Crushed Coarse Aggregate for Concrete TR 112 TR 113 Method B Lightweight Aggregate for Concrete TR 113 Method A Sand Clay Gravel ... Aggregate Test Report –DOTD Form No. 030745 (Figure A 1). III. Proper equipment and precautions are to be be handled.
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
Procedure of Aggregate Crushing Value. Take a sample of aggregates by sieving through and retained on 10mm. The aggregate shall be tested in dry surface conditions. If dried by heating, the period of drying shall not exceed 4 hours and temp shall be 100110 deg C.
BRITISH STANDARD BS 812110: 1990 Testing aggregates — Part 110: Methods for determination of Licensed copy: MLA Cornwall Public , Cornwall Enquiry and Information Service, Version correct as of 20/09/2011 15:09, (c) BSI aggregate crushing value (ACV)
Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads
quarries while the stone crushes, stone crusher dust that is abundantly available from crusher units at a lowpriced in many areas, maintain practical option for concrete river sand. Physical Properties of Fine Aggregate PROPERTIES TEST VALUES RS MS QS 1 Specific gravity Fineness modulus
Part 2: Aggregate for sprayed bituminous surfacing Part 5: Asphalt aggregates Part 7: Railway ballast This Standard is called up by AS 3600, Concrete structures. In this Standard, extensive reference is made to AS 1141, Methods for sampling and testing aggregates, which is designed to include all aggregate tests, not only those for concrete.
indied in this specifiion. Individual test results shall be forwarded to the Contractor, as they become available. Test data for each aggregate type shall be managed independently. When more than one source is used for supplying material, test data from each source and product shall be managed independently. Sampling

Aggregate Crushing Value (ACV) test indies the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken.
106 tests were performed and the plasticity index was zero (nonplastic) for all tests. Evaluation of Recycled Concrete DenseGraded Aggregate Base An enormous quantity of testing indies that re cycled crushed concrete consistently complies with all the parameters required for .
Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 partIV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
Recycled Aggregates from Inert Waste ... Where these tests are not satisfied, for example the aggregate does not conform to the relevant ... Waste gravel and crushed rock other than those mentioned in 01 04 07 01 04 08 May include excavations from mineral workings.
The aggregate shall be wellgraded and shall not vary from maximum to minimum of the specifiion ranges for consecutive tests. For Class "A" gravel base course, the field tests taken during any crushing shift shall yield an average of 65% or lower passing the sieve.
