Term of the Road Dictionary

complex modulus

  • Language : PIARC Road Dictionary / English
  • Theme : Roads Materials Mixed Materials
  • Definition : Modulus characterizing the recoverable deformation behaviour of linear viscoelastic materials under harmonic stress. Notes: 1. It is a complex number which is the ratio of complex stress to complex strain. 2. This quantity is used to characterize the recoverable deformation behaviour of bituminous mixtures at low stress amplitude.

komplexer Modul

  • Language : PIARC Road Dictionary / German
  • Theme : Straßen Baustoffe Gemischtes Material
  • Definition : Modul, der das sich elastisch rückstellende Verformungsverhalten von linear viskosem Material unter harmonischer Beanspruchung beschreibt. Es ist eine komplexe Zahl, die das Verhältnis zwischen komplexer Spannung zur komplexen Dehnung darstellt. Die Größe wird verwendet, um das sich elastisch rückstellende Verformungsverhalten von bituminösem Mischgut unter kleinen Spannungsamplituden zu beschreiben.
