Gradation and Size

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

2. POROSITY

Real rocks contain a distribution of grain sizes, and often the grain size distribution is multi-modal. The best way of understanding the effect is to consider the variable admixture of grains of two sizes. (Figure 2.4).

Alice, aggregates and tax: muddy waters

Materials consisting of both clays and silts (grain sizes in the range from 4 to 62.5 μm) are generally referred to as 'muds' or as being 'argillaceous'. Geotechnical engineers commonly differentiate between silts and clays on the basis of their plasticity, as measured by their Atterberg Limits, rather than by any precise grain size.
