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. To determine Aggregate Impact Value Using Impact Testing Machine. Apparatus: – Impact Testing Machine: – Weight of hammer is 13.5 to 14.0 kg and Height of Fall is 380±5 mm. Sieves: – required are 12.5, 10.0 and 2.36 mm. Weight Scale: – To measure Weight of the sample. Procedure: – REPARATION OF SAMPLE i) The test sample should .
The testing machine then places the measure, with the aggregate in it. An impact load is exerted by releasing a hammer from a known height to strike the aggregate. The impact value is calculated as the resulting percentage of fines generated. Procedure. Collect the aggregate pattern passing via a 12.5 mm sieve and retained on a 10 mm sieve.Gilson aggregate testing equipment measures and evaluates the physical characteristics of fine and coarse aggregates for asphalt and concrete mixes. Size, shape, density, and strength of mineral aggregate all impact the long-term performance of . 5.1 Impact Value, as determined using the standard 4.5 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 .

(rlv;Sld). 2. ISt 5640.1970 2.1 The impact testing machine of the general form shown in Fig. I and complying with .This video (Animation, Animated Video) explains how to determine aggregate impact value (Aggregate Impact Test). Aggregate test || Coarse aggregate Test (Civ.To study the toughness property of the aggregates for concrete construction. EQUIPMENT. Impact testing machine: DESCRIPTION OF MACHINE. The Pendulum impact Testing Machine consists of the robust frame, the specimen support and measuring dial. The pendulum shaft is fitted in anti friction bearings. The pendulum is clamped to the pendulum shaft. The primary purpose of this test is to ensure that only durable and robust aggregates are used in construction. The test involves the use of a testing machine to subject the aggregates to impact loads. The machine comprises a base, cylindrical measure, and a hammer that falls through a given height to cause an impact on the aggregates.

Impact Test Fig-3 Impact Test Setup. The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine. 9. PROCEDURE The cup of the impact testing machine should be fixed firmly in position on the base of the machine and the whole of the test sample placed in it and compacted by 25 strokes of the tamping rod. The hammer should be raised to 380mm above the upper surface of the aggregates in the cup and allowed to fall freely onto the aggregates. Apparatus for Los Angeles Abrasion Test. The equipment is standardised in accordance with IS: 2386 (Part IV) – 1963 and comprises the following components:. Los Angeles abrasion machine.
