1  Scope
The objective of the Test Method is to set out two procedures which use a ring and ball apparatus for the determination of the softening point of bitumens and related roadmaking products. The materials concerned have a softening point in the range 30 °C to 157 °C.
2  Application
ASTM D36/D36M-14e1 is the 2014 edition. Only the 2014 edition shall be used in accordance with this Test Method.

Delete clause and replace with the following: This Test Method determines the softening point of bitumen and polymer modified binders (PMBs) in the range from 30 °C to 157 °C using a ring-and-ball apparatus immersed in distilled water (30 °C to 80 °C] or glycerol (above 80 °C to 157 °C]. Delete clause and replace with the following: Values are stated in either SI units or imperial units in this Test Method. All measurements shall be made using SI units.

Grade of glycerol which has a purity≥than 99 %. . First sentence, delete “glycerin” and replace with “glycerol”. Delete section, including Clause 8.1. Calculate the softening point of the material by averaging the softening point results obtained for the two rings. Delete clause and replace with the following: Depending on the bath medium used, choose Clause 11.2.1 or Clause 11.2.2. Delete clause and replace with the following: For softening point results obtained in the water bath: if the mean result obtained is between 28 °C and 80 °C report the result. For mean softening point results above 80。C, reject the result as invalid and repeat the determination in a glycerol bath. Delete clause and replace with the following: . For softening point results obtained in the glycerol bath: if the mean result is 84 °C or below repeat the determination in a water bath. If the mean water bath result is 80 °C or below report that result otherwise report the mean result obtained in the glycerol bath.
