Term of the Road Dictionary

resilient modulus

  • Language : PIARC Road Dictionary / English
  • Theme : Roads Materials Soils and Aggregates
  • Definition : Modulus characterizing the recoverable deformation behaviour of unbound granular materials. Note: in a repetitive loading triaxial test under constant lateral stress, it is the secant modulus at unloading calculated as the ratio of the stress deviator to the axial recoverable strain.

Elastizitätsmodul1

  • Language : PIARC Road Dictionary / German
  • Theme : Straßen Baustoffe Erdreich und Gesteinskörnung
  • Definition : Modul, der das sich elastisch rückstellende Verformungsverhalten von ungebundenem körnigem Material beschreibt. In einem Triaxialtest mit wiederholter Belastung unter konstanter Seitenspannung ist es der Sekantenmodul, der im unbelasteten Zustand aus dem Verhältnis zwischen der Spannungsabweichung zur axial sich elastisch rückstellenden Dehnung berechnet wird.
