Dept. of TransportationRoque, ReynaldoUniversity of FloridaUS Transportation CollectionSuperpave is a set of methods and materials for asphalt paving and the primary methodused by the Florida Department of Transportation. It is well documented that performanceof asphalt mixtures is strongly affected by size composition of aggregate, which makes upbetween 80 and 90 percent by volumeof hot asphalt mix. Asphalt mixes thatperform well in laboratory rutting testsmay not have acceptable crackingperformance in the field. The sizecomposition of aggregate presents anopportunity to improve cracking behaviorof asphalt pavements
