摘要：	In the spring of 1993 the Strategic Highway Research Program (SHRP) asphalt research program was completed. As the result of that effort a new specification for asphalt cements was developed along with new testing procedures. The results of a study of asphalts being used in the southeastern United States in which the asphalts were tested by using the current capillary tube testing technology and the new SHRP technology are presented. Fifty-eight asphalt cements from throughout the United States were tested. Viscosity of neat asphalt cements (60 deg C) showed strong correlations with dynamic shear rheometer stiffness at 60 deg C and 70 deg C. For the asphalt cements tested, the value of the slope of the log stiffness-versus-time curve obtained from regressed stiffness S-versus-m data from bending beam rheometer tests corresponding to an S value of 300 MPa was found to be 0.27.
