This app was developed as part of NCHRP Project 22-28. The objective of this project was to develop a field guide to assist highway agencies in deciding when guardrails need to be repaired based on the observed damage. The app was developed to provide practicle means to evaluate the field conditions of their w-beam guardrail.
This app walks the inspector through the steps required for a full evaluation over the condition of w-beam guardrail. See the GCA links for more information or to test out the app.
