The objective of this project was to develop a Type III barricade system with a mounted sign which successfully met American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH), Second Edition (1) criteria. The research team first reviewed relevant research and state standards to lay a foundation for the design effort. The research team subsequently developed a design for testing and evaluation according to MASH guidelines. The purpose of the tests reported herein was to assess the performance of the Type III barricade with mounted sign according to the safety-performance evaluation guidelines for MASH Test Level 3 (TL-3). The Type III barricade with mounted sign successfully met the performance criteria. This report provides details on the Type III barricade with mounted sign, results of the MASH crash tests, performance assessments, and recommendations for implementation.
