The report submitted herewith pertains to an experimental installation of aluminum guardrails which was completed in February, 1963. Progress reports, as required by PPM's 60-2 and 50-1.1, have been pending since the project began; however, all of the eligible information has been combined into the current report. Of course, long-time performance histories cannot yet be documented; and, for that reason, the report is considered to be interim rather than final.
