    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.Factors Affecting Compaction Pavement Interactive,Gradation affects the way aggregate interlocks and thus the ease with which aggregate can be rearranged under roller loads. In general, aggregate effects on compaction can be broken down by aggregate size (TRB, 2000 [5]): Coarse aggregate. Surface texture, particle shape and the number of fractured faces can affect compaction.

  • The Effect of Aggregate Properties on Concrete

    Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.,
