Influence of Aggregate Morphology and Grading on the

Stone matrix asphalt (SMA) is a gap-graded hot mix asphalt with a high percentage of coarse aggregate and a high asphalt content. SMA is the typical gap-graded mixture used in Virginia that is intended to maximize rutting resistance and durability with a stable stone-on-stone skeleton held together by a rich mixture of asphalt binder.

Effect of Coarse Aggregate Angularity on Rutting

Permanent deformation (rutting) is one of the major distresses in hot-mix asphalt (HMA) pavements. Coarse aggregate angularity (CAA) has an important effect on the rutting characteristics of HMA. More angular coarse aggregates can increase the stone-on-stone interlocking and consequently reduce the rut-susceptibility of mixtures.

Effect of Coarse Aggregate Angularity on Rutting

Permanent deformation (rutting) is one of the major distresses in hot-mix asphalt (HMA) pavements. Coarse aggregate angularity (CAA) has an important effect on the rutting characteristics of HMA. More angular coarse aggregates can increase the stone-on-stone interlocking and consequently reduce the rut-susceptibility of mixtures.

has formed. Rutting and moisture-induced dam-age are not only dependent on the asphalt content but on the characteristics of the aggregates in the mixture as well, and thus a proper selection of aggregates can reduce rutting and moisture-induced damage to HMA. For example, rutting can be reduced by the use of large aggregates,

F. Allowable Rutting (RD) in Surface Layer Rutting is bound to occur in aggregate surfaced road,and is considered as performance criteria. If the rut is too high, then it is very difficult to drive on the road surface due to the creation of channels along wheel paths. This rutting will ultimately lead the road into permanent deterioration.
