Mention two desirable characteristics of aggregate shape ref

-Mention two desirable characteristics of aggregate shape? (refer to http://www.pavementinteractive.org/particle-shape-and-surface-texture/)

-What term would be given to an aggregate having length and width dimensions approximately equal, but six times larger than particle thickness? (refer to http://www.pavementinteractive.org/flat-and-elongated-particles/

-If you measure the bulk and apparent specific gravities of an aggregate sample, which one should be higher and why? (http://www.pavementinteractive.org/aggregate-weight-volume-relationships-and-terms/)

Solution

- Two desirable characteristics are workablity and good interlocking capacity.

- If length is equal to width then it is called flat aggregate.

- Bulk specific gravity yields more value because bulk means it include unit weight of water+dy soil.
