Binder Course; Wearing Course (It is the layer which is in direct contact with the tyres of the vehicle) Functions of Surfacing of Road: Prevent penetration of water in to the pavement ; Binder Course binds the Wearing Course with the Road Base; Wearing
Typical Road Structure Cross Section Sub Grade, Base
It acts as a separating layer b/w subgrade and road base. By this it prevent the two layers from mixing up. b. Characteristics of materials used in Sub Base: The subgrade material should be clean and free from organic matter and should be able to be compacted by roller, to form stable sub-base. The material should have following characteristic. Well graded uniformity coefficient (D60/D10

This is the lowest layer of the road construction, and is made of cement bound granular material containing crushed rock or gravel. This is the road foundation and it transfers the loads from above to lower layers, building up the strength of the road pavement. Capping Course.

What are Different Layers in a Bituminous Pavement?
It is the first layer in case of two-layer bituminous resurfacing. Bituminous binder course is made of bituminous-aggregate mixture, also called as levelling course. 3. Bituminous Concrete Layer. Bituminous concrete layer is a mixture of aggregates continuously graded from maximum size to minimum sizes (typically less than 25mm to 0.075mm
Subbase (pavement) Wikipedia
In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles. Subbase is often the main load-bearing layer of the pavement.Its role is to spread the load evenly over the subgrade.
Vitruvius described the process of Roman road construction:
The upper layers of the road are always laid carefully, "of finer material well-rammed down" possibly in several, successive layers. The road surface itself consists of layers of finer material with a total thickness of between 2-3in (5-7.5cm) and 1-2ft (30-60cm). Additional layers are added by re-surfacings. The total depth of a road, from surface to the bottom of the base, could reach 1 to 1

CHAPTER 3 ROAD DESIGN
An improvement over a simple dirt road consists of a ballast layer over a subgrade, with or without a wearing course. The function of the ballast layer is to distribute the wheel load to pressures the subsoil can withstand. The wearing course provides a smooth running surface and also seals the surface to protect the subgrade from surface water infiltration. The wearing course can either be a
