This question actually needs very long & detailed answer,It can not be answered in 2 lines.However,Let me summarize this as possible.
- The flexible pavement contains 4 main pavement layers that are as following Sub-grade(Natural soil) , Sub-base , base & Surface Course.
- The surface course contains 4 layers as well that are as following Prime Coat , Binder Course , Tack Coat & Wearing Surface.
- The Binder Course & Wearing Course contains the Following (Coarse aggregate + Fine aggregate + mineral filler + Asphalt)
- Size & Gradation of aggregate(Coarse & fine) shall be as following as per AASHTO …> Coarse aggregate (Retained on Sieves#4 , 8 & 10) …> and the fine aggregate (Passing from Sieves#4 , 8 & 10) …> Mineral filler (at least 70% pass from sieve#200)
- Regarding the Subgrade soil shall be Fine or Coarse aggregate and the soil shall have group index less than 4 to be suitable for use as per AASHTO
- Group index equation as following (G.I=0.2*a + 0.005*a*c + 0.01*b*d)

Basically in soil there is 3 part Solids partical Air Water When water added to soil, at that time soil become saturated. And when air contain replace by water and soil become fully saturated at that time soil have two part one is water and one is solid partical. If we add more water than fulRead more
Basically in soil there is 3 part
When water added to soil, at that time soil become saturated. And when air contain replace by water and soil become fully saturated at that time soil have two part one is water and one is solid partical.
If we add more water than fully saturation, hence saturation of soil is 100% or more than that, is called the supersaturated stage.
Water content more than shrinkage limit called supersaturated stage
