Rock Aggregates and Its Suitability | Geology

ADVERTISEMENTS: After reading this article you will learn about the rock aggregates and its suitability. Rocks can be crushed and graded to make aggregate which can be added to a bonding material like cement to form concrete, or bitumen to serve as a road stone. Various civil engineering works need different grades of aggregate. The [.]

Los Angeles Abrasion - Pavement Interactive

Overview. The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: L.A. abrasion testing equipment.
