-Trac and Supa-Trac X-Press panels are transported to job sites using 53’ and 48” enclosed trailers or 48’ flatbed trailers in the following volumes per trailer:
|53’ enclosed trailer||21,720 sq ft||28,290 sq ft|
|48’ enclosed trailer||20,272 sq ft||26,404 sq ft|
|48’ flatbed||21,720 sq ft||28,290 sq ft|
Supa-Trac panels are shipped in 5 panel preassembled sections. Each pallet has 32 layers of preassembled sections, for a total of 160 panels per pallet.
Supa-Trac X-Press panels are shipped in 5 panel preassembled sections. Each pallet has 41 layers of preassembled sections, for a total of 205 panels per pallet.
To prepare for shipping, the full pallet should be securely strapped to prevent any movement of panels on the pallet.
A trailer is loaded 2 strapped pallets high with each row strapped and winched in compliance with DOT Federal Motor Carrier Safety Regulation 49 CFR 393.100 – 393.114.
Pallets transported in closed trailers must be secured to ensure the load will not shift in transport.
Before installing Supa-Trac, the load bearing properties of the soil to be covered must be evaluated to determine it’s suitability for the loads placed on the Supa-Trac panels. The California Bearing Ratio (CBR) rating guidelines are used for this purpose. These guidelines and test method were developed in the 1930’s to determine the quality of soil where roads are to be constructed and are used to determine what is required of the roadbed.
CBR testing is a measurement of the pressure required to penetrate a soil sample with a standard plunger of a given area. CBR tests yield a % value that compares the surface being tested, to the load bearing capacity of well-graded crushed California limestone, with a CBR value of 100. Samples can be evaluated on equipment in a lab or portable testing devices are available to perform field-testing at the job site.
The formula for CBR is:
CBR = P/Ps (100)
P = measured pressure required to reach penetration depth of sight soil (lb/in sq)
Ps = pressure to reach equal penetration in standard soil (lb/in sq)
The higher the CBR rating, the harder the surface and the greater the support under the Supa-Trac panels. Higher CBR ratings enable higher loads to travel over the temporary roadbed system. The load capacity rating of Supa-Trac assumes a CBR rating of 100.
|Static Compression Rating at a CBR = 100||36,000 lbs/sq ft||36,000 lbs/sq ft|
Before installation the sight must be inspected and any large rocks or debris removed. Any large holes or indentations should be graded or filled in. If possible, CBR testing should be completed or estimates should be made using a sufficient safety factor. Soil conditions may vary over the installation area, so care must be taken to evaluate the total area to be covered. It is the responsibility of the installer to ensure the surface is capable of supporting the loads required and does not have any large holes or irregularities that will affect the structural integrity of the Supa-Trac panels. CBR ratings can be obtained through lab measurements or using portable CBR measuring device, Measurements should be taken over the total area of the installation as soil conditions may vary.
If the sub-surface is dirt, a geotextile should be used to keep Supa-Trac panels clean and to prevent water from building up at low areas under the installation. The geotextile panel will also increase the CBR of the subsurface if there is any question concerning the suitability of the soil.
The following assembly instructions are for Supa-Trac roadway and flooring panels. Supa-Trac X-Press panels are similar in surface area and the installation process is identical, with the exception of the use of locking clips. When installing Supa-Trac X-Press flooring, ignore all references to locking clips.
Supa-Trac and Supa-Trac X-Press panels can be cleaned using a high-pressure spray washer. High-pressure steam cleaners should never be used.
If a Supa-Trac or Supa-Trac X-Press panel is damaged, it must be recycled.
