Flexible pavements are those, which on the entire have low or immaterial flexural quality and are somewhat Flexible in their basic activity under the loads. The Flexible pavements layer reflects the distortion of the lower layers on – to the surface of the layer. Accordingly, if the lower layer of the pavements or soil subgrade is undulated, the adaptable parts: 1)soil subgrade 2) sub-base course 3) base course furthermore, 4) surface course.
The Flexible pavements layers transmit the vertical or compressive worries to the lower level by grain to grain exchange through the purpose of contact in the granular structure. A very much compacted granular structure comprising of the solid evaluated total can exchange the compressive worries through a more extensive territory and therefore frames a decent Flexible pavement. The load spreading capacity of this layer hence relies upon the kind of the material and the blend configuration factor. The Bituminous cement is one of the best Flexible pavement layer materials. Flexible pavements the regularly outlined utilizing exact outlined graph or condition taking into account a portion of the outline factor. There are too semi observational and hypothetical plan strategy.
