Aggregates with lower crushing value show a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance. If we used a weaker would get crushed under traffic loads, would produce smaller pieces not coated with a binder, and these would be easily displaced or loosened out resulting in loss of the surface/layer.

After the first crushing stage, it can be seen from Table 2 that crusher 2 (with worn jaws, setting 22 mm) produces aggregates with the lowest FI and at the second stage crusher 4 lowers the FI the most. If the crushing at laboratory 3 was performed only with crusher 3, the FI might also be very high. The improvement of the shape properties of aggregates that have been crushed with crushers 1
