crushing value of aggregate - AnnaSweetHome - Home

For an aggregate to perform satisfactory in pavement, it must be sufficiently hard to resist the abrasive effect of traffic over long period of time. The soft aggregates will be quickly ground to dust, whilst the hard aggregates are quite resistant to crushing effect. The test also will determine the quality of the aggregate.
