AbstractStress-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 interlocking characteristics of the fibers were examined by a scanning electron microscope.
