toughness test of aggregate
The impact test on aggregates, also known as the Aggregate Impact Value (AIV) test, is conducted to determine the aggregate’s resistance to sudden impacts or shocks. This test is essential for assessing the toughness or hardness of aggregates, particularly those used in road construction. Detailed Impact Test on Road Aggregates with calculation of Impact value has been shown, also range of aggregate impact value is explained.Toughness is the p. 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 .
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 an aggregate to sudden shock or impact. Principle A test specimen is .California Test 211 May 2010. METHOD OF TEST FOR ABRASION OF COARSE AGGREGATE BY USE OF THE LOS ANGELES ABRASION TESTING MACHINE. STATE OF CALIFORNIA — BUSINESS, TRANSPORTATION AND HOUSING AGENCY. DEPARTMENT OF TRANSPORTATION.

Aggregate Impact Value Test Apparatus, Procedure and Uses. Due to movement of vehicle on the road the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregates should therefore have sufficient toughness to resist their disintegration on due to impact. This characteristics is measured by impact value .
It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft .Aggregate impact value is the measure of the resistance of an aggregate to sudden shock or impact. This test is conducted to determine the toughness of aggregates. This test helps to evaluate the quality of aggregates which can be used in road construction. The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties. The Izod impact test is similar to the Charpy test in that a weighted pendulum hammer strikes a test specimen containing a V-shaped notch. An Izod impact testing apparatus — which is essentially identical to a Charpy impact testing machine — is used to determine Izod impact strength.
The Aggregate Impact Value (AIV) test, outlined in IS 2386 Part IV, evaluates the impact resistance of aggregates. This is performed with an impact testing apparatus, using a specific procedure and sample preparation method. Aggregates acceptable for wearing surfaces in concrete should not exceed a 45% impact value and for bituminous concrete, 30%.
