If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.) If you use a jumping jack, about 20% would be accurate.

The factor of absence of defects refers to the degree of freedom from extraneous vegetable material, loose skin, broken and mashed beans, and blemished beans; or any other defects that may affect the appearance or eating quality of the product. (b) Definitions: (1) Loose skin means skin or portions of a skin which have become
Crushed stone is angular and rough. Crushed stone is more difficult to screen than natural stone. Flaky (thickness is small, relative to the other two dimensions) and elongated (length is larger than other two dimensions) stones are the most difficult to screen. They pass over the screen deck laying on their widest side.

C30 the compressive strength at 7 days of curing age is 31.52 MPa and at 28 days of curing age is 42.68 MPa. For C31, C32, C33 and C34 concretes, the compressive strengths at 7 days are 33.19, 34.21, 33.41 and 30.48 MPa (105.29%, 108.53%, 105.99% and 96.70% of C30), respectively.
Crushed rock is one of the most accessible natural resources and a major basic raw material. It is used in construction, agriculture, and other industries using complex chemical and metallurgical processes. Despite the low value of its basic products, the crushed rock industry is a major contributor to and an indicator of the economic well
