Oct 03, 2019 The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be
May 17, 2019 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load

Jan 06, 2019 The aggregates are used for the surface course of the highway pavements and they are subjected to wearing due to movement of traffic. L os Angeles abrasion test ASTM c131. When vehicles travel on the road, the soil particles present between the pneumatic tyres of vehicle and road surface creates the abrasion effect on aggregates.
Table1. Grading chart of Test Samples Tolerance permitted is 12 percent. According to the grading desire of our construction, grading is selected from the table. The sample from grading A, B, C, or D 5 kg of sample is taken and for grading E, F, G 10 kg of sample is taken. Abrasion charge according to our grading is selected from the given table 2 below is taken.
