Oven dry it at 105 to 110 0 C. … WebIf the soil has 5–12% by weight of fines passing a #200 sieve (5% < P #200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt.". If the soil has more than 15% by weight …
Webas a jaw-crusher is ideal for this purpose. For very high clay soils, sieving prior to oven drying may be desirable to facilitate efficient sieving. In this case, both the > and < 2 mm material must be air dried after sieving prior to recording their respective masses. A flowchart of sample processing is provided in Figure A1.1. Bulk density.
