Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.

Read definition, apparatus, IS code, procedure, observations, formula, result and lab report about aggregate impact value test. Apparatus Required for Aggregate Impact Value Test:-Impact testing machine; Cylinder; A straight metal tamping rod of circular cross-section 16 mm in diameter, 45 cm to 60 cm in length and rounded at one end.
The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Therefore, an L.A. abrasion loss value of 40 indicates that 40% of the original sample passed through the No. 12 (1.70 mm) sieve.
Aggregate impact value (The value of aggregate impact test) = (W1/W2)*100. The value of aggregate impact test should not be more than 45% by weight of aggregates, used for concrete other than wearing surface. An impact value 35% is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40%.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
Aggregates Impact Test (AIV) Introduction: Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition. 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 ...
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
TEST. In conclusion,the percentage of aggregate's wear depends on the quality of aggregate. In this test, we can conclude that: The loss of aggregate = 1663 g. The percentage of wear = 33.26%. Lower abrasion loss values indicate the aggregate was tougher and more resistant to …
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
The strength of coarse aggregates is assessed by aggregates crushing test. The crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred. 2.0 Objective.

Sieve the whole specimen in the tray on the 2.36mm sieve until no further significant amount passes. Weigh and record the masses of the fraction passing and retained on the sieve to the nearest 0.1gram (M2+M3 respectively). If the total mass differs from the initial mass M1 by more than 1gram, discard the result and test a further specimen. RESULTS Pan weighs=2448.5g Pan +aggregate=3053g ...
