General Requirements3.1 The hot-applied crack filler shall be a compound thatwill effectively fill cra

7、cks in both asphalt concrete and portlandcement concrete pavements. The crack filler shall resist soft-ening and pickup by vehicle tires at ambient summer tempera-tures when used in an appropriate manner. The material shallbe capable of being heated to the specified safe heatingtemperature (see 4.1)

8、 in appropriate melting units, shall becapable of being effectively applied to pavement cracksthrough pressure fed melter-applicator equipment, and shall besuitable for filling cracks that are a minimum of 9.5 mm 38 in.in width (see Appendix X1).4. Physical Requirements4.1 Safe Heating TemperatureTh

9、e safe heating tempera-ture is the highest temperature to which the crack filler can beheated and still conform to all requirements of this specifica-tion. The safe heating temperature shall be a minimum of 11C20F higher than the manufacturers minimum recommendedapplication temperature. For testing

10、purposes, the pouringtemperature for specimen preparation shall be the safe heatingtemperature recommended by the manufacturer. The safeheating temperature shall be shown on all containers and shallbe provided to the testing agency before any laboratory testsare begun.4.2 Softening Point The softeni

Sampling5.1 Samples may be taken at the plant or warehouse prior todelivery or at the time of delivery, at the option of thepurchaser. If

16、 sampling is done prior to shipment, the inspectorrepresenting the purchaser shall have free access to the materialto be sampled. The inspector shall be afforded all reasonablefacilities for inspection and sampling which shall be conductedso as not to interfere unnecessarily with the operation of th

17、eworks.5.2 Samples shall consist of one of the manufacturersoriginal sealed containers selected at random from the lot orbatch of finished material. A batch or lot shall be considered asall finished material that was manufactured simultaneously orcontinuously as a unit between the time of compoundin

18、g andthe time of packaging or placing in shipping containers.5.3 The crack filler portion for testing shall be obtainedfrom the selected manufacturers original container in accor-dance with Practice D5167. The sample portion for testingwhich is added to and heated in the melter shall weigh 800 650 g

19、 28 6 2 oz.6. 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 than 288C 550F. Add the seal

20、antsample 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 heating temperature withinthe

21、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. Speci-mens for physical testing are then poured from the heate

PRECAUTIONS ON USE AND APPLICATION OF CRACK FILLER, HOT-APPLIED, FOR ASPHALTCONCRETE AND PORTLAND CEMENT CONCRETE PAVEMENTSX1.1 Some, if not all, of the known materials conforming toth

29、is 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, constructed as a double boiler, with th

30、e 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 filler should be heated to a temp

31、erature 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, orother contaminants so tha

32、t adhesion to the crack surfaces isD5078/D5078M 112developed. Cleaning methods used shall be as required forspecific job conditions. Methods commonly used includeblowing with compressed air, routing, or use of a wire brushtype cleaner.X1.3 Several different application geometries are com-monly used

33、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 this standard.
