Weight of the aggregate sample retained W2 = 2100 gram. Weight sample passing 1.7mm IS sieve = W1 – W2 g = 2900 gram. Abrasion Value = (W1 – W2 ) / W1 X 100 = (2900/50000) X 100 = 58. Results. Los Angeles Abrasion Value of Aggregate = 58. IS Recommended Los Angeles Abrasion Value of Aggregate for Pavements
The frictional properties of the coarse aggregate used in asphalt concrete are a major contributor to the friction of the surface mixes. Selecting an aggregate that is not only polish and crush resistant to withstand the mechanical degradation and grinding under traffic loading, but also has a low friction loss rate and reasonable friction life is vital. A …
This test, prescribed by BS 812: Part 110:1990, assesses the resistance of an aggregate to crushing, indicating its ability to withstand compressive loads.
The crushing characteristics of coarse aggregates for asphalt concrete were investigated under static and dynamic aggregate crushing value tests (ACVTs). The effect of various compaction loads was also examined by using a Marshall hammer, gyratory compactor and steel roller. Six types of coarse aggregates were tested, …
