This program was to obtain data as to what degree solar radiation affected the breaking strength of webbings exposed to natural weather. Four groups of webbings were evaluated for breaking strength after being exposed to natural weather for specific time intervals encompassing one year. The exposure sites were Wright-Patterson Air Force Base, Ohio; Las Cruces, New Mexico; and College, Alaska.

Data obtained indicate that the service life of the present type of runway barriers can bee increased to 180 days in areas of extremely strong sunlight and to 360 days in areas of moderate or small amounts of sunlight by either one of the following two methods:

1. By using 260 denier 17 filament, Type 300, OD color nylon yarn in the manufacture of the webbing.

2. By using Type 330 nylon yarn in the manufacture of the webbing.
