Understanding Effects of Crushing Mechanism on Aggregate Morphology Using AIMS
The present study compared angularity, texture, sphericity and flat and elongation (F&E) ratio of three different sizes (P19-R12.5, P12.5-R9.5 and P9.5-R4.75) of coarse aggregate produced from two different types of crushing operations. The aggregates were collected from two different types of crushers: (i) the first crusher had jaw, cone and vertical shaft impactor (VSI) as primary, secondary and tertiary crushers, respectively; and (ii) the second crusher had jaw, horizontal shaft impactor (HSI) primary and secondary crushing unit, respectively. The angularity, texture, sphericity and flat and elongation (F&E) of aggregates were measured using aggregate image measurement system (AIMS) in accordance with the AASHTO TP81 method. Further, laboratory tests like angle of repose (AoR) and VCAdrc were conducted to identify the influence of aggregate morphology on the performance of aggregates. The results showed that aggregates produced from JH series of crusher had higher F&E ratio, higher texture and lower sphericity as compared to aggregates from JCV series of crusher. However, both the crushers JH and JCV produced aggregates with similar angularity. The aggregates produced from JH series of crusher show better performance over JCV produced aggregates.
