Application Of Aggregat Crushing Test

LA Abrasion Test: Aggregate Abrasion Testing Pt 2
Abrasion testing determines the relative quality, toughness, and durability of mineral aggregates subjected to impact and abrasion. Values derived from both the Micro Deval and the Abrasion tests offer information about the performance of aggregate in use. This testing offers insight into how asphalt and concrete aggregates will stand up to wear and tear over time. It's also a good ...
