Design the concrete mix of materials
AC Mix
in road and highway construction

• Design objectives : Develop an economical blend of aggregates and asphalt that meet
design requirements

• The two most common traditional methods for making and evaluating trial mixes have
been:
i. The Marshall method : use impact hammer
ii. The Hveem method : use kneading compactor

iii. New method (Superpave gyratory) : use gyratory compactor to simulate field

compaction, able to accommodate large size aggregate (Developed by the Strategic
Highway Research Program (SHRP) )
