AASHTO: AASHTO Soil Classification (AASHTO Group Classification)

Description

Classifies soil using the American Association of State Highway and Transportation Officials (AASHTO) Soil Classification System. Inorganic soil classification using the AASHTO method. 1 December 2015

Usage

AASHTO(
  sieve = NA,
  size = NA,
  percent = NA,
  metric = NA,
  p10 = NA,
  p40 = NA,
  p200 = NA,
  LL = NA,
  PL = NA,
  PI = NA,
  NP = NA
)

Value

AASHTO group classification

Arguments

sieve: = vector of sieve numbers (according to ASTM D422) in grain-size distribution [Grain-size parameter]
size: = vector of grain sizes (in or mm) in distribution [Grain-size parameter]
percent: = vector of percent passing in grain-size distribution [Grain-size parameter]
metric: = logical variable for grain-size distribution: TRUE for metric units (mm), FALSE for English units (in); only required if "size" is supplied [Grain-size parameter]
p10: = percent passing #10 sieve [Grain-size parameter]
p40: = percent passing #40 sieve [Grain-size parameter]
p200: = percent passing #200 sieve [Grain-size parameter]
LL: = liquid limit (percent) [Plasticity parameter]
PL: = plastic limit (percent) [Plasticity parameter]
PI: = plasticity index (percent) [Plasticity parameter]
NP: = logical variable indicating whether the soil is nonplastic (TRUE or FALSE) [Plasticity parameter]
