<strong>EXPERIMENT</strong> <strong>NO</strong><br />
<strong>AIM</strong> :-<br />
<strong>To</strong> determine the softening point for the given sample of bitumen<br />
APPARATUS :-<br />
Softening point <strong>test</strong> set up .<br />
FIGURE :-<br />
THEORY :-<br />
PROCEDURE :-<br />
The softening point of any substance is the temperature at<br />
which the substance attain a particular degree of softening under specified<br />
condition of <strong>test</strong> . The softening point of bitumen is generally found o ut<br />
by using ring and ball apparatus.<br />
A brass ring containing <strong>test</strong> sample of bitumen is suspended<br />
in liquid like <strong>water</strong> . Some times glycerin can be taken at a given bitumen<br />
sample and set up is placed in liquid . The liquid is heated after due coarse<br />
of time the steel ball fall down because the bitumen is very soft . Th e<br />
temperature at which the ball falls is called as softenin g point . Hard<br />
bitumen softens at high temperature.
