Matest has developed an Automated Core Drill (ACD) for fast, accurate cutting of cores from
cylinders, prisms and slabs prepared using Matest’s range of asphalt compaction machines;
GYROTRONIC-Gyratory Compactor, ASC-Asphalt Shear-box Compactor and field specimens for
subsequent testing using Matest/Pavetest’s range of leading edge testing systems.

Adjustable specimen clamp eliminates specimen
movement during coring.
Three position fixture provides easy and accurate
specimen positioning.
Three core supports at fixed spacing yields two or
three cores from one prism.
Optional cylindrical specimen jig.
