ASTM D - 244 Modified Evaporation Test for percent of residue is made by heating 50 gram sample to 149 ° C ( 300 ° F ) until foaming ceases , then cool immediately and calculate results . 2 . Test procedure identical with ASTM D - 244 - 60 except that . 02 Normal Calcium Chloride solution shall be used in place of distilled water . 3 . Test procedure identical with ASTM D - 244 except that distilled water shall be used in place of two percent sodium oleate solution . 4 . Chemical Composition by ASTM Method D - 2006 - 70 . PC + A1 S + A2 PC = Polar Compounds + A1 = First Acidaffins S = Saturated Hydrocarbons + A2 = Second Acidaffins The rejuvenating agent shall have a record of satisfactory service as an asphalt rejuvenating agent and in - depth sealer . Satisfactory service shall be based on the capability of the material to decrease the viscosity of the asphalt binder and provide an in - depth seal .
