OBS

aggregate activity: term and definition proposed by the World Road Association.

French

Domaine(s)
  • Matériaux de constr. (Voies de circulation)

Record 2 2011-09-27

English

Subject field(s)
  • Rheology
  • Soil Mechanics (Engineering)
DEF

The numerical difference between the water content at the liquid limit and the water content at the plastic limit of a soil.

OBS

The plasticity index... indicates the range in moisture content over which a soil remains in a plastic state prior to changing into a liquid.

OBS

plasticity index : term officially approved by the Engineering Terminology Working Group(ETWG).

Key term(s)
  • index of plasticity

French

Domaine(s)
  • Rhéologie
  • Mécanique des sols
DEF

Différence exprimée en pourcentage entre l'humidité relative d'un sol à la limite des états liquide et plastique.

CONT

L'indice de plasticité (IP) est la différence entre la limite de liquidité et la limite de plasticité. [...] Un sol ayant un indice de plasticité élevé aura [...] une importante variation de volume lorsqu'il passera de la limite de plasticité à la limite de liquidité.

OBS

indice de plasticité : terme et définition uniformisés par le Groupe de travail de terminologie du génie (GTTG).

Record 3 2010-06-10

English

Subject field(s)
  • Soil Mechanics (Engineering)
  • Soil Science
DEF

The ratio of the difference between the nature soil water content and plastic limit to the soil plastic index (PI) of the same soil.

CONT

The liquidity index(LI) is used for scaling the natural water content of a soil sample to the limits. It can be calculated as a ratio of difference between natural water content, plastic limit, and plasticity index : LI=(W-PL)/(LL-PL) where W is the natural water content.

OBS

liquidity index: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Mécanique des sols
  • Science du sol
CONT

Sur la base des limites de liquidité et de plasticité et en connaissant la teneur en eau naturelle du sol w on peut définir d'autres indices qui sont utilisés en mécanique des sols. Ce sont en particulier, l'indice de liquidité [...] qui est défini par la relation: IL = (w - wP)/IP et l'indice de consistance [...] qui est défini par la relation: IC = (wL - w)/IP

OBS

Record 4 1993-07-22

English

Subject field(s)

DEF

For natural rubber, the ratio of the plasticity number measured after an air oven ageing, under specified conditions, to the plasticity number measured before ageing.

French

Domaine(s)
  • Caoutchouc
DEF

Pour le caoutchouc naturel, rapport de l'indice de plasticité mesuré après vieillissement en étuve à air dans des conditions spécifiées, à l'indice de plasticité mesuré avant vieillissement.
