The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material.In hma, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility roberts et.

Contentstypes of pavementsflexible pavementsrigid pavementsdifference between flexible pavements and rigid pavements types of pavements there are two types of pavements based on design considerations i.Flexible pavement and rigid pavement.Difference between flexible and rigid pavements is based on the manner in which the loads are distributed to the subgrade.
Pioneer road location at bottom of proposed fill provides a bench for holding fill material of completed road.2 general equipment considerations.The method and equipment used in road construction is an important economic and design factor in road location and subsequent design.
Road construction techniques gradually improved by the study of road traffic, stone thickness, road alignment, and slope gradients.Initial road construction materials were stones that were laid in a regular, compact design, and covered with smaller stones to produce a solid layer.
The thckness design of the pavement is the determination of the overall thickness of the road and the thickness of the individual layers.This is of course dependant on the type of material chosen for the road.This is explained in more detail below.The procedure described in this page is that in the design manual for roads and bridges, volume 7.
