Abstract

The purpose of this report is to provide the results of a recently completed study to geotechnical engineers and engineering geologists responsible for managing and mitigating rockfalls. The study, sponsored by the Colorado Department of Transportation (CDOT), was conducted to provide a better understanding of the durability and performance of several currently available mesh and cable net products that can be used to construct rockfall attenuator systems, for which no design guidelines exist. With the technical support of consultant Yeh and Associates, Inc., of Denver, Colorado, CDOT developed a test site and completed research that resulted in CDOT’s development and construction of an attenuator system at a very difficult rockfall site. The testing described in this circular provides useful data that practitioners may use as they make design decisions when considering attenuator systems.
