Unformatted text preview: This was used to determine that the soil was well-graded sand with gravel (ASTM symbol SW). For the third problem we were given an article to read about the particle size distribution of lunar soil. It was stated in the article that the lunar soil is classified as sandy silt/silty sand and also well-graded. It was also stated that the lunar soil had a coefficient of uniformity approximately equal to 16. Hence, the lunar soil may be internally erodible, that is, it is potentially susceptible to “segregation piping”. Therefore, I would not allow the lunar soil to be used as structural fill.
