Thecrushing value testis conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously. So the aggregate used for road construction should be able to sustain that motion pressure.
