Full Description

AASHTO PP 104-20 covers the sample preparation and polishing of asphalt mixtures for dynamic friction testing using a three-wheel polishing device (TWPD). This standard is to be used with compacted asphalt mixture slab specimens. Other specimen preparation procedures would be needed for assembling a group of gyratory cylinders to be polished using a TWPD.
