Task 138, FY 2001, "Recommended Procedures for the Testing of Rock-Fall Barriers" (Jerry D. Higgins). The objectives of this research were to develop levels of performance criteria based on a statistically derived number of rocks a rock-fall barrier can contain for a given rock size and to recommended performance evaluation procedures describing the test parameters to be used for each level of performance criteria. The research has been completed. The agency final report has been submitted to the AASHTO Highway Subcommittee on Materials for subcommittee use and distribution. (NCHRP Staff: T.G. Hess)
