• Description:
  Hydraulic laboratory experiments were conducted to determine the effectiveness of surplus concrete traffic barriers when used as riprap to protect against scour and erosion. Even though the traffic barriers have a poor shape for riprap, engineers are interested in knowing what size rock riprap would be approximately equivalent to the traffic barriers, especially, if the traffic barriers are available as a surplus resource. The traffic barriers were modeled at a 1:20 scale and compared to rounded and crushed rock riprap by testing on a flat bed as well as on a site specific embankment model that was being considered for application for some surplus traffic barriers left from construction around the Atlanta, Georgia Airport. The traffic barriers are equivalent to 2' to 2.5' diameter rock riprap sizes.
