Answer (1 of 2): Angular Aggregates are superior to rounded aggregates as; 1.Angular Aggregates exhibit a better interlocking effect in concrete, which property makes it superior in concrete used for roads & pavements.
With an increase in water-cement ratio the influence of roughness of surface of the aggregate gets reduced, presumably because the strength of the paste itself becomes paramount, and at a water-cement ratio of 0.65, no difference in strength of concrete made with angular aggregate on rounded aggregate has been observed.
Crushed bluestone item #4 is usually found in municipal driveways, though. The middle layer of a gravel driveway features stones closer to golf ball size, with #57 stone being the prominent type of gravel. Otherwise known simply as crushed gravel, #57 stone also helps promote drainage. 5 Types of The Best Surface Gravel for Driveaway

Crushed stone is defined as construction aggregate. A suitable rock formation is mined, then the rock is broken down into various sizes with a crusher. Gravel differs from crushed stone due to the natural process of erosion and weathering, and the rounded shape.
Crushed Gravel. Crushed gravel may look similar to crushed stone and fall into the same bracket of material, but the key difference between the two is that crushed gravel is not made by man. Crushed gravel comes in the same form that it’s found, there are no additives or other stones mixed in.
Aggregate is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. Aggregate may be natural, manufactured, or recycled. Aggregates make up some 60 -80% of the concrete mix. Fine Aggregate Vs Coarse Aggregate-
As such, gravel tends to be more rounded in shape. The modifier crushed specifies two things at once. First, that the aggregate be angular in shape and not rounded. Second, that the aggregate consist of a variety of sizes.
Crushed stone is available in a variety of sizes, from 3/8” to 4”. Because it is literally crushed stone, there is no consistency to its shape. The edges tend to be sharper and it feels rougher to the touch than pea gravel. Also, most crushed stone will either be in a white or gray hue, giving you a more neutral look than the colorful pea
Unlike crushed stone, gravel is usually sold and used in its natural state. If it is crushed, gravel loses its unique smooth rounded texture and becomes crushed stone. It is important to note that some contractors refer to any stone in certain size ranges as “gravel,” even if it is crushed stone.
Crushed And Uncrushed Aggregate. Crushed vs round aggregate in concrete structural feb 03 2012183 certainly crushed rock has better interlock and must have better shear friction for roughened surfaces i do not have the data but i would bet crushed rock is better in most or all performance measures
Everything I''ve ever poured contained crushed stone. Your selected text says that round aggregate has more effect on cements ability to flow than it''s strength. If the strength was the same & round stone/sand flows better, why do concrete companies use crushed stone? I also know that beach sand, very round, makes terrible concrete.
There is a general belief that crushed aggregates contribute higher strength in concreting compared to rounded aggregates. Contrary to this belief, our study revealed: rounded aggregates perform better than crushed aggregates because the rounded shape which considered as a negative characteristic is compensated by improving the workability and reducing the need of mixing water, thus; the water
