  • Unified Soil Classification System Wikipedia

    The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain size distr

    terms cobbles, gravel, sand, and fines (silt or clay) are used to designate the size ranges of soil particles. The gravel and sand ranges are further subdivided into the groups as presented in Table B-1. The limiting boundaries between the various size ranges have been arbitrarily set at certain US standard sieve sizes as listed in Table B-1

    Dec 24, 2016· The formal definition of Class 5 Gravel is limestone rock crushed and screened to a maximum size of 1 inch. In the UP of Michigan there are variations of class 5: the two most common are “23A” and “Western Limestone.” What distinguishes the two types is the “binder” that is used that allows the gravel to be compacted.

    To determine a soil’s classification in the AASHTO system, one first determines the relative proportions of gravel, coarse sand, fine sand, and silt-clay. In the AASHTO system gravel is material smaller than 75 mm (3 in.) but retained on a No. 10 sieve; coarse sand is material passing a No. 10 sieve but retained on a No. 40 sieve; and fine
