1) GRAIN SIZE DISTRIBUTION ANALYSIS
The test is conducted in two stages: sieve analysis for coarse-grained soils (>0.075mm) and hydrometer analysis for fine-grained soils (< 0.075mm).
The results are presented by a grain size distribution curve which is combined as the percentage of sample smaller than, by weight, versus the log of the particle diameter. The curve provides the parameters about effective diameter (D60 & D10) and coefficient of uniformity (Cu). Tests were performed in accordance with ASTM D422.

2) ATTERBERG LIMITS TEST
|Atterberg limit test aimed to determine liquid limit (LL) and plastic limit (PL) which are very important indices used for classification of cohesive soil. The testing equipments are manufactured by HUMBOLDT – USA and procedures are according to ASTM, BS.|
