Dynamic Analysis of Asphaltic-Aggregate Mixtures
Ultrasonic probes have been constructed for use in dynamic nondestructive testing of asphaltic concrete specimens.  Use of the probe systems was superior to use of
their main components alone, the piezoelectric crystals.  The probes have the advantages of reducing ringing time, concentrating...
