General comments (publicly viewable) (Max 1000 characters): The presence 1½″ particles in a relatively small sample could cause the percentage of the sample reported passing the coarser sieves to not accurately represent the general population. A few additional or missing large stones can shift the entire gradation up or down proportionately.
