dicting aggregate impact value and aggregate crushing value. Wylde (11) reviewed and investigated the road failures, aggregates, and test methods used in Australia. He concluded that the absolute significance of test results was not apparent. He also found that the consensus was that the results of a range of test methods should be interpreted in the light of experience with the aggregate in ...
· Aggregate Crushing Value. Introduction. The principal mechanical properties required in stones are satisfactory resistance to crushing under the roller during construction and adequate resistance to surface abrasion under traffic. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads.
DISCUSSION. Los Angeles (LA) abrasion test is a method to measure the abrasion resistance in which the sample and a set of steel spheres are tumbled inside a closed, hollow, steel cylinder, about 700 mm diameter and 500 mm long, which is rotated on a horizontal axis. abrasion test studies all possible reasons causing wear. In the abrasion machine Attrition, Abrasion and Crushing are ...
· Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.
gate of 'aggregate crushing value' 30 or higher, the result may be anomalous, and in such cases the 'ten percent fines value' should be determined instead. NOTE 2 The standard aggregate crushing test shall be made on aggre a IS Sieve and retained on a IOmm IS Sieve. If required, or if tR ate passing e standard size is not available, other sizes up to 25 mm may be tested but ...
· For the compressive strength test of concrete cube two types of specimens either cube of 15 cm ×15 cm × 15 cm or 10cm × 10 cm × 10 cm, depending upon the size of aggregate, are used. For most of the construction works cubical moulds of size 15 cm × 15 cm × 15 cm are commonly used.
Aggregate Crushing Value Test The objective of this test is to: Determine the aggregate crushing value of coarse aggregate; Assess suitability of coarse aggregates for use in different types of road; Apparatus. A steel cylinder 15 cm diameter with plunger and base plate. A straight metal tamping rod 16mm diameter and 45 to 60cm long rounded at one end. A balance of capacity 3 kg readable and ...

but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes, Gourley and Ohikere [5] recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess aggregate durability. The MicroDeval abrasion test was developed in France during the 1960's. It is a wet ball mill test. A kg graded ...

APPARATUS: i) Cylindrical measure and plunger ii) Compression testing machine iii) IS Sieves of sizes , 10mm and PROCEDURE: i) The aggregates passing through and retained on 10mm IS Sieve are ovendried at a.
Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.
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%. If it is more than 30 % then 10% finer ...
The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of 13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS As in SABS Method 842. 3 METHOD Follow SABS Method 842. 4 CALCULATIONS Do the calculations as set out in SABS Method 842 and report the force to the nearest 10 kN for forces of .
