Weighted value from the rough aggregate angular index, Yi may be the
Weighted value of your rough aggregate angular index, Yi is the angularity index on the i-th particle in the aggregate sample, and Ai is definitely the area from the particle from a leading own view.oatings 2021, 11, x FOR PEER REVIEWCoatings 2021, 11, 1321 four oftings 2021, 11, x FOR PEER REVIEWFigure 1.

The abrasion test was carried out based on the coarse aggregate abrasion test of Highway Engi1.070 neering Aggregate Test Specification (JTG E42-2005, Highway Study Institute with the 9.5 abrasion outcomes are shown in Figure 2.

The cause for this result is the fact that of eachas the quantity of wear aggregate progressively decreases.the coarse aggregate surface are that particle size within the increases, the edges and corners on the cause for this outcome is because the quantity of put on increases, the edges and corners of the coarse aggregate surface are progressively worn away, generating the aggregate increasingly smooth. At the identical time, when progressively worn away, making theabrasion because the boundary, the large-diametersame time, when considering 500 Tenidap site repetitions of aggregate increasingly smooth.
