Aggregate Impact Value AIV ? ? × Calculate the mean of the two results to the nearest whole number Report the mean as the aggregate impact value unless the individual results differ by more than 015 times the mean value In this case repeat the test on two further specimens
Procedure of Aggregate Impact value test The test sample normally aggregates sized 100 mm to 125 mm the aggregates should be dried by heating at 100110 0C for a period of 4 hours and cooled Sieve the material through 125mm and 100 mm IS sieves The aggregates passing through 125 mm sieve comprises the test material
The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load Procedure of Aggregate Impact Test The test sample consists of aggregates sized 100 mm 125 mm Aggregates may be dried by heating at 100110° C for a period of 4 hours and cooled
DETERMINATION OF AGGREGATE CRUSHING VALUE DETERMINATION OF AGGREGATE IMPACT VALUE 1 AIM 3 To determine the impact value of the road aggregates 4 To assess suitability of aggregates for use in different types of road pavement 2 PRINCIPLE Resistance to abrasion of aggregates is determined in laboratory by Los Angeles test
A small portion of 14–10 mm sized coarse aggregate particles is confined in a steel pot and subjected to 15 blows by a small hammer in a standardised test rig after which the ‘ aggregate impact value’ AIV is determined from the fine material generated expressed as a percentage of the original weight of the test portion BS 812 Part 112 1990 130 Lower values indicate aggregates which are tougher or
Method for determination of aggregate impact value AIV AMD 8772 Superseded but remains current Buy from BSI BS 8121121990 Testing aggregates Method for determination of aggregate impact value AIV AMD 8772 Superseded but remains current Publication Year 1990 Document Status Caution Newer versions Abstract
51 Impact Value as determined using the standard 45 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
The physical and mechanical properties of the brick aggregates derived from the two methods were tested and compared In all types of brick aggregates size shape and strength properties such as flakiness and elongation indices aggregate impact and crushing values and Los Angeles abrasion value showed lower values for manually crushed
Aggregate Impact Value Civil Engineering The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS 2386 Part IV 1963IS Sieves of sizes 125mm 10mm and 236mm A cylindrical metal measure of 75mm dia and 50mm depth A tamping rod of 10mm circular cross section and 230mm length rounded at one end and price
