Highway elongation test
Discard all aggregate retained on the 630 mm bs test sieve and all aggregate passing the 630 mm bs test sieve then weigh each of the individual size-fractions retained on the sieves, other than the 63 mm bs. An elongation test is a destructive test used to characterize and quantify the ductility of a wire by measuring the amount of stretch in a wire sample after a failure in tension the mgs group tester stretches the wire to failure then provides the means to measure the sample.

Flakiness sieve test set 47-d0415 general description used to determine if aggregate particles are to be considered flaky, ie their thickness is less than 06 of their nominal size. Ductility is a mechanical property of materials that refers to the degree of plastic deformation a material can sustain prior to fracture if little or no plastic deformation can occur, the material is brittle. Procedure: ductility is the property of bitumen that permits it to undergo great deformation or elongation ductility is deﬁned as the distance in cm, to which a standard sample or briquette of the material will be elongated without breaking.
