Why the specimen used in a ductility test of bituminous material is briquette shaped??
Expert Solution
Step 1
One of the main reasons for maintaining a briquette shape of bitumen in the ductility test is that it locks the specimen while it is pulled in the test setup. Briquette shape does not allow the specimens to escape the jaws of the ductility test apparatus completely in a quick fashion. Unusual shapes like rectangle or square shapes with groves do not allow the bitumen to easily pass through the jaws.
