Stress-strain properties of Type 15 asphalt-saturated, organic, and asbestos felts are compared at room temperature and 50 percent relative humidity. The rate of water sorption by asphalt-saturated organic felt immersed for 520 h in distilled water at room temperature and the effect of moisture on its strength characteristics are assessed. The structure of unsaturated organic felt and the inter-locking characteristics of the fibers were examined by a scanning electron miscroscope.
