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.

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 .
The Los Angeles (L.A.) 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 high quality HMA. Apparatus: Steel Spherical Balls
Feb 03, 2012· The strength of coarse aggregates is assessed by aggregates crushing test. The crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm
Conclusion For Aggregate Impact Value Test However, the engineering values of aggregates extracted from reclaimed asphalt pavement have not been fully Figure 3: (a) Aggregate Crushing Value and (b) Aggregate Impact Value Apparatus Impact value of an aggregate test gives an idea of toughness of the aggregate to resist fracture under the CONCLUSION.
The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.
The LA abrasion test is the most widely used method for testing aggregate abrasion (Wu et al., 1998).In Australia, the LA abrasion method is available in the Australian Standards (AS 1141.23), whereas other standards, such as ASTM C131/C131M, may be used in other parts of the world.
