    Abstract
  • The characteristics of flexible-fiber-reinforced brittle materials were analyzed, and a mechanical model of single fiber pulled out from asphalt at low temperature was established.In spherical coordinate, a computation model of bridging stress for short fiber was established when short fibers uniformly distributed in asphalt, and the bridging stress was computed when asphalt ruptured.The bridging stress was measured by using tensile test and large size fiber asphalt samples at low temperature.The calculation model was corrected by fitting calculated and measured values of bridging stress.Analysis result shows that the maximal fitting error is 6.67%, so, the mechanics-experience method can be used to study the bridging stress of flexible short fiber at low temperature.
