Heating6.1 Heat the material in accordance with Practice D5167.6.1.1 The oil bath in the melter shall be heated to atemperature between the sealant safe heating temperature and41.7C 75F above the sealant safe heating temperature, andin no case shall be more

20、 than 288C 550F. Add the sealantsample to the melter according to instructions in PracticeD5167. After the sample has been added to the melter, the oilbath temperature shall be regulated within the above listedtemperature limits to raise the sealant temperature to themanufacturers recommended safe h

29、own materials conforming tothis specification may be damaged by heating at too high atemperature, or by heating for too long a time. Care should beexercised to secure equipment for heating and application thatis suitable for the purpose. The material should be heated in akettle or melter, constructe

30、d as a double boiler, with the spacebetween the inner and outer shells filled with oil or other heattransfer medium. Positive temperature control, mechanicalagitation, and recirculation pumps should be provided. Othermethods of indirect heating satisfactory to the engineer may beused. The crack fill

31、er should be heated to a temperature that isat least the manufacturers minimum recommended applicationtemperature. Temperature should not exceed the material safeheating temperature.X1.2 Pavement cracks to be filled with material covered bythis specification should be dry and clean of all dirt, dust

32、, orother contaminants so that adhesion to the crack surfaces isdeveloped. Cleaning methods used shall be as required forspecific job conditions. Methods commonly used includeD5078/D5078M 11 (2016)2blowing with compressed air, routing, or use of a wire brushtype cleaner.X1.3 Several different applic
