In conclusion, our group now can determine the aggregate impact value (AIV) of aggregate. Our test gives the average impact value of 37% and it is exceeding the maximum permissible aggragate impact value according to …
Resistance to abrasion of aggregate is determined in laboratory by Los Angeles test machine. The principle of Los Angeles abrasion test is to produce abrasive action by use of standard steel balls which when mixed with aggregates and rotated in a drum for specific number of revolutions also causes impact on aggregates.
From the experiment, we can say that it is very important to test the aggregates in order to construct a quality pavement for the highway construction. Thus, the results of the experiment, the aggregates impact value is 19% from …
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.
Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in Los Angeles Machine.
The document describes an experiment to determine the aggregate impact value of a given specimen through a standardized test procedure. Three samples were tested by subjecting aggregates retained between 10mm and 12.5mm sieves to 15 blows from a falling hammer. The percentage of material passing a 2.36mm sieve was …
Aggregate samples obtained from the deposits were analyzed in the laboratory to determine their mechanical properties (aggregate crushing value and aggregate impact value).

Aggregate impact value test is to determine the response of aggregates to different kinds of loads that the aggregates will be subjected. It is the ability of aggregates that can resist the sudden impact of load.
Correlation analyses among the measured parameters identified the aggregate crushing value as a promising alternative test method to quantify the crushing potential of aggregates and to adjust the gradation accordingly to produce mixtures with optimized volumetric properties.
Report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the aggregate impact value.
Impact value of the aggregates is useful to understand the strength of the concrete against impact. If aggregates are used in road construction, then are subject to get impact due to heavy road traffic. This causes crushing the aggregates and hence aggregates impact value is important to find out. The aggregate impact value is a …
DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812-112) Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of …
This lab report summarizes an experiment to determine the aggregate impact value (AIV) of a sample. The AIV test subjects aggregate samples to standard impacts from a dropping weight to assess their resistance to shock or impact. The procedure involves compacting 350g of aggregate between 10-14mm in size into a cup, subjecting it to 15 blows ...

The aggregate Crushing Value Test is an important test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm in diameter and 25 mm in height.
The road is subjected to motion pressure continuously. Aggregate crushing value test ensures that the aggregates used for road construction can able to ...
The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load.
The aggregates should therefore have sufficient toughness to resist their disintegration due to impact. This Characteristic is measured by impact value test. 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.

Theory: The " aggregate crushing value " give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. It's the percentage by weight of the crushed (finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the ...
