AFH 10-222 Volume 14 1 August 2008 94 4.5.5.2. Passive Vehicle Barriers. Unlike active barriers, passive vehicle barriers have no moving parts. Their effectiveness relies upon their ability to absorb energy and transmit that energy into the foundation. The following paragraphs briefly describe some types of passive vehicle barriers. 4.5.5.2.1. Jersey Barriers. Jersey barriers (Figure 4.21) are typically employed for countermobility around entry control points and approach avenues. They can be staggered on roads to create serpentine paths, forcing drivers to slow down to negotiate curves prior to reaching the entry point. They can also be used to establish site boundaries. To be an effective vehicle barriers, they must be anchored to the surface and/or cabled together (along straight paths) to provide added strength and resistance. Figure 4.21. Jersey Barrier.
AFH 10-222 Volume 14 1 August 2008 95 4.5.5.2.2. Fixed Bollards. Fixed bollards are excellent obstacles for anti-ram protection. In the field environments, these obstacles can be constructed of ½inch thick steel pipe about 8 inches in diameter and 7 feet long. The pipes are filled with concrete and anchored into a 4-foot concrete footing so they project 3 feet above the ground (Figure 4.22). The pipes should be spaced no more than 4 feet apart. Fixed bollards can be placed inside or outside existing fences to channel vehicle traffic away from certain areas or prevent vehicular access into certain areas. When planning for fixed barriers such as these, several factors such as future site expansion and possible relocation of facilities and other structures should be taken into consideration. These types of activities may require fixed bollards to be excavated and reconstructed in other areas. Also, be careful not to place permanent barriers in areas where emergency response vehicles may need to gain access in the event of an attack or other emergency. Figure 4.22. Fixed Bollards.
