aggregate is obtaining a good sample of the material to be how to get a good representative sample from a crushing operation, a stockpile, a windrow, or a paving operation is absolutely critical to getting good test results from a lab. Poor sampling techniques have led to more controversy in aggregate testing than any other factor.

The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a mm BS test sieve. If required, or if the standard size is not available,

Note 6: AASHTO T 27 allows for coarse aggregate to be run in a moist condition unless the nominal maximum size of the aggregate is smaller than mm (1/2 in.), the coarse aggregate (CA) contains appreciable material finer than mm (No. 4), or the coarse aggregate is highly absorptive.

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm

Sep 06, 2018· Preparation of test Sample: The material for the standard test shall consist of aggregate passing a IS Sieve and retained on 10mm IS Sieve 2. The aggregate shall be tested i a surface dry condition if dried by heating, the period of drying shall not exceed four hours, the temperature shall be 100 to 110 0 C and the aggregate shall be cooled to room temperature before testing.

The selection of proper aggregate for a given application is essential to attain the desired quality. Various characteristics are required to be determined for the selection of appropriate aggregate from the wide range available. Aggregate crushing value test apparatus is used for measuring resistance of an aggregate to crushing.

1 Obtain a sample of aggregate (about 50 kg) from three places in the stockpile: from the top third, at the midpoint, and from the b ottom third of the volume of the pile. 2 Place the field sample on a hard, clean level surface. 3 Mix the material thoroughly by turning the entire sample three times.

Sep 18, 2017· Aggregate Crushing Value Test Appratus; PREPARATION OF SAMPLE. Test sample consist of aggregate passing a IS sieve and retained on a 10mm IS sieve. The aggregate to be tested is dried in oven for a period of not less than 4 hours. PROCEDURE.

Methylene Blue Test Set. Aggregate Angularity Elongation equipment determines the shape characteristics fine and coarse aggregates to evaluate their suitability for asphalt and concrete mixtures. Calipers quickly determine percentages of flat and elongated particles in coarse aggregate fractions of 3/8in () or larger.

The test sample is subjected to a total 15 such blows, each being delivered at an interval of not less than one second. The crushed aggregate is then removed from the cup and the whole of it sieved on the sieve until no further significant amount passes. The fraction passing the sieve is weighed accurate to

SP/SM4:060418 SPECIFICATION FOR BASECOURSE AGGREGATE Page 4 of 15 Clay Index The clay index of the fraction of basecourse passing the 75 μm sieve shall not be greater than 3 when the aggregate is tested according to NZS 4407 : 1991, Test Clay Index Test. Plasticity Index

Crushing value test: The crushing value test was carried out by compression testing machine (CTM). The total load of 40 tones was applied at the rate of 4 ton per minute. The percentage crushing value was determined by divided the passing weight from total weight of aggregate.

(for soaked test refer to BS page 5, Cl and ) Test Procedure. The test will be performed in duplicate on the material passing the 14mm sieve and retained on the sieve. The aggregate used in this test will have been obtained from a bulk sample that was initially taken and prepared in the manner described in BS812:1989 Part 102.
