For aggregates smaller than 10 mm a 75 mm diameter cylinder and associated equipment is available UTA and UTA Test Sets are also used for the Ten Percent Fines Value TFV of aggregates according to BS 812 111 The Aggregate CrushingAggregates with lower crushing value shows 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 binder and these would be easily displaced or loosened out resulting in loss of the surface / layer

But in thecase of fine grained highly siliceous aggregate which are less resistant to impact than to crushing theaggregate impact values are higher on the average by about 5 than the agg1egate crushing valu 16/3/ 32 Therefore the road aggregates should be hard enough to resist abrasion Resistance to abrasion of aggregate is determined in laboratory by Los Angeles test machine The principal of Los Angeles abrasion test is to produce abrasive action by use of standard steel balls which when mixed with aggregates and rotated in a drum for specific number of revolutions also causes impact on aggregat
