Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The work presents the first discrete element method (DEM) simulations of dynamic compaction in the Proctor test. The aim of the simulations was to analyze the influence of particle breakage on the density of intensely compacted granular assembly. Results from simulations and laboratory tests were compared. Simulations with non-breakable aggregates enabled separation of the influence of change in particle size distribution and particle rearrangement. Both factors play an essential role in increasing the bulk density of the sample in the case of the tested (gap-graded) aggregate. Simulations with breakable particles reproduce the laboratory tests results better, both qualitatively and quantitatively. The conclusions provide a better understanding of the aggregate compaction process, which is crucial for developing novel compaction strategies and minimizing the environmental impact of the construction process.
