MoreFigure 4 indicates that all the RAP aggregates showed acceptable crushing values in the range of 25 to 28 percent. Comparing to the virgin/source aggregate from the same quarry source, the aggregate crushing values (ACV) are much lower, which implies that the virgin/source aggregate are more resistant to crushing effect.

MoreAn aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger. The specimen is then loaded via the plunger. The load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value (ACV).

MoreThis test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value. Granular sub-base is subjected to repeated loadings from truck types. The stress level at the contact points of aggregate particles is quite high.
