A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers hot-applied crack filler for usein fill
3、ing cracks in asphalt concrete and portland cementconcrete pavements.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Co
4、mbiningvalues from the two systems may result in nonconformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and de

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
21、eating temperature withinthe required 1 h time as stated in Practice D5167. The sampleshall then be maintained at the safe heating temperature whilebeing continuously stirred until a total of 90 min from the timethe first segment was added to the melter has elapsed.

PRECAUTIONS ON USE AND APPLICATION OF CRACK FILLER, HOT-APPLIED, FOR ASPHALTCONCRETE AND PORTLAND CEMENT CONCRETE PAVEMENTSX1.1 Some, if not all, of the kn
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
33、ation geometries are com-monly used for filling cracks with crack filler for various fillingsituations. Application should be performed in a neat, work-manlike manner.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin th
