Various Lab Test On Aggregates Aggregate Impact Value 4. Aggregate Abrasion Value 5. Aggregate Crushing Value Just click on the names of the tests above to know the entire procedure of how we perform these tests. WMM, Soil sample. Give the deatial about the sampling of CBR testing. Thanks, Laboratory Manual of Test Procedures, February 2018. This edition completely rthe eplacesFebruary 2017 Laboratory Manual of Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine Organic Impurities in Fine Aggregate for Concrete Determining the Percent of Fractured Particles Determination of Aggregate Impact Value Impact Test on Aggregates is done to carry out to: Determine the impact value of the road aggregates, Assess their suitability in road construction on the basis of impact value.

7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN ROAD WORK. Suryakanta September 12, 2015 The test sample is weighed and placed in the test cylinder in three layers each layer being tamped again. The specimen is subjected to a compressive load of 40 tonnes gradually applied at the rate of 4 tonnes per minute. The aggregate impact test has been standardized by the British Standard Institution and the Indian Standard Institution.

The aggregate impact value indicates a relative measure of the resistance of aggregate to a sudden shock or an impact, which in some aggregates differs from its resistance to a slow compressive load. Condition of sample Procedure to determine Aggregate Impact Value i) 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.

FIELD SAMPLING AND TESTING MANUAL. TESTING PROCEDURES FOR ALL TESTS. For coarse aggregate or composite of coarse and fine aggregate, sample from trucks. Take samples from a minimum of three trenches. Dig trenches across aggregate are desired, this test method is used on the aggregate sample prior to 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
