• Description:
  An ADIEM II (Advanced Dynamic Impact Extension Module) was installed on Interstate 5 near Salem, Oregon. This device was used for an end treatment because of space limitations imposed by the steep fill. A three-person crew completed installation in about two hours.
  
  Because the installer did not have the proper lifting equipment, the installation was delayed while a heavy-duty forklift was transported to the job site. No other major problems developed.
  
  The bases of the crushable concrete modules were not sealed with paint as effectively as the rest of the module. Moisture could penetrate the porous concrete from the bottom up. This area will be watched closely during the next three-year evaluation period. The blocks are easy to move if additional sealing is necessary.
