Colorado Vehicle Tracking Pad Detail

The Rocky Mountains, which pass through Colorado, provide a safe haven for wildlife and a source of freshwater in lakes and glaciers. Throughout the year, Colorado's snowpack provides fresh water to residents and to nearby states. Preserving the quality of this precious water source is a critical responsibility of all residents and government bodies in the state.

Colorado CDPS permitting program

In Colorado, CDPHE's Water Quality Control Division administers the state's CDPS permitting program under the Clean Water Act, including stormwater permits for construction and MS4 operators. The key permit for most contractors is COR400000 (stormwater discharges associated with construction activities). Resources are available to contractors and engineers to develop and implement a site stormwater plan and BMPs required under permit coverage. The Colorado Department of Transportation (CDOT) provides an approved product list and the Erosion Control & Stormwater Quality Guide to inform projects about techniques that have been tried and tested.

CDOT Construction Entrance Detail

The Erosion Control & Stormwater Quality Guide - Chapter 5 includes design and installation criteria for both aggregate-based and pre-fabricated Vehicle Tracking Control (VTC) systems. Aggregate-based tracking pad dimensions are a minimum of 12 feet wide by 70 feet long, excavated to a minimum depth of 6 inches. The excavated area is lined with a class 2 geotextile fabric and covered with 6 inches of aggregate. Pre-fabricated Vehicle tracking pads must be at least 12 feet wide and 35 feet long, and installed according to the manufacturer's specifications.

FODS Pre-Fabricated Trackout Control Mats

FODS construction entrance mats remove more sediment than traditional tracking systems, so it is important to understand how many mats to use for your construction entrance. On CDOT specifications, the standard layout is a 1x5T, which provides 35' of travel or roughly four tire rotations. The CDOT recommends this layout as a replacement for a 70' traditional vehicle tracking control system.

The pre-fabricated FODS trackout control mats can be installed without excavation and on many substrate types. Maintenance is required once sediment builds up to 2.5" between the pyramids. Instead of refreshing with rock, clean the system with a street sweeper or FODS shovel to restore it.

FODS Pre-Approved For Use By Colorado DOT

The FODS Trackout Control System has been pre-approved by the Colorado DOT for use on projects throughout the state. FODS is listed in Chapter 5 of the CDOT Erosion Control & Stormwater Quality Guide. FODS are recommended to be installed in a 5 mat configuration, which provides 35' of length. This configuration is the recommended alternative to a 70' length traditional aggregate construction entrance.

The rockless construction entrance provides a more effective and safer Vehicle Tracking Control (VTP) than traditional rock methods, reducing the risk of rocks entering the active highway lanes. In addition, the FODS reusable construction entrance can be relocated during each phase of the project to reduce costs on each deployment.

Reusable Construction Entrances on Projects

This system has been used throughout the state on various highway projects, including the Central 70 Project, I-25 South Gap Project, and the I-25 North Project. During the Highway 36 collapse in 2019, FODS mats were immediately deployed to begin repairs and demonstrate the versatility of the FODS reusable construction entrance. Our mats have also been used in notable locations, including Phoenix Sky Harbor Airport and Colorado School of Mines. Contractors, engineers, and inspectors have come to trust FODS mats as an effective means of controlling trackout.

Located in central Colorado, FODS LLC is proud to play a role in protecting our state's natural resources. FODS recyclable mats provide an environmentally friendly solution to trackout control with a service life of over 10 years. Our entry into the market marks a shift away from one-time-use VTCs towards reusable, sustainable alternatives. Protecting the environment requires continuous innovation, and we are proud to bring these novel solutions to the table.
