8.2.8.2
Testing. No formal crash testing has been conducted; however, the mass of this type
of concrete construction should perform at least as well as a concrete median (Figure 26).
8.2.9
Steel Cable Barriers
8.2.9.1
Description. As shown in Figure 33, there are several configurations for steel cable
barriers. Site requirements, configuration, and environment must be carefully considered prior to
selecting a cable system for a particular application.
8.2.9.2
Testing. Systems such as those shown in Figure 33 have not been formally tested.
However, two 3/4-inch (1.9-cm) diameter cables attached to a 200-foot section of fence, minus
fabric, with deadman anchors at both ends were tested with a 4,000-pound (1,818-kg) vehicle at
52 mph (84 kph). The vehicle was stopped within 13 feet (4 m) and then pushed back to the
impact point.
8.2.10
Steel Cable-Reinforced Chain Link Fencing
8.2.10.1  Description. Without some reinforcement, a standard chain-link fence can be
penetrated easily by a light vehicle with little or no damage. The designs shown in Figures 34
through 40 provide a cost-effective method for reinforcing standard chain link fences against the
threat of penetration by light vehicles. For additional considerations, information, and design
guidance relating to the reinforcing of fencing and gates, refer to MIL-HDBK 1013/10.
