DISCUSSION:* Interpret and comment the results obtained

             1. Report thesource and type ofbitumen.
             2. Report the bath liquid used in the test and quotes the mean softening point of your
                specimen. Comment on the value obtained.
             3. Ifthe two test temperatures differ by more than 1°C, offer an explanation.

             4. Using the Nomograph given, determine the penetration index for the  samples tested
                based upon the softening point test temperature value  known.
