Abstract:
1. A method of fabricating a vehicle arresting unit for vehicle arrestment, comprising the steps of: (a) providing a block of compressible material having top, bottom and side surfaces, said block having compressive failure characteristics selected to decelerate a vehicle with deceleration limited to avoid vehicle damage during arrestment; (b) positioning intermediate material above said top surface, said intermediate material having a force transmission mitigation characteristic and comprising material different from the compressible material; and (c) positioning frangible material above said intermediate material, said frangible material fabricated to protect said block and intermediate material prior to vehicle arrestment and said frangible material having a breaking strength to readily break without subverting said compressive failure characteristics and comprising material different from the compressible material and the frangible material.
