This standard specifies a method for determining the 10% fines aggregate crushing value (FACT value) of a coarse aggregate sample. The FACT value is measured by crushing the aggregate sample and determining the force required to produce 10% fines, which are particles that pass through a 2,360 micrometer sieve. The test can be performed in either dry or wet …
The objectives of the tests is to determine the aggregates impact value (AIV) of aggregate. THEORETICAL BACKGROUND. Aggregates play an important role in the design and constructionof highway and air- field pavements. They are also major part of rigid (concrete) andflexible (asphalt) pavements.
