Abstract

A variety of portable safety and security barriers for directing traffic (public events, sports facilities, etc.), and securing private and public locations against access (court houses, schools, etc.) have been developed. Some higher capacity systems have been developed for use on and around high speed automobile racing tracks. Generally, the barriers are hollow, plastic composite walls and use dead weight fill (sand, water) to resist impact without interconnection to the ground. Heavier solid systems, such as a concrete Jersey Wall type configuration, are used in highway construction as well. These are much more expensive and require heavy equipment to relocate them. Few of the filled, lightweight systems have been crash tested to meet federal standards, although some users have conducted their own impact tests. Typically, manufacturers are small businesses without the resources to conduct federal tests similar to crash tests of bridge guard rails. Thus, developing a comparable impact test method to conduct dependable preliminary tests has great merit.
