This is the final report on a limited investigation comparing the performance of painted steel, galvanized steel and aluminum guardrails. A previous report was issued in 1964. The final inspection of the project was made in November 1969.
The project consisted of approximately 2500 lineal feet of each type of guardrail (see Figure 1 and Table 1). The painted steel and galvanized steel were installed in November 1962. The aluminum guardrails were installed in February 1963. All rails are the deep-beam type and were installed in accordance with special provisions which covered material requirements and erection procedures. The special provisions were included in the first report.
