Solution
1) -coarse grain( given that most of the material has a bigger size the #200
- since is 5.7%, is bewteen 5-12%, we need to use dual symbols.
SW-SM
sand well grained with claysof no plasticity
AASHTO
-Granular(given that 35% or less in this case 5.7% passed through sieve #200)
- GIVEN AASHTO
40 67% 51% min
20 5.7% 10% max
thereforeis A-3
general as a subgrade no plasticity
