CRMCrete Weed Control Barrier

Innovation
CalTrans strives to provide roadside design solutions to reduce the need for recurring maintenance activities such as herbicide application, pruning and mowing. To assist with this effort, a new standard treatment called CRMCrete has been developed to control weed growth under guard rails.
When faced with issues like weed growth beneath metal beam guardrails, which when dry, can provide fuel to become a starting point of a large brush fire, CalTrans came up with a solution. To minimize fire hazards along with reducing the need for recurring maintenance activities such as herbicide application, pruning and mowing, CalTrans now uses a new standard treatment called CRMCrete. CRMCrete Weed Control Barrier is a non-proprietary cementitious product that is more durable than asphalt concrete and physically blocks weed growth. CRMCrete is recommended on all installations of guard rails or their beam barrier where repetitive maintenance activity to control weeds would otherwise be required. It can also be used to provide weed control beyond the gore area, in narrow strips, on side slopes and below roadside sign posts. This product can be colored to specifically match soil color or stamped with a pattern for additional texture. Correctly designed and installed, the life cycle cost of this material should be similar to concrete paving.
