N2  - Presented here are the results of a research and compliance testing program to develop a low-cost, high-performance terminal for portable concrete barriers (PCBs) and permanent concrete median barriers (CMBs). The result is the Advanced Dynamic Impact Extension Module (ADIEM). The energy absorption elements of this terminal are lightly reinforced, ultra-low-strength Perlite concrete modules. The redirection element of this terminal is a heavily reinforced conventional concrete variable height curb with automobile hub-height pipe rail. ADIEM meets the requirements in NCHRP Report 230 at a cost of approximately $100/ft. This translates into a projected cost for a 60-mph class, 30-ft barrier of $3,000. This appears to represent a major cost reduction for high-performance PCB and CMB terminals. ADIEM is also expected to find wide application in protecting vehicle occupants from such other roadside obstacles as utility poles.
