a) AASHTO Classification :- Given percent passing No. 200 seive = 41 41>35% Then + General classification = Silt-clay minerals " percent passing No. 40 seive = 64 Liquid limit - 31 440 Plasticity Index = 12711 from AASHTO classification system, for A-6 group, clancy soil liquid limit - 40 minimum plasticity inden= 11 minimumm So, the given soil is, Үсыр – 46 хор significant constituent matewal - clayey soils rating as subgrade - fair to poor
