Aggregate Packing

The copper tailings were used at 20% content as a fine granite replacement for fraction size smaller than 118 mm The aggregate grading of the copper tailings mix was kept similar to the reference mix, thus the difference in aggregate packing between the two mixes was kept to a minimum In the same study, the effects of bitumen characteristics ....

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 ....
