Answer #1

CBR value can be calculated for subgrade in two conditions ;Soaked and unsoaked .For soaked CBR test soil sample is kept in water for 4 days and it represent least strength of subgrade . So from this CBR value we get maximum thickness of flexible pavement. Now see the solution. Hope it will help you. Feel free to ask any doubt in comment section. Thank you.
