This book describes the key factors of particle morphology quantification and its characteristics that govern the interparticle behaviour of granular soils. A standardised and cost effective method of quantifying particle shape parameters has not been widely recognised yet, therefore the methods are still being debated today. In this booklet, explanation of a new approach of particle shape classification was presented. Cluster and statistical analysis was used to find a single representative value of the particle shape parameters from 5 different sand samples. With that, the behaviour of the...
