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)
