  • A value of Cu greater than 4 for gravels and 6 for sand classifies the soil as well graded. ( According to USCS, Unified Soil Classification System)
  • When Cu is less than 4, it is classified as poorly graded or uniformly graded soil.
  • Uniformly graded soil has identical particles with Cu value approximately equal to 1 also called one grain size.
  • A uniformity coefficient value of 2 or 3 classifies the soil as poorly graded.
