Road stones should be tough enough to resist fracture under impact. Polished stone value test is to determine how quickly a sample of aggregate will become 'polished', worn smooth, by the repeated passing of tyres. The higher the polished stone value the longer the aggregate will remain rough when used in road surfacing.
· Aggregate crushing Value =(W B /W A) × 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety Precautions: Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes helmet during the time of test. Before testing, machine should be checked. After test ...
· This percentage is known as a crushing value of aggregate. This percentage should not exceed 30% of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%.
Then crushed aggregates are then sieved through mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.
· Science friction: testing fine aggregates in asphalt and concrete. 10th March 2015. The Ontario Ministry of Transportation has developed significant expertise in assessing the frictional qualities of coarse aggregate in hot mix asphalt pavement.

DETERMINATION OF AGGREGATE CRUSHING VALUE. 1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
Therefore, lower abrasion loss values indie aggregate that is tougher and more resistant to abrasion. Figure 7: Steel spheres. Test Adequacy. The Abrasion test is an empirical test; it is not directly related to field performance of aggregates. Field observations generally do not show a good relationship between abrasion values and field performance. Wu et al. (1998 [2 ...
