The Thickness Gauge (INDOT - Indiana) measures particle shape of aggregates used in pavement base course applications or asphalt and concrete paving mixes. It can also determine application rates of aggregate and asphalt material for pavement seal coats. The presence of flaky particles is undesirable and increases the possibility of pavement break-down under heavy loads.
The Thickness Gauge (INDOT - Indiana) is made from heavy-gauge stainless steel with precision laser-cut openings and etched size markings for each slot.
The Thickness Gauge (INDOT - Indiana) meets Indiana Department of Transportation standard ITM No. 224-18T and has five slots for manual checking of particles. Openings range from 0.25 to 1in (6.35 to 25.4mm).
Features:
- Laser-cut heavy-gauge stainless steel for superior accuracy and service life
