What is the Trackout & Carryout Problem?

  • Trackout dirt, mud, stone, or other debris tracked or carried out onto a paved public road by a vehicle leaving a construction site.
  • Dirt, stone, and mud adhering to tires, the exterior, or undercarriage of a vehicle leaving a construction site that falls onto a paved public roadway.
  • Traces of dirt, stone, or other bulk material that spill onto a paved public road from an improperly loaded haul vehicle leaving a construction site.
  • Dirt, stone, and mud leaving an unpaved access road going onto a paved public roadway.

Sources of particulate matter (PM), a regulated air pollutant, are when the material deposited on the pavement is lifted back into the atmosphere – or “re-entrained”-by the tires of vehicles passing over the matter. A large portion of particulate matter in the metropolitan area is caused by vehicle re-entrainment. Trackout and carryout remaining on roads can also lead to water pollution in the form of suspended sediment when carried to bodies of water by stormwater runoff.

According to many county and municipal governmental agencies, trackout control is required for excavation sites having a disturbed surface area from which material is hauled on or off-site. Be sure to contact your local governmental agency for your area’s exact requirement. It’s also worth noting that trackout could also be a violation of your areas hauling and stormwater ordinances.

The Trackout & Carryout Control Solution

Installing our trackout mats here at RubberForm will prevent trackout and carryout of particulate matter from dirt, mud, stone, or other debris onto paved public roadways. The simplest and quickest control technique is the installation of a trackout control mat. This is a modular, customizable rumble mat that consists of a ground-level, hard yet flexible rubber and plastic mat that when driven over creates a rumble designed to remove PM from vehicles tires. Our trackout control systems here at RubberForm are easy to deploy, clean, and can be stored and reused for years to come.

Why Our Trackout Control Mats are Better Than Current Standards

Gravel Trackout Pad

Gravel trackout pads are most commonly used as stabilized exits on excavation and construction sites. These are less effective than our mats at RubberForm and the gravel trackout pads are harder to keep clean and maintained. A typical layout is 20 feet wide by a minimum of 50 feet long — most are 100 feet long with a 30-foot width with number 2 coarse aggregate and are at least 6 inches deep. They are more expensive over time and are hard to maintain. The mats at RubberForm are the best and most cost-effective long-term choice. It can be moved and reused over time, unlike gravel trackout pads.

Wash Pit

Wash Pits are very effective at removing the debris from the trucks leaving the job site, however, they are extremely expensive to install and maintain. They are very effective when used in conjunction with the mats at RubberForm to remove dirt, stone, and debris from tires and undercarriages of vehicles. You can install our trackout mats before or after the wash pit. The wash pit trackout mat combo is best when they are used for extended projects or projects with high levels of debris.

Temporary paved construction access is an effective method of sediment control, but it is also a more expensive option. The paved surface must extend at least 100 feet from the point of intersection with the public road and be at least 20 feet wide. Solutions to minimize trackout onto the public roadways are not always 100% effective. For debris leaving the job site, remove sediment and rock from the pavement as soon as possible, but no later than the end of the workday on the same it has been deposited on the paved road.
