BS 812

Flakiness / Thickness Index Gauges measure particle shape of aggregates used in pavement base course applicationsor 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.

Stainless Steel Flakiness Index Gauges are heavy-gauge stainless steel with precision laser-cut openings and etched size markings for each slot. The aggregate to be classified is separated into seven sieve fractions from 6.3 to 63 mm, and each fraction is examined separately. Slot sizes are 4.9 x 30mm, 7.2 x 40mm, 10.2 x 50mm, 14.4 x 60mm, 19.7 x 80mm, 26.3 x 90mm and 33.9 x 100mm.
