The Thickness Gauge (Flakiness Index) 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 The Thickness Gauge (Flakiness Index) is made from heavy-gauge stainless steel with precision laser-cut openings and etched size markings for each slot.
The Thickness Gauge (Flakiness Index) meets BS-812 specifications and features seven slots for rapid hand trying of particles from each of the seven sieve fractions from 2.5 to 0.25in (63 to 6.3mm). The mass of all flaky particles as a percent of the whole sample is the flakiness index.
Features:
- Laser-cut heavy-gauge stainless steel for superior accuracy and service life
- Laser-etched markings clearly label each slot
