The test also will determine the quality of the aggregate. The L.A. Abrasion test is widely used as an indicator of the relative quality or competence of mineral aggregates. Standard Test Methods are: AASHTO T 96 and ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine
ATM 313. The aggregate shall have a percent of wear not more than 50 at 500 revolutions as determined by AASHTO T 96 and shall not show evidence of disintegration nor show loss greater than 12% when subjected to 5 cycles of sodium sulfate accelerated soundness test using AASHTO T 104. 208-2.2 CRUSHED AGGREGATE SURFACE COURSE.

loads. The test used for evaluating this property is the Los Angeles Abrasion test (AASHTO T 96). Briefly, this test requires the aggregate to be placed in a metal drum along with a charge of steel balls, and the drum rotated 500 times. The steel balls are required to be approximately 1 27/32 in. in diameter and have a weight of 390 to 445g.
Feb 09, 2016 (Example: Clay lumps, shale, organic material, etc.). To find presence of deleterious materials in aggregate refer IS: 2386 – part-2. The sand-equivalent test, described in AASHTO T 176, is a method of determining the relative proportion of detrimental fine dust or clay-like materials in the portion of aggregate passing the No. 4 (4.75 mm) sieve.
Sep 12, 2015 Crushing Test Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS: 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied ...
5.1 Impact Value, as determined using the standard 4.5 kg (10 lbm) hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates, stabilized soil and recreational turf. Impact Value is one of the properties used to evaluate ...

Aggregate Crushing Value and 10% Fines Value: BS 812 - 110: 9. Uniaxial Compressive Strength Test: ASTM E 4: 10. Sodium Sulphate Soundness Test(5 ...
Toughness 50 * Aggregate Crushing Value (MS 30: Part 8: 1995) Relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Test specimen compacted into steel cylinder subjected to load applied tru plunger. Degree of crushing assessed by sieving test and taken as a measure of aggregate crushing value (ACV)
Aug 11, 2020 This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.
Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 C to 110 C then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.
Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.
