The GCTS HWTT-100 Hamburg Wheel-Tracking Tester is used to test submerged, compacted Hot Mix or Warm Mix Asphalt specimens as per AASHTO T 324 standard.The device consists of a reciprocating wheel that is rolled over the specimens while measuring the rate of permanent deformation.

A constant load of 705 N ±4.5 N is applied to the specimens with a sinusoidal wheel speed of 1 ft/sec in a constant temperature controlled water bath up to 70 °C (± 1.0 °C). An LVDT jig is used for continuous measurement of permanent deformation along the path of the rolling wheel.

• Meets AASHTO T 324-04 standard

• Accommodates cylindrical or slab specimens

• Software for automatic determination of Stripping inflection Point(SIP), Number of passes to SIP, number of passes to failure Nf and other calculated parameters

• Stainless steel construction with temperature controlled water bath up to 70ºC

• Available Superpave Gyratory Compactor GRC-20 for specimen compaction
