Caltrans position on GRCS

The materials used in GRCS are currently approved in the Caltrans Standard Specifications for use in pavement maintenance projects, and it would depend on site specific conditions (e.g., condition of pavement core layers) whether GRCS or other strategies would be most appropriate to use for a given project.  Caltrans District engineers and project managers are responsible for evaluating the costs and benefits of GRCS or any other available pavement strategies to determine the most cost-effective strategy to use for their pavement project location.

A pavement guide is being developed which will specifically address the use of GRCS.  In the meantime, we consider GRCS to be one of the tools that is currently available in our tool box for pavement maintenance projects.  Again, it is the responsibility of Caltrans Districts to evaluate the costs and benefits of strategies and select the best strategy to use for their pavement project locations.

Once again, thank you for reaching out to share your interests regarding GRCS.  If you have any questions you can contact me or Sri Balasubramanian.
