An Image-Based Gradation Calculation Method considering Crushed
An image-based gradation calculation method considering crushed stone morphology is proposed in this paper. Eight kinds of crushed stones are prepared to So, the reasonable gradation is essential to improve the strength and stability of graded crushed stone. Based on the material optimization design method, it is an effective way to improve the road Research on Design Indicators for Graded Crushed

Permeability Properties of Crushed Stone
Crushed stone is the most common material for use in the aggregate of bedding course. The aggregate for the bedding course of permeable roads needs to not only meet the requirements of basic Crushed Gravel #2: Approx 1½ ″ to 3″ Wide. Crushed rocks in grade no. 2 usually range from 1½ inches to 3 inches in diameter, so, depending on your supplier, may contain larger gravel stones that, like #1, are not easy to work with and will need to be moved as individual pieces. Uses of gravel #2 include the following:Gravel Size Chart, Crushed Stone And Rock Sizes, Uses, Grades

Two types of materials, crushed limestone and crushed gravel, were used and labeled as C and G, respectively, for the sample designations. For example, C-CA6-A refers to a sample that is crushed limestone with CA 6 gradation, 5% PI, 0.4 DR, 5% FC (see Fig. 2). In this figure “X” symbol indicates the tests that were conducted.Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.The Complete Guide to Crushed Stone and Gravel Gra-Rock

2.4.2. Atterberg Limits. The Atterberg limits are a basic measure of the nature of a fine-grained soil.Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties.Poorly-graded gravels and gravel-sand mixtures; little or no fines.
