Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration This test is carried out by AASHTO T 96 or ASTM C 131 Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine...
The principle of Los Angeles abrasion test is to find the percentage wear due to relative rubbing action between the aggregate and steel balls used as abrasive charge Los Angeles machine made up of circular drum of internal diameter 700 mm and length 520 ,...
The Los Angeles LA abrasion test 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 ,...

The abrasion value of coarse aggregate may be determined by either Deval Machine or by Los Angeles machine Using Deval Machine Abrasive Charge The abrasive charge consists of 6 cast iron or steel spheres approximately 48 mm in diameter, each weighing between 390 and 445 g...
The aim of this experiment was to determine the strength of the aggregate using two methods one that measures how easily the aggregate is crushed by direct compression the aggregate crushing value and another that measures how easily the aggregate is crushed by simulating abrasion the Los Angeles abrasion...
