OBSERVATION TABLE :-<br />
Penetrometer is penetration <strong>test</strong> apparatus<br />
The penetration <strong>test</strong> determines the hardness and so ftness<br />
of bitumen by measuring the depth of needle in mm to which a standard<br />
loaded needle penetrates vertically 5 sec . The sample is maintained at 250<br />
C.<br />
A bitumen sample of depth about 15mm. is taken into a<br />
container . The sample is arranged on the instrument that the standard<br />
needle just touches the surface of the bitumen sample . The dial is set to<br />
zero . Now initial reading is taken and the needle is released for 5 sec. and<br />
the final reading is taken on the dial gauge . Three reading should be tak en.<br />
Each <strong>test</strong> should be <strong>perform</strong>ed for at least 10 min apart from each other and<br />
the mean value is taken .<br />
