Advanced Dynamic Impact Extension Module 350 (ADIEM 350)
Purpose: The ADIEM 350 is an end treatment for concrete barrier. At this time, it is limited to temporary installations. Existing permanent installations are experimental and are being used to evaluate long-term durability. Existing permanent units may be reset.
Description: The system is 30 feet
long and consists of 10 lightweight concrete modules on an inclined base.
Functionality: An inclined base provides a track for placement of the modules and provides redirection for side impacts for roughly half the length. The energy of an impact is dissipated as the concrete modules are crushed.
Foundation: The system does not require a paved foundation.
Slope: If the site has excessive grade or cross slope, additional site preparation or modification to the units in accordance with the manufacturer's literature is required. Excessive is defined as steeper than 8% for the ADIEM 350.
