Asphalt Cements and Mixtures There are two methods to measure the aggregates’ ability to degradation and are as follows: The Los Angeles (L.A) abrasion test method to indicate aggregate roughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA. Procedure ­  A sample of aggregate retained on the No. 12 (1.70 mm) sieve is placed inside a rotating steel drum containing a specified number of steel spheres or “charge”. As the drum rotates, a shelf inside the drum picks up the aggregate and steel spheres. The shelf carries them around until they drop on the opposite side of the drum, subjecting the aggregate to impact and crushing. Then, the aggregate is subjected to abrasion and grinding as the drum continues to rotate until the shelf picks up the contents, and the process is repeated. The drum is rotated for a specified number of revolutions. Afterward, the aggregate is removed from the drum and sieved on a No. 12 (1.70 mm) sieve. The aggregate retained on the sieve is weighed and the difference between this weight and the original weight is expressed as a percentage and reported as the L.A. abrasion loss value. Aggregate Impact test is to determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) – 1963. This test is to measure the resistance of an aggregate to mechanical degradation. Procedure ­ The test sample should conform to the following grading. Passing through 12.5mm IS Sieve – 100% and Retention on 10mm IS Sieve – 100%. Sample should be oven­dried for 4hrs at a temperature of 100 to 110 C and cooled. 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. Then hammer should be raised to 380mm above the upper surface of the aggregates in the cup and allowed to fall freely onto the aggregates. The test sample should be subjected to a total of 15 such blows, each being delivered at an interval of not less than one second. The sample should be removed and sieved through a 2.36mm IS Sieve. The fraction passing through should be weighed. The fraction retained on the sieve should also be weighed and if the total weight is less than the initial weight by more than one gram, the result should be discarded and a fresh test done. The ratio of the weight of the fines formed to the total sample weight should be expressed as a percentage and two such tests should be carried out and the mean of the results should be reported. No. of gyrations: N initialhe number of gyrations used as a measure of mixture compatibility during construction. A mixture designed for greater than or equal to 3 million ESALs with 4 percent air voids at N designhould have at least 11 percent air voids at Ninitial N designThis is the design number of gyrations required to produce a sample with the same density as that expected in the field after the indicated amount of traffic. A mix with 4 percent air voids at N  is desired in design mix design. N max: The number of gyrations required to produce a laboratory density that should never be exceeded in the field.
