Crushing process encompass some modification to match the demand for each type of gradation [4]. Generally, crushed rock is one of the unbound granular materials (UGMs) that used
Shifting in the gradation curve is basically caused by the formation of smaller particles during grain crushing. As a result, a material changes its state from a poorly graded to a well-graded state as evident from various other studies where a significant change in the gradation curve before and after crushing is observed [25], [57].
Double-plate grain crushing tests were carried out on dolomite, calcerous, and basalt origin grains, having sizes ranging from 2.00 to 37.50 mm. Factors affecting the single grain crushing ...
The gradation curve of the spherical particle is on the far right except for the original gradation curve. This phenomenon can be explained by the fact that the single-particle crushing test is terminated when the spherical particle is broken into three or four parts, so the ranges of the gradation are relatively narrow.

As shown in Fig. 3, corresponding to the PDF, the gradation curves in the semi-logarithmic coordinate system (D i /D max) 0.45-P i were classified into three types: Progressive-Y type (Type 1), S type (Type 2) and Progressive-X type (Type 3), and the shape of the gradation curve was transformed from Type 1 to Type 2 and then to Type …
The relationship between the microcracks of a single particle and the crushing strength was studied by virtual experiments. The three-dimensional profile of a single particle was obtained by CT-scanning technology. The particle bonding model is used to fill the three-dimensional contour to construct virtual particles, and the virtual …
this research is to compare the deformation response of Class 2 basalt and granite crushed rocks as an approach to characterise Class 2 according to their mechanical behaviour.
This study investigates the physical properties of gravel, such as dry density, void ratio, and relative crushing index, under different initial gradations (uniformity …
Incomplete data indicate that coal gangue is accumulated in China, with over 2000 gangue hills covering an area exceeding 200,000 mu and an annual growth rate surpassing 800 million tons. This accumulation not only signifies a substantial waste of resources but also poses a significant danger to the environment. Utilizing coal gangue …

Furthermore, an S-shaped curve is preferable for the gradation curves [23,25]. Thus, the family of gradation curves were designed by adjusting the passing rate of BSS in S-shaped curves. Seven gradation curves were numbered gradations 1–7 according to the passing rate of BSS, from the largest to the smallest, as shown in Table …
The results from the RLTT test shows that Class 2 crushed basalt rock has PD varied from 2.0% to 4.3 % while PD of Class 2 crushed granite rock varied from 1.0% to 2.3% meaning that granite rocks...

In this curve, the cumulative percentage of material passing down is plotted inordinate, and the size of the sieve opening is plotted in abscissa which is a logarithmic scale. Types of aggregates on basis of gradation curve 1) Uniformly graded Aggregates. This refers to the sample which consists of a particular size of aggregates predominately.
A gradation that, when plotted on the 0.45 power gradation graph, falls mostly above the 0.45 power maximum density line. The term generally applies to dense graded aggregate. Coarse gradation. A gradation that, when plotted on the 0.45 power gradation graph, falls mostly below the 0.45 power maximum density line.
As seen in table the mixture consists of 50% coarse aggregate and 50% fine aggregate in weight. The selected aggregate gradation was in accordance with the General Directory of Turkish Highway (GDTH) recommended gradation for granular base layers.
A gradation-dependent hypoplastic model is developed to capture the mechanical behaviours of crushable sands. First, a gradation evolution law is proposed to describe the variation of the grain size distribution (GSD) and the development of the extent of crushing during the loading process.
