Title: Intro to Stone Matrix Asphalt (SMA)
Speakers: Jon M. Young, Hawaii Asphalt Paving Industry
This session will introduce Stone Matrix Asphalt (SMA). SMA is a gap-graded hot mix asphalt (HMA) originally developed in Europe to maximize rutting resistance and durability. The mix design goal is to create stone-on-stone contact within the mixture. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly reduces rutting.
