The selection of proper aggregate for a given application is essential to attain the desired quality. Various characteristics are required to be determined for the selection of appropriate aggregate from the wide range available. Aggregate crushing value test apparatus is used for measuring resistance of an aggregate to crushing.Los Angeles (L.A.) Abrasion Test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA (Hot Mix Asphalt) samples should resist crushing, degradation and disintegration in order to produce a high-quality HMA.Laboratory jaws crusher a061n high capacity sieve shaker high end laboratory ovens. forced ventilation, digital thermostat high temperature uniformity up to 300 c a023-01n muffle furnace 1100 c high capacity a023-01n bar (grid) sieves aggregate flakiness index and particle shape a068 large capacity sample splitter.Crushing With Posimetric The selection process is largely based on experience and testing — experience with actual field applications and laboratory tests that show how a given material will be reduced by a given crusher type. The main purpose of this handbook is to explain the.
